i agree 100% i'll definitely implement this... even though I don't have much time as jee is just around the corner but I'll do this as it will definitely help my understanding of the subject
i asked too much why to Einstein Photoelectric Concept, now i have my own theory and i don't completely believe in him, ab concept sir padha rhe hote hai toh pata chalta hai jo theory banai hai usme ye sab rely krte hai + new factors bhi find out krdiye jo science community me shayad help bhi krde 😆once i get this jee exam done, i will work on it making things more clear and experiment on it and provide mathematically proved theory to the science community, for now i wrote all the things that came to my mind for my future self to work on, i remember i also found missing parts which never explained in magnetic moment formula of Torque and Toppling from 11th
nah they serve less salary, i will first look forward to do things in my own way, my first goal is generate massive passive income so then i don't need to work for someone, i have collected a lot of resources, what to learn, what to serve, then i'll be free from the system, then work on my own research space, i'm being a curious kid from the start, i'm so excited to implement things@@CODE7X
Same bro mere pass bhi 300+ why how questions pade Hein class 9 se answer nahi mil Raha in questions ka teacher log ignore kar dete hain bolke syallabus mein nahi hai but mein laga rehta hoon
After reading about the theory of relativity . I am now more confused about time dilation synchronisation of clocks , lenth contractions. And many questions arises
Class 12th me pata laga ke hmm actually me tournament khel rahe hai pardh nahi rahe hai, I used to love Physics and Maths and even cleared olymiads like RMO and stuff, but JEE destroyed my passion for science completely now I am just revising theory mindlessly and solving questions for god knows why. Now I get it it's an engineering exam they want us to have good application not research Mindset to find new problems sad but true, BC KVPY bhi band kar diya inhone ab too
One of the biggest mistakes is not knowing ur mistakes or either ignoring them trust me I used bre in top 20 of my coaching but in 12th I started learning from mistakes rather than ignoring them now im in top 5
I relate to this video a lot. I am a dropper, and I have always tried to answer the whys throughout my jee preparation. I believe each concept can ve learned and reasoned out intuitively. But the biggest challenge I have faced is that my teachers never took the time to answer my whys. They'd point out the shortcuts. I'd keep asking why, but then they'd say “You give me the question you couldn't solve. Leave this aside” They've always focused on rote learning formulas(teachers). And I feel this is the major reason. Students are encouraged to memorise formula by coaching teachers, but no one is usually encouraged to think deeply, to ask “why” and to think for your ownself. I feel if I had a way to answer all my whys, because teachers dont usually answer me, hence I feel if I had any other source, I'd be much better off. I wish I knew how to clear all my whys. Another problem that I hace noticed, apart from the teachers not encouraging this “why” thinking, is that students are often scared to ask doubts. I've observed almost 80-90% of students are afraid to ask doubts as they feel their doubt will come off as stupid. I believe its important to be the stupid person in the room, as only then can you answer all your questions. Like it's necessary to be stupid and to admit you don't know stuff, than pretending and saying “yes” to teachers. Atleast when you're stupid you're learning a lot of new things. So to summarise: 1. Science is taught by teachers with the mindset “We need to learn science to crack jee” But it should rather be taught for curiosity, for knowledge. If it is taught like that, immediately it becomes clear to answer the whys. 2. Lack of resources to answer those why's. Not everyone has great teachers or teachers who care enough to answer your why's. I wonder if there are online ways to clear why's. 3. Most students are scared to ask doubts because they feel they'll come off as stupid.
Same here,. In fact there was a maths teacher in our coaching who used to mock students and make fun of them for asking questions which were silly for him. If this video was released 2 years back I could've .......
Droppers have to complete 2 years worth of course im a short duration of 7-8 months, that too at jee level. so it is practically not possible for a jee teacher to answer every why of every student. you can note down your whys and think about it at home are ask techers during doubt session or take extra time for them.
Tbh most of aspirant don't have cbse boards.. While most have state boards and they have different tbl different syllabus and even boards syllabus is very vast and has hard checking.. So we have to spend most time in root learning the thoery.. And thus lack practice..
Tru tru. I dont feel moving to next topic until n unless i can on myself build all concepts logically without help of notes or anything just active recall. (Obviously i just accept few things and move on when i think on why too much ) Yes this was kind of imp message that i should keep doing this and try to think more especially on maths concepts
Too good Sirji I got to know my physics weak point that I never asked why just mugging up thing by which I get good score but not able to explain things I am in 11th you really saved my time and I thick this video is worth watching!
I believe that a good teacher always answers whys and hows before introducing some new information or builds up to that information from common knowledge hence answering many of the hows and whys
I am a Dropper Now. But When I was Just studying The lecture it feel like 'I am Gaining Knowledge but at the same time i am lost the pvs knowledge'.it hits me & i stop my coaching take my time to understand all things. & then start at my own pace. Still a Long way to go. kyuki that small time was to large
Yess sir bhaiya mujha starting ma questions aata tha lakin mai bas usko yad karka chor deta tha abd teachers bhi jyada dhyan nahi deta tha .lakin ab sa mai chijo ko ratna ka bajaya sikhna aur samajhna ki koshish karunga ❤. Thankyou bhaiya ❤
Yeah this is true , I'm in 12th now , & I started my jee prep from 12th , and after some time I started to feel like the curiosity which I was having till 10th has left now maybe it's because of ccg & also i was not having confidence to ask anything there don't know why this happened with me I was not like that before
So basically tangent is a secant in which distance between the two points the secant cuts tends to 0 . 1. it touches just one point but may or may not cut the curve multiple times. 2. you can check the above point by drawing out some tagents on a sine curve 3.a tangent may lie above or below or both at the POT . Regarding the thing you are talking about at 7:00 , It is due to the reason that f'(0+) is not equal to that at f'(0-). Hence the function is not differentiable at that point(Known as cusp) and tangents at 0+ and 0- are completely different from each other . This is the only knowledge I have regarding your question . Please correct me or if possible provide the reason you think is more valid here . Thanks
if distance btw two points **tend to 0** , how can the tangent cut at single point, this also implies tangent passes through two points (extremely close)of any curve
7:00 you said that RHL and LHL are not equal and thus the function is discontinuous and non differentiable. Do you know why the function is discontinuous? And why f'(0+) =/= f'(0-) ? to easily understand this, just draw the tangents of a discontinuous function (any function ). At the point of discontinuity, you will see that the derievative "jumps" from on point on the cartesian to another. And thats why f'(0+) =/= f'(0-) and derivative is not defined at that point.
kisi bhi function mai f'(x)=0 par maxima minima and even point of inflection aa sakta hai extrema isiliye aata hai kyoki us point ke aage aaur peeche banne wale tangents ke slope ke sign different hote hai for example the function might go from increasing to decreasing or from decreasing to increasing, decreasing wale part mai tangents obtuse angle banati hai hence f'(x)
Thanks sir I am currently studying in standard 9 and with this video I am quite enlightened and will now try to ask more why as you said since I have more time and personally I think it is fun to learn stuff instead of remember

But, this is the best method I resource constraint country can afford.

.. And maybe during higher studies we can solve our 'why' ques by ourselves..... I think if a student has given so many things which have to be learned in depth ....then how will he understand all those things which are meant to be learned in higher studies.... Education system has given an overview of every topic in every subject ..
one of the biggest reasion is during a students journey ups and down bohot hote hai..... such as classes miss topics nahi samjha iske vajah many students they just tend to deviate... im not saying ups and downs are wrong but u should take them in a positive way to work towards them neither just leave them
Yes bro Idk why people ignore even the most fundamental things especially in Physics and Chemistry too,I wonder how deep thinking(fundamental level of thinking) is vanishing.People are running behind solving questions
At 3:36, it is because as x tends to +inf or -inf when 1)a > 0: f(x) tends to +inf in both cases. Hence, parabola opens upward 2)a < 0: f(x) tends to -inf in both cases. Hence, parabola opens downward At 5:00, it is not necessary that if f'(x) is 0, we get an extrema, rather it is the other way round, i.e. if (a, f(a)) is an extrema of the function f(x) then f'(a) = 0 The first statement is not true because a point of inflection can exist like at x = 0 for f(x) = x^3 where f'(0) = 0, but x = 0 is neither a maxima nor a minima for f(x), it is a point of inflection. If f'(a) = 0, f''(a) > 0 then the given point is a point of local minima If f'(a) = 0, f''(a) < 0 then the given point is a point of local maxima If f'(a) = 0, f''(x) changes sign at x = a then the given point is a point of inflection At 7:00, it is becuase say the curve is f(x) and the given sharp point is say (a, f(a)) f'(a-) is not equal to f'(a+) meaning f'(x) at x = a doesnt exist. If the slope at a given point on a curve doesnt exist, then it's tangent simply cannot exist
@@sunzitra2547 I hope you could understand the first part For the second part, you can complete the square to get ax^2+bx+c = a(x^2+bx/2a + b^2/4a^2) + c - b^2/4a^2 a(x+b/2a)^2 + (4ac-b^2)/4a^2 = y Case 1: a > 0 y = a non negative number + (4ac-b^2)/4a^2 As we can see, minimum value is attained when x = -b/2a (as a(x+b/2a)^2 = 0), we cant get any lower value as a(x+b/2a)^2 is non negative Case 2: a < 0 y = a non positive number + (4ac-b^2)/4a^2 As we can see, maximum value is attained when x = -b/2a (as a(x+b/2a)^2 = 0), we cant get any higher value as a(x+b/2a)^2 is non positive Unfortunately, i cant explain the details like point of inflection using only 10th grade knowledge For the third part, just notice that the point is sharp. When you try to draw a tangent (a line), what value of slope will you take? At the sharp point the slope suddenly changes, hence we cannot define a value of slope to be taken and hence we cant define a tangent at that point
@@sunzitra2547 f'(x) tells us the slop of f(x), when f'(x) is 0, it means f(x) has 0 slope at that point, now this can mean many things, 1. (Either f(x) graph is increasing, and then slope becomes 0, so f(x) becomes constant(Neither increasing nor decreasing) for a single point and then it starts dipping downwards, hence it form a traingle like thing => It forms a Maxima there, if you understood this, you will understand Minima point of inflexion etc also.)

I'd say, that studying books (mind you, not coaching modules) really helps build this knowledge. Also, I used the word 'studying' not just reading, you have to take time to read between the lines, not just skim through theory and you will surely acquire deep understanding

At 5:00, it is not necessary that if f'(x) is 0, we get an extrema, rather it is the other way round, i.e. if (a, f(a)) is an extrema of the function f(x) then f'(a) = 0
The first statement is not true because a point of inflection can exist like at x = 0 for f(x) = x^3 where f'(0) = 0, but x = 0 is neither a maxima nor a minima for f(x), it is a point of inflection.
If f'(a) = 0, f''(a) > 0 then the given point is a point of local minima
If f'(a) = 0, f''(a) < 0 then the given point is a point of local maxima
If f'(a) = 0, f''(x) changes sign at x = a then the given point is a point of inflection
At 7:00, it is becuase say the curve is f(x) and the given sharp point is say (a, f(a))
f'(a-) is not equal to f'(a+) meaning f'(x) at x = a doesnt exist. If the slope at a given point on a curve doesnt exist, then it's tangent simply cannot exist
Is it possible if you can explain this on the basis of what a 10th grader knows?
@@sunzitra2547 I hope you could understand the first part
For the second part, you can complete the square to get
ax^2+bx+c = a(x^2+bx/2a + b^2/4a^2) + c - b^2/4a^2
a(x+b/2a)^2 + (4ac-b^2)/4a^2 = y
Case 1: a > 0
y = a non negative number + (4ac-b^2)/4a^2
As we can see, minimum value is attained when x = -b/2a (as a(x+b/2a)^2 = 0), we cant get any lower value as a(x+b/2a)^2 is non negative
Case 2: a < 0
y = a non positive number + (4ac-b^2)/4a^2
As we can see, maximum value is attained when x = -b/2a (as a(x+b/2a)^2 = 0), we cant get any higher value as a(x+b/2a)^2 is non positive
Unfortunately, i cant explain the details like point of inflection using only 10th grade knowledge
For the third part, just notice that the point is sharp. When you try to draw a tangent (a line), what value of slope will you take? At the sharp point the slope suddenly changes, hence we cannot define a value of slope to be taken and hence we cant define a tangent at that point
@@mukundr9798 thanks it helped although the third one still confuses me.
@@sunzitra2547 It is better explained through concepts of class 12, so i think it is better for you to leave it
@@sunzitra2547 f'(x) tells us the slop of f(x), when f'(x) is 0, it means f(x) has 0 slope at that point, now this can mean many things, 1. (Either f(x) graph is increasing, and then slope becomes 0, so f(x) becomes constant(Neither increasing nor decreasing) for a single point and then it starts dipping downwards, hence it form a traingle like thing => It forms a Maxima there, if you understood this, you will understand Minima point of inflexion etc also.)
I think the main reason is not giving tests and cramping as well
How to get answers for these questions we asked , if we try very hard to find the answer but we didn't get
As I also prepared for jee last year the 6 lakh aspirations who can't even prepare 10-25 chapter in two years because of when they prepare for jee they take whole sallybus,at that time they don't know that even 30 chapter can give 100+ marks ,and what are the 30 chapter they think 2 year me bass 30 chapter karu , me saare karunga or itne le aunga.
That's why pw online is best❤❤❤
Revision also a big reason
Underrated comment
Ye v bda fact lgta h
This.
But, Bhaiya time bohot Kam hai
Abhi ek jee nikal ke advanced me implement kar sakte hai kya?
Reply me
Bhaiya UNDERSTANDING or MEMORIZING me kya difference hai
Is par ek Video banao PLEASE
Point sab to theek tha aapka lekin ek baat batye aab November aa chuka hai jabke paas shirf 2 se 2.5 months hai pratical baat karte hai iss video ko banane ka kya matlab aur fayda hua
Main thing is to relate everything u learn specially in physics whats why only phy is my best
Tangent is limiting case of secant 😂😂😂
Why why left my life ? 🤔.... Thankyou for reminding..
kha se kaunse book se padhe ki ye sab pta chale im in class 12 hamko ek bhi baat nhi pta plzz bataiye
Hello bhaiya mein aapki saari videos dekhta hoon aur usse practical aur motivational chije apply karta hoon apne daily life mein bhaiya aapne bahot books ki review ki hai bhaiya kya aap konsi bhi ek book giveaway kar sakte ho kya please bhaia
Idc about the rest, I just wanna know if that the reason for parabola being upward if a>0 is after 10th or not
Thank you bhaiya
I was ignoring these things
I will implement these this from today onwards
Bhaiya underated channels pt 3 banno na plz
Feynman technique bhi whys pe hi boil down karti hai , I 👍
Bhaiya aapse request hai please aap jee ke maths ko yt pr padhayie plz
Please koi batayega ka torque me F(perpendicular)*r hi kiu hota hay, ye multiplication kiu
So does that mean ki basics can help you?
They don't study bass pura 10 min ka video bana diya
7:00 us point(0) ke 0+ and 0- ka tangent (LSD,RSD) same nhi hai.. esliye cusp pe tangent nhi hoti.. (except vertical tangent) ab es me es se jyada kya hi jaan nege?.. kya wo bekar ki baat nhi hogi?.. kyuki eske aage ka sawal mai abhi tk nhi dekha..
💯
Thanks bhaiya me apki videos se inspired hu me ek college student hu yt pr video bnata hu , or apki videos dekhta hu
Really inspiring me 😅
Aur aisi video se sikhaa dena yrr plzzz 🙏🏻🙏🏻🙏🏻 plzzz yrrr like karunga share karuga na
bhaiya but how to decide that what to memorize and where to ask why
Meanwhile online students - hum to bol hi ni skte 😅😢
these are mostly online studying students. they cannot clear their doubts properly by commenting their doubts. And when they ask their school teachers, the teachers themselves arent thorough with the concepts. I am one of them, who wants to ask WHY but there is nobody to ask
Is there a CZcams channel which can teach concepts in such a way I can get an answer to all the WHY's?
sadly no...otherwise everyone would achieve a high score in JEE. Ultimately it all comes down to self study
Almost every jee aspirant is behind rank than knowledge and teachers are aligned to that, in that process students like me are left behind... Thanks for replying @@IronMan-wn8wh
Not all why's, but I can say that Professor Leonard taught in a great way about calculus. His channel, for me, has been a gold mine. He won't teach you on the JEE level (can't say that for sure, but I haven't given JEE so I won't comment). Do check him out
bhaiya i don't know i learn for 10 hrs per day but forgot many things, please help me to make a balance
Do we have to find our why by ourself or we have to take our coaching teacher, s help?
I've filled the board of 12th qualification wrong in my form.
Will there be any conflict?
Will there be a correction window?
Bhayiya ye why ko ab kaise khatam karre..teacher se puche to its basic recording as such deleted hai..or one shot me btate nhi..ye choti choti chize are getting accumulated i think i have time i am in 11th per way nhi pta..and yeah muje bhi yeh feel hua tha while doing questions
Ps- i tried organic by clearing doubts and muje goc yadd hoti hai infact kabhi kabhi questions bhi hote maybe its easy par fake confidence hi sahi...
M baata ta hoon kiu as a failed dropper. Kiuki padhai nahi karte. 11th 12th m lockdown tha tho social media anime vaagera se distract hoogaya fir drop year tak padhne ki aadat chuut gaai
Bhaiya mai 10th tak ese hi tha why wala but tab time jyada aur syllabus kam tha but ab syllabus cover karne ke chakkar mai why puchna bhul gaya but thanks for reminding me

Can you provide a resource which has this amount of in depth knowledge?
Bhai ye bhaiya ne Jo sari chije batai hai wo actually basics hai.....har kitab me ya har CZcams ki vedio me milenge.....agr dhyan se padha to....yahi bataya unhone ki direct formula vagre rate to ye pta nhi hoga
I'd say, that studying books (mind you, not coaching modules) really helps build this knowledge. Also, I used the word 'studying' not just reading, you have to take time to read between the lines, not just skim through theory and you will surely acquire deep understanding

I completed my Schooling till 10 from Sainik school.Aftrr that I came to kota in hope ki I will work hard and get IIT .pahale toh sab samajh aata tha classes me lekin dheer dheere samajh nhi aane laga ,mai Ghar jakar CZcams par phir lecture dekhta,class ki recording sunta lekin is se topic toh CLR ho jata lekin home work nhi Banta yahi chalta raha dheere dheere mujhse ek bhi questions nhi ban ne Lage aur mujhe class ka bhi kuch samjh nhi aat phir bhi mai class jata lekin after 10months of journey aaj na mujhse homework banta na class me Jo padhata woh samjh aata ,Aabhi tak Jo padha kuch pata nahi
I am just of nowhere ,I do not know what to do ? Plz help
Try to use CZcams more effectively, visit channels like physics galaxy, Mohit tyagi, eduniti, etc.
So much contont is available on youtube and majority of it is not at the level of advanced preparation, Ashish Arora sir physics galaxy said this in one vide

There should be why 1 million JEE aspirant can't even scoee 90 marks in JEE mains because at 90 marks you will get 90 percentile about and it means you have score more than 90% of the students who appeared for exam and if we calculate 90% of 12 lakh it will be more than 1 million.
