Hamare teacher sirf course jaldi complete krne ke liye jldi jldi krte hai ouur smjh nhi ate hai 😑
But apki video dekhne k baad sb clear ho gya💜😊
Sir 12 ka phala chapter hi tough kyu rakha h starting mai hi confidence down ho gyega !!
Sahi bola yr
If you already have that mindset it will be hard change your mindset 💪🏽
Starting 3rd Chptr se krte
Kitne percent bane...?
Bhai kuchh ni hard hai mehnat karo sab aasan ho jayega👍🏻👍🏻
Sir 12 ka math first chapter na students ka mood off kar deya hai😂😂😂
Skip this chapter

Yes sir 😂😂😂
No doubt +crystal clear + easily understand concept = Nexa classes.😇😇
ಠ∀ಠಠ∀ಠಠ∀ಠ
😅
Sir why u didn't use ncert justification in any of the number here ❓
Because unhune sirf injective and surjective pusha hai justification nhi
b
Cause vaha pr question mae he ya vaha pr bola hy ki justification k zarrurat nhi h..😅
Yesss
I'm thinking the same
Maths leke galati kar dya maine 😂😂 maa kasam rouna aaraha hain 😅😂
Yes😢😢😢😢
Absolutely right
Lage rho mere Bhai, pass ho jayega
Right 😢😅
😂😂😂 lekin mai toh complete karke he rahunga
Sir I have cleared my all douts which I have in my mind earlier your teaching skills are too good very neatly you make understand us I thought earlier maths is a boring subject... But now you made it interested now at first I took maths nootbook and open your channel on CZcams and sir thanks alot for this type of knowledge you are the strength of us all 😊
Bhai student ho ya teacher
धन्यवाद मास्टर साहब🙏
Thanku sir your teaching way is superb
Thanks sir in the good solution 👍👍👍

Sir -1 ka cube -1 hi hoga to phir wo one one kaise hoga
Excellent explanation
Very helpful video thanku so much sir
Thank you so much sir 🥰
This way is not correct as per ncert
If you are proving it by taking example your marks will be deducted
Sir ek request h aap hindi medium ke students ko bhi padhaiye kyuki mere jyada tar friend relation ke bacche maths subject se paresaan h aur unke pass koi coching ki bhi subidha nhi h yadi aap hindi medium se padhate h to mai unhe sugestion de sakooga baaki aapne saare friend se aapka chanal like Suscribe kra dia h maine
Thank you sir 😊🙂🙃
Sir function jab sabhi domains ki image bane tab hi banta Hain par Aapne (i) wale mein sab domains ki image nhi banayi toh Woh function kaise huya?
Sir meko pehli baar me nhi aaya but second time me fir se introduction dekha to aaya thankyou sir ❤
Thank you sir

Sir Q.2 ke v part mei -1 ka cube -1 hoga aap ne 1 hi le liya hai
v ) number mai -1 ka ³ -1 ayaga and 1 ka ³ 1 ayaga 👏👏
Sir please use NCERT justification, we need that for our exam
Sir aab ncert justification ka kya
Ye sirf 1st question ke liye tha
Is question me karna chiye tha ncert justification isme doubt solve ho jate
Sir mere ko 1 part and 2 part me clarity nahi aa rahi hai according to ncert justification
😢😢😢😢
Thanks sir❤❤
Thank you so much sir...
I am doing by this method bcauz its easy but my school teacher is telling me that it is not perfect and i should do by his method(which is complex).
Suggest me what should i do 😢
Agar justify karne ke liya kaha ho tb ncert wala method use hoga
8:08 Can anyone help me out with this question, left oval is meant to be Domain but sir says there are +-1 +-2 in Co Domain where +-1 and +-2 doesn't belong, Co Domain consists of Range not negative integers as the condition f(x) = x² is meant to be in Co Domain's Oval.
Pls help me to get clarity on this.
because they come in z that's why 👍🏼
Same as 11:14
For more clarity see 16:15
You are great sir 👍👍☺️
Sir (v) wala injective kse hoga +-1 same image form krre h
It's wrong 😂
Very very much sir😊😊😊
Sir mai apke channel se padh kr 100 out of 89 ke kr aya math me 🙏🙏❤️❤️❤️❤️
Sir maine aapka channel apni sari frnds ko suggest kiya tha bhut phele aur ab wo sabhi yhi se kam krti hai 🙂🙂🙂🙂
I have some doubt of this question.....
To Khushi ke comment me kyu comment kr raha hai tharki khi ka😂
You are great Sir
Sir if we use this method .. board will give us mark..?
💯
sir 3rd part me agr hum root ka square krege to 2 ayega to not surjective kaise hua sir
-1 cube is also =-1
Than you write 1
That's worng
Alag alag likh lo 2 ka jaisa tab b unique image banegi bro 1 ki 1.... -1 ki -1😂 thoda. To dimag use krlo 😅
Sir iska justification kese kare plzz tell me
Sir apna integer main f(x) = x^2 mai apne not injective likha but apna x^3 ki term mai injective likha ha sir -2 ,2 ka range to 8 hai dono ka fir one to one kesa hua
-2³ is -8 while 2³ is 8
X^3 casee -2and 2 ka 8 and -8 range aa rha dono different hai so injective aur ,case x^2 me domain 2 and -2 ka same range 4 aa rha so not one one (not injective function), understand!!
Sir jaise aap answers solve karte hai kya us tarike se exam me likh sakte hai
Yes
@@nexaclasses thank you for reply sir
ok sir i sub. chenal
Full support sir.
Aapka padhya hua samjh me aata hai clear koi daut nahi fasti questions ka. Thanks sir
15:37
Sir -1 ka cube -1 hi hoga to phir wo one one kaise hoga
One one hoga par onto nhi hoga
Sir doubt on onto condition range is subset of codomain, it not satisfying the condition range should equal to codomain?? Kindly give me reply for this query
To ishme doubt kya hai.....jab condition setisfy nahi ho Rahi hai to wo upto nahi hai....... simple 😊
Bhiya ji aap introduction karlo .....
Ya fir ek bar fir se lec kar lijiye sar doubt solve ho jayege❤....kyu ? Mark se pata chal Raha hai ki doubt batate batate introduction batane Lage ge....😊
Sir if in 2 1 if we take f(-1) then it is one one or not
bro natural no. dont have -ve values
Thanks you sir❤️❤️ but while justifying 😥part is hard to understand 😭
Bhai kisko kisko exercise 1.2 ka question bahut hard lag raha hai
YOu just Helped an ARMY officer ....
Sir is type se banane par board number degi kya .btaye please sirrrr
❤
Thanks sri
👌👌👌👌👌👌👍👍👍👍👏👏👏👏👏
You are great sir 😍😍😍
Sir 1 doubt🧐
Part 5 may injective nhi hoga.
Kyu ki +1--------> 1 and -1--------> 1
So every unique domain , range is not unique.
Bro X³ hai toh (-1)³ = - 1. Hence it is injective function.
0:29 but sir agar justification puchh liya toh kya karenge.
Sir hamari taraf se aapke channel ko full support h 😊😊
Bro one video mai 1 ex complete video karo
Bina pdai 11th to krli abb kya hoga 😅
GyA
Sir muje diagram se samajh aata hai and easy ho jata hai , but mere class teacher condition lgaa kar karne se kehte hai 🥺😞 what I do for this??🥺😞 😢
Sir u are the best teacher in the world my all doubts are clear to see ur video pls sir send your no. If i have any doubt i'll inform u 👌👌nice explanation sir
2 ke 5 part mein kya kr dea apne...
osm sir 😇
Sir can we write these ans. in board
Sir aap apna face reveal kb karoge
Excellent
I am a jee aspirants and and I'm here for board preparation
It might be aspirant u mean
Good
Is this chapter more though than calculs
Sir humko samjh me toh sab kuch aaja raha hai but justify karne nahi aa raha hai. Matlab humko circle bana ke aur elements ke arrow diagram dekh ke yah to pata chal ja raha hai ki Kaun sa injective hai Kaun surjective hai, lekin humko ye F(x) = f(x) ye sab likha ke prove karne nahi aa raha hai. Ye sab likhna jaruri hai kya?
Sir isle first question ko dekh kar hi puura samajh mai aa gya your teaching method is great and you also sir Maine him aapko phone kiya tha
tq sir
Gjb sir👍👍👍👍
Sir is way me likhne se boards marks to dega na
How to answer through justification process
2 (v) me -1 or +1 ki image bhi to alag alag banegi sir apne ek hi dekha rakhi hai
Baki app bohot accha samjhate ho sir
Good ex a plan tion
Maja aa gaya sir
Aap unique ho
Sir thanks a lot
