Sir but in the last step when we have to prove on to function you wrote real is not equal to natural where real number is range and natural number is codomain but according to the diagram Domain is natural number not codomain. codomain will also be same as range then. sir please explain
Mereko bhi ye nhi samaj aya
All the values.of codomain are natural no. Since they range bt 1-2
Hindi main likho babua
Muje bhii samj nii Aya here the function is onto 👀
Mujhe bhinhi aya

Your explanation is so good sir. Thankyou so much sir 🙏🙏🙏🙏🙏🙏
Sir ye video ek baar aap khud dekho ,.apko bhi samjh nhi aayega

Kal Se Padhogaa 🥲👍🏻👍🏻👍🏻
Q Bhai???😮💨
Nhi mat padh koi jarurat nhi hai teri yaha pe
Very useful video Thanks Nexa classes👍👏
Phele me jab one- one prove karna tha toh f(y) = 1/y but jab onto prove karna tha toh f(y) = 1/x likha aisa kyu .🧐🧐
Bhai question me 1/x Diya isiliye one-one ke liye 1/y use Kiya f(x)=f(y) or f(x)≠f(y)
Onto me f(x)= y aata hai isliye f(y)=1/x
Uper se paar ho gaya 😢
Kahi tution lagva phir
at the last of the video, sir said co domain has natural values...but actually domain has natural values..right?
For this doubt itself I opened the comment section
Maybe misspelled
@@rezwanbhuyan1063kya ya doubt clear hua..?
Agr hua to explain plzzz
@@Vikrant777... sir ne galti s bol diya tha

Mujhe bhi .
Very nice explanation 😀👍
Kafi time consuming explaination thi
Sir, 11:45 pr check karo
Range me real number to theek h
Pr co domai me bhi to real number h natural number nhi h
Yes bro
Same doubt
Ur correct!...he meant to say ki range are natural values aur co domain is a real value!...he just misplaced the words!..the solution is anyway correct!..

But sir co- domain bhi toh real value hi show karega only domain hi natural value dega
Sahi kaha

Thanku you sir 😁 I think you are the best teacher in the world 😀
Really your are such a good teacher sir . Aap mere liye best teacher hote but vo upadhi me aapne school ke teacher Rajiv sir ko de chuki hu .. But your explanation way is very nice and easy for students.. 🙏🙏
Very nice explanation sir so thanku so much sir 😊😊
Very very helpful vedio sir ji
Thanks
Thanks sir ache se samajh aa gaya 😇😇😇😇🙂🙂🤩🤩
I am very happy to see your teaching sir
Thanks you so much nice video 👌👌
Thank you so much sir ❤🙇
Gjb ke explanation karte ho AAP sir
Pura concept samjh me aa jaata h so jao ho nexa classes
Very good sir bot acha se samaj me aa geya h ji
9:00 yaha per sir app ne f(x) ko f(y) se replace kiya hai lekin image of xis equal to y hai
Do of su
Sir plzz apse request hai ek baar aap khud is video ko dekh ke samjho kya apne sahi btaya pehle aap bolte ho range =co domain hai phir dusre part me mana kar dete ho
Very nice
Esme gelet h ek last ka step jisme range is equal to real numbers nehi range is equat to rational numbers hoga kyoki natural no ka 1/x rational hi ayega sirf real number nehi ayega to rational or real equal nehi hoga ..
Kuch nai samaj ayya 😢
Nhi aage khud ko to kuch aata hai

सर आपने जब आर स्टार की रिप्लेस पर नेचुरल नंबर लिया तू ऑन टू ऑन फंक्शन निकालते समय डोमेन को कोडोमेन बोल रहे हैं आप
Yes
Yes
Yes
And it is onto
Hm dhokhe se muh se nikal gya
Function is not onto
Codomain me 4 aayega kyuki codomain R* hai
Aur agar codomain 4 hoga to domain 1/4 hona chahiye jo ki NATURAL NUMBER nahi hai
So 4 in codomain has not preimage in domain,therefore function is not onto
Ty sir very nice explanation
8:36 Ngl, if here is a new student of Grade 12, I'm sorry to scare you by telling already, Chapter 6 and 7 are a nightmare, You'll cry out till the ending of chapter 6 and the worst is yet to come, Chapter 7, Integration
its easy
it needs practice , if you are thinking to do it before exam then you are not more than an idiot
@@lowendmania9332 I do agree entire maths of 12th is easy but the variety of questions you can be asked and not a very well defined syllabus is the problem ngl
At 7:50 how we put f(y)=1/x. ??
Fx is equal to y
I have same doubt 🧐
Agar youtube ek school hai to sir yha ke bachho ke sbse favourite means best maths teacher hai
😊😊
Thank you so much sir i love your teaching ❤❤
Sir Domain is Natural numbers, Codomain and range are real number. At 11:30. Not able to understand your explaination
Jeh reply nhi karta
Same confusion
Sir, range less than equal to co domain , there for range is natural number and co domain is real number.
Good morning sir ......ur all videos are very helpful to us......plz repeat the question 1 at last onto function.......real not equal to natural Numbers,.....,
Sir apne introduction me bola ki co-domain woh he jo image banne ke pehele ka present all the no. in y hey toh onto ka part meh apne co-domain ko domain ke no.Le liya introduction ke hisap se to range or co-domain hamesha equal honna chahiyeh nah?
maina bhi yahi question hai
Same confusion here, 😢
hi apke pass physics hai kesa gaya apka@@xerxes._o4
Sir isme co domain to complete set of B hai ,
Dil se sukuriya guru ji 🙏
sir first set is domain , how its codomain ?????
pls reply if anyone knows
Yes first set is domain its was a small mistake but in the ans range nt equal to co domain as there are many real numbers for which image is not formed...
Simple tip for all students who are struggling in understanding how to find one and onto :
• For one one, prove that
f(x1) = f(x2)
x1 = x2
• For onto, prove that
f(x)=y
Thanks sir ❤❤❤
Sir I am in 11th but i am easily able to understand 12th questions 🙂😛🤧
Phele boards ki exam to delo

Nice
One-one prove karne ke liye f(y)= 1/y ho gya par onto prove karne ke liye f(y)=1/x hi kyu reh gya.....koi samjhayega ?
Haa bhai, same mujhe bhi nhi samjh aaya 😢
Thank you so much sir 😊
Thank you sir
Thanks for nexa classes 1🙏
You are vary best teacher sir and is very nice cvalification but may mind is very fast so next exerci se so come to the next exercise ,video thank you sir i have a nice day your may best teacher for nexxa classes but may teacher is very bast may teacher name pawan sir math lacturara is bast teacher
11:44 range = co-domain..... real = natural number aapne domain ko co-domain kyu kaha?
Kyuki isko khud ko bhi nhi aata h isliye 😅. NCERT solutions m Jo likha rehta h ushiko ko dekh dekh k sikha ta h. 😂
Tq so much sir 🙏🙏🙏
Sir co domain to right side waali hoti hai naa to usme to N no. Ni hai R no. Hai
Ye to domain ko hi co domain bta rhe h
kal mera exam hain sir apki waja sai mnai sara math pada ❤
I am not at all confused in this chapter just because of you sir ❤️🙏

Sir aap case study ki bhi video bna do
Thanku sir
Correction-Sir last mai co-domain toh real number hogi... Or range +ve real number hogii..
Sab samajh aa gaya thank you nice explain sir ❤❤❤
Sir please use cello gripper pen for clear visible

Bhai vo akela hi hai
😂@@abhrankamboj
Correction for 2nd condition,
Rational =|= Real
Because range would be rational numbers and co-domain Is the set of real numbers.
Bro, real numbers include rational numbers. 💀
I know real numbers include rational numbers but real numbers are not equal to natural..🗿.. for this i meant that where sir has written " Real =|= N" , we should replace it with "Rational =|= Real"
Bcz here the range would be only Rational numbers but the co domain is still real.. and rational is not equal to real... Hope you will understand...❤
@@SpreadIslam982 In that case, your correction is not precisely correct. The range encompasses all positive rational numbers. Therefore, the correction should be that since positive rational numbers don't constitute the entirety of the codomain R (or, since the function only maps to positive rational numbers), the function is not surjective when f:N->R.
elements ke bhi solution do sir 🙏🏻
11:38 sir range codomain ke equal ho to rha tha, both are real number, left side is domain not codomain.
Range codomain ke equal nahi hai kyuki codomain ke real values Range ke equal nahi hogi.. Example ✓6 real value hai but ye condition ke hisaab se range ke equal nahi h isliye ye onto nahi hoga..
Nice teaching sir i like your video
Sir Domain h Natural number pr aapne co - domain bna diya
Smj nhi a raha kuch sir 😢😢
Sir 2nd condition me jo aap co-domain ko natural number liye hai ,co-domain to complete set B hota hai jo ki real no hai
Diagram me ta f(x) is not= f(y) so, x =y how it is possible
Sir your explanation is good but this chapter have no logical reasoning
Sir please phir se

Good explanation
Very helpful video . 😊

Sir vo to domain h na jise aap codomain bta rhe ho introduction me btaya tha na aapnr
This is tough some some.
F(y) 1/x kiu 1/y kiu nahi sir ?
Thanks 🙏 you so much sir teaching
Thnx sir 😊
I think sir aapko co domain ki jgh domain likhna tha
Sir aapne
One one Mein
Y= 1/y put kiya hai..!!
Aur
Onto mein
Y= 1/x
Put kiya..!!
Sir aisa kyu..??
