Sir please NCERT exampler ki video bnadigiye ex 2.3 ke liye
sir domain or range par alg se video bna do ek kuch example ke sath
Sir in Q.2 ii) I think while finding range, y^2 > 0 => y > 0 and y < 0 we should take both conditions
Yes you are right
Square of anything gives postive number thats why y²>0
Same doubt y greater or smaller bhi ho sakta hai na wahi bola to kya hai kon wahi
Sir q2 me x agar 0 le y root9 aata yani y 3 bhi sakta y-3 bhi to 0 ke 2 image aa rahe to ye function kaise hua
Guys notice the sound of marker it gives a musical sound 😄😅...
No
@@smiledeepnirmaan4553 music is evrywhr.. U jst need to listen😇😊
@Aditya Verma ohh thnk god.... Kisi ne to music feel kiya 😄😄🤞🤞🤘
Sir kyaaa ho app mtlb shabd hi nhi hai mere pass❤❤ jab se app ki videos dekhni start aisa ek baar bhi nhi laga ki coaching jau sir ur videos are🔥🔥🔥🔥🔥🔥🔥
Sir second question ka second part me agar hum x ka value kuchh bhi rakhenge toh f(x) ka do value ata hai ek +ve aur ek -ve jabki fn mein ek preimage se do image nahi aa sakte. Sir is doubt ko clear kijiye
What about 1st part of Question 2nd???
Abe use solve nahi kar payega too?

Bhai mai ko bhee nhi smagh ma aya 2 no question
Maximum people jis Question me liye aaye the wahi Qus nahi hai 😛
Sir you don't understand me how to find the domain and range in real function clearly
Isse accha to subject teacher hai
Sir.. Cos²(xy)=cos(x)cos(y) likh sakte hai ki nahi plzz derive me..... Why not.....???
nahi likh sakte bhai
Sir aap ka teach krnye ka treka bhut he acha h thanku sir

Guys pls ish function ka domain batadho..🙏
domain is - (R-2)

Very nice explaining sir 👍
Bhai log 2nd question ka second part jinko samajh mein nhi aaya...darne ki koi baat nhi...kyu ki iss question mein chapter 6 (Linear inequalities) ka concept use hua hai...
Iss liye samajh mein na aana se gabrana mat...aur jab chapter 6 complete ho jayega...tab ye question bhi samajh mein aa jayega...
Thanks
Answer this question sir. If X = {1, 2, 3, . . . 10} and A = {1, 2, 3, 4, 5}, find the number of sets B ⊆ X such
that A − B = {4}
RAMPRABU S please explain the question corectly as mentioned in book. means what we need to calculate or find? whether no. of elements in B or what?
B={1,2,3,5}
Sir could you please explain this question again (range)

Huge respect to u Sir 🙏
same here bro
Sir ji live calass kitane se kitane taim chlate hai
Sir aapne 3rd unit pr nhi banai hai videos??
Nice
f(x)=√9-x²
The function is not defined when 9-x²
Aisa nhi ho sakta hai
Sir
Haa baat toh shai h

Basically, sir aap basically-basically bahut zyda use karte ho
Sir could u please deeply explain this question again
" IS EQUATION MAI AGAR AAP 'C' NAI NIKAL SAKTE TO MAI AAPKO KUCH NAI KEHNA CHAHUNGA" 😂😂😂😂😂😂😂😂😂😂😂😂😂
Sir plz ek baat clear kar dejeyea plz sir
Sir 11:03 me aapne bola ki x ,0 se barah hoga ya equal hoga par domain me toh x [ -3,3] tak hai
He is talking about the square of x and not of x, value of x can be -ve but value of x square can't be -ve.
Kyuki domain nikalte samay us condition ka zarurat nhi hai. Feel karo
@@JetPen shayad vaha feek ki jagah feel ana tha
@@RaghavSharma-yh6gc Sahi pakda yaar, sahi kar diya chal

Thanks a lot of sir during lockdown
Sir question no. 2nd ka 2nd part smjh nhi aaya dekho sir pehle aapne bola ki -3 to 3 domain hai mtlb hum x=0 put krr skte h aur jb hum x=0 put krte h toh f(x)=plus minus 3 aata h bt -3 is not in your range plzz explain sir
Same problem, 10:28par sir ne kaha √cannot be -ve.why? √9= +-3.plz reply sir
I have the same doubt.. when i solved range is coming to be between -3 and 3
