20th wala btw
cosx+sinx is (sqrt(1+sin2x))
then just differentiate by l hospital
so bina l hospital ke nhi ho payega
hmm
sad
let me think wait
kuch ho sakta
l hospital is fire tho idk y u don't prefer it
Backlog šš»šš»
maybe take sqrt(2) common in Dr and write (1-sin2x) as (cosx-sinx) and then maybe split the Nr
but other than that idk what else u would do
differentiation is important bhai
u need it for every calculus chapter
continuity se pehle pura kar luga
Promise
jo sahi dikhe karlo ig
that should be first priority
Maine root 2 common leke kiya tha
Then cos(a-b)
Kardiya
cos(a+b) kaha se aaya
Ye dekho
Isse aya nhi
L hospital hi sikhunga ab
thanks
i meant cos(a-b)
btw
sorry for confusion
Jaldi jaldi me likh diya
cos(x-Ļ/4) is not cosx bro š¤²
yeah ig
can't simplify further
unless binomial theorem but that is too tedious
are bhai wo 'h' hai
x nhi
oh no
x-Ļ/4 ko h likh diya tha
alr then fine
jisse h tends to 0
Hojaye
understood gng
ye isse aage nhi ho raha
L hospital karlo pls š¤² š¤² š¤²
not learning it is just inconvenient
yeah wahi karna padega
Thanks for the help bhai

you can do limits questions in seconds
Wait what?
ok u help
Not necessary ki uske bina na ho ig.
wsg bro
give ideas
binomial is possible sure but that will take too much time
Bhai meri writing itni buri hai kya šš
board pe esi hi hojati hai
aap batado bro
.
Yaha tak kiya hai
Root2 common lekar cosa-b laga diya
aur x-pie/4 ko h likh diya
Tab bhi 0/0 ban rha hai
Is the answer 14?
Correct
1-cos7h solve nhi kar paya mai
Thank you bhai
Ye wala formula kese bhul gaya
