Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.Not a standard method, but this works.
Now that you have f(x), its fairly simple to find f'(x) ig
Bro how did you even thought of this method
Like its a bit lengthy for exam but still
I thought of approaching this algebraicly first.
Since we are asked relating to f(2) and f(4), we can make a first order linear recurrence in even numbers. (Meaning a functional equation of type a(x+1)=f(x+1)a(x)+g(x), the solution to which is pretty standard)
The answer isnt matching
Im getting f'(4)/f'(2) = 10
Yea my bad. g(2) is not 3 but 3/4
I'll recheck the Calc, though the method is correct.
Can we do using partial differentiation
Yes, we can ig.
I tried using partial diff
Kaafi chota hogya solution
Or u can find the function usse bhi kaafi easy hojega
bhejna
Send pls
wait
i dont have my phone rn
when i get it i will send
abhi phone milna thoda muskil ha
i can tell how to find fx
in the given eqn, put x as y and y as x
then equate both
and put y=2 as we are given f2 = 3
fx aajega
bro cooked hard 🔥
ans kya dia hai
f(x) yeh hai na
mera 248 aa rha
LESGO
yahi ha
send soln pls
meine first principle se try kra
56 aa rha 🤡
did exactly what he said
didnt even need partial differentiation
how do u use that effectively...i just circle round and round into oblivion
Rough but u get the idea
should i close this?
yep
