i was thinking breaking the integral into -1 to 0 and 0 to 1
since |x|= -x for x<0
both the integrals would cancel out
so integral =0
Why it would cancel out ??
If x is between -1 to 0, the function would be x ( 1 - x + x2/2 - x3/3 + .... + x4050/4050 )
To that is a whole different function
Haan kuch terms cancel ho jaenge if we take x common
Par pura cancel nahi hoga
if x is between -1 to 0 |x|= -x , not x
andar wali cheez toh same rhegi
Basically odd wali powers ke terms zero ho jayenge (odd functions). Even wale terms ko 0 se 1 integrate karo to get integrat of sum of x^(2n+1)/2n
Integrate karne pe you get something like sum of 1/4n(n+1)
And then just telescope that
After that multiply by 2 to get answer.
By applying kings rule ??
This is wrong ???
yooo??
Matlab yeah odd function ka -a se a integral is zero. (Idk what math rules are called ;_;)
Yep. Even powers wale terms are even not odd, so they don't get cancelled.
can u confirm what i said first
wait ill write and send
acha got my error
ill look at your method now
ho gya thanx
