Help me solve a Fourier series question

[shermaine]

Hi guys,

I need help to solve this fourier series question.
I'm pretty confused when there is a period of L.Can anyone one kindly advise me how to solve this question. Thanks a million.
The perioddic square wave f(t) = { 0 -T/2 < t < 0
A 0<x<T/2

for f(t + T) = f(t).
Find f(t) and an and bn for A = 250/ I +100 and T = 1/f = 1/10I
and N = 1,2,3....8 on time interval of 0<=t<=3T.
Please advise me. Thanks.

some error with the q
here is it

Hi,

Here's the correct q:

The perioddic square wave f(t) = { A/2 -T/2 < t < 0
-A/2 0< x < t/2
for f(t + T) = f(t).
Find f(t) and an and bn for A = 250/ I +100 and T = 1/f = 1/10I
and N = 1,2,3....8 on time interval of 0<=t<=3T.
Please advise me. Thanks.
