# Coefficient ck of the fourier series

Luongo
1. find the complex fourier series and the real fourier series
f(t) = 0 , -pi <= t < 0, f(t)= t, 0<=t< pi

## Homework Equations

3. to find the coefficient ck i got 2 different answers one is if the index k is even and another if the index is odd, how am i supposed to represent this in the fourier series?

Hi Luongo!

(have a pi: π )

c2k = f(2k)

c2k+1 = g(2k+1)
