    1. The problem statement, all variables and given/known data

    Given this one period graph of a function with period 2pi,

    find a fourier expansion.


    2. Relevant equations



    3. The attempt at a solution

    So I was wondering if i can split up the integrals into two parts to find the coefficients. It is an even function so ak = 0.

    for bk can I split the integral as follows

    1/pi[int 0 to pi (x cos kx dx) + int pi to 2pi ((-x+2pi) cos kx dx]

    ?

    Yup, that's what you're supposed to do. Also, remember a0 isn't equal to 0.
