Homework Help: Fourier series odd and even functions

  1. Jun 17, 2012 #1
    1. The problem statement, all variables and given/known data


    3. The attempt at a solution

    I don't understand the step above. It has something to do with this equation


    I think. I'm supposed to expand it into an appropriate fourier series.

    You haven't given us enough information. What is f(x)? You were probably given a function and asked to expand it in a sine series.

    The "step above" is just applying the definition of the Fourier series:
    Are you saying you do not know what that is?

    here is some more info




    I don't understand why they're adding the sin on to that last step.
