Fourier Series. Writing a partial sum as an integral.

  1. Mar 12, 2013 #1
    1. The problem statement, all variables and given/known data

    Given: View attachment 56653 , show that this can be written as: View attachment 56651 .

    2. Relevant equations

    Hint: View attachment 56652

    3. The attempt at a solution

    Quite confused by this question. For f'N I have:

    [itex]\frac{4}{∏}[/itex]Ʃ[itex]\frac{cos((2n -1)x)}{(2n - 1)^{2}}[/itex] but i'm not sure where to go from here.

    I have read about the Dirichlet kernel, which is what I think I require, but I am rather lost.

    Any help is appreciated.

    Cheers.
