Homework Help: Need to do a summation

  1. May 16, 2010 #1
    1. The problem statement, all variables and given/known data

    So, on a Fourier Series problem I came up with

    2/3 + (8/π2)∑(1/n2)(-1)ncos(nπx/2)

    I'm supposed to Plot sm(x) versus x for m= 5, 10, 20

    (m is the index of the summation, which starts at m=1)



    2. Relevant equations

    meh


    3. The attempt at a solution

    The problem is that I don't have a computer program to do this. So I was wondering if someone could give me a link to a site that would do this.
