(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

So, on a Fourier Series problem I came up with

2/3 + (8/π^{2})∑(1/n^{2})(-1)^{n}cos(^{nπx}/_{2})

I'm supposed toPlot s_{m}(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.
