MATLAB Exercise on Fourier Series

Perform the following summation using the "for" loop structure:

seriessum $=\frac{8A}{{}^2}{\displaystyle \underset{n=\text{o}\text{d}\text{d}}{\overset{?}{}}}((-1{)}^{\frac{n-1}{2}})**\frac{1}{n^2}sin(2nt)$

Perform the summation for four different values of $n=1,2,3,100$ and plot all those results. The

result should look like as follows:
