			Plot <math> \ \frac{2}{T} \sum_{n=1}^\infty sin\bigg(\frac{2 \pi nt}{T}\bigg) \!</math><br><br>

			While we can't sum to infinity in the computer, we can get a close approximation summing over a large enough range of <math> n \!</math><br>

			I found summing over <math> n = 1:1000 \!</math> was about the most the computer could handle reasonably.<br>
