#### Answer

The wave will approach the shape of the square wave.

#### Work Step by Step

This problem involves Fourier series, so most graphing calculators will not work. Rather, it is necessary to use a Fourier series plotter or to create one by yourself (with a program such as MATLAB). What you will see is that the more points that you plot, the more the graph will resemble the square function. When you plot only 3 terms, it is only a slight resemblance, but when you plot 10 terms, the resemblance will become more noticeable. If you try 100 terms, the two shapes should look very similar.
