Summary
Symmetric and asymmetric periodic waveforms, with one half of a cycle ghosted and flipped to show the difference. The red is symmetric and green is asymmetric.

Red is:


 * $$f(t) = \cos(t) + \cos(3t+1) + 0.2\cdot \cos(7t+5)$$

Green is:


 * $$f(t) = \cos(t) + \cos(2t+1) + 0.2\cdot \cos(6t+5)$$
