	<p>A little example of how <b style="color: blue;">sine</b> and <b style="color: red;">cosine</b> combine to draw a circle.
	<p>The <b style="color: blue;">blue</b> line shows a <b style="color: blue;">sine</b> wave travelling along the x axis. For values of <i>i</i> between 0 and <abbr title="this is Tau, which = 2π">τ</abbr>, the wave starts from the bottom of the canvas before sweeping up to the top and then back down.

	<p>The <b style="color: red;">red</b> line shows how (for the same values of i, and when plotted on a vertical instead of a horizontal axis) a cosine wave does not start at the edge of the canvas, but instead starts in the middle, so it sweeps right then left, before return to the middle.
