Set up a table of 'y' and 't' values and calculate the values from #0 to 720# (or #0 to 4pi#) in the expression. Plot the pairs of numbers on a graph paper or use a computer program.


This example produces this curve for ONE cycle:

To make a graph for two cycles, just copy this one on to the end of it. (or generate another set of values)
