As is the case with most subjects in mathematics, we desire a visual approach to this subject. Indeed, it would be nice to be able to draw the graphs of the functions we have been studying.
A preliminary study of this begins with simply plotting some of the points and ``connecting the dots.'' If one goes through this exercise, the task of drawing these curves is fairly straightforward. In order to accomplish, recall the following values of the trig functions:
