Imagine an arm where one end is pinned at the centre of a circular style graph and at the other end is a pencil. Also, the length of this arm can change such that its length is governed by a formula involving the angle of rotation.

Suppose the length of the arm is #r# and we had one equation that was #r=5sintheta# and a second where #r=5sin(3theta)#

Then we would have:

If you so chose you could graph it on standard graph paper. In which case it would look like:
