Converting Cartesian graphs into polar graphs

How do sine and cosine functions look in polar form?
Use the sliders on the left and button on the bottom to change your function, r = a + bsin(nx) or r = a + bcos(nx). From the Cartesian/rectangular graph on the left, see how the polar graph is plotted as you move along it (use the slider). Press Show negative r to see where negative r values are plotted once you have plotted the polar graph.
