What Raphael means is that you should think of polar coordinates in terms of "pick a θ", plug it in, then solve for "r" instead of "pick an x value then solve for y". Unfortunately, there is not a good method of visualizing what a plot will look like in polar coordinates. Fortunately, you can plot in polar coordinates using a graphing calculator, if you have one. There are many tutorials online to show you how to do it for your specific model.
