Graph a Lemniscate of the form by first graphing the rectangular graph . You can drag point with the mouse and the points on the polar graph will move with it. Note that the rectangular graph is not exactly the corresponding function. In order to get the radius for the polar function, we need to take , which, if will yield an imaginary number. This means that there will be nothing on the polar graph, as we cannot use an imaginary radius.
