Essentially, a question reads: Graph the polar curve r = 4cos(2?), where ? is a radian angle.

The graph of the curve looks like a 4 leafed clover.

The following function, r=3cos(?), looks like a circle centered at (3/2, 0).

You can use the polar_plot() function as follows:

sage: polar_plot(3*cos(2*x), (x, 0, 2*pi))


sage: polar_plot(3*cos(x), (x, 0, 2*pi)


sage: polar_plot?

for more deatils. Also, note that polar_plot(XXX) is just a shortcut for plot(XXX, polar=True).
