    we gotta test for symmetry... about polar axis... change the theta to -theta...

    about the vertical line theta = pi/2, change theta to pi-theta

    Pi/theta? Or pi minus theta?

    for the last one, change theta to pi-theta this checks for symmetry about the vetical line through the pole.

    cosine is even so cos(theta) = cos(-theta)
