A complex number in the form: z = a + bi can be written in polar form as: z = r.e^{i.theta}, where r = √(a^{2} + b^{2}) and theta = tan^{-1}(b/a) (that's arctan(b/a))

You should plug your numbers into these.

I notice the polar form sometimes seems to be written as r.cis(theta) which is r.cos(theta) + i.r.sin(theta) (which I think is more like rectangular form!!).
