zw = (r_1 *r_2)(cos(theta_1 +theta_2) + isin(theta_1 +theta_2))

Explanation:

Alright, so the polar form of a complex number z=a+bi is

z= r(cos(theta) + isin(theta))

Suppose you have a complex number w which you wanted to multiply by z, then this will be the rule you need to use

zw = (r_1 *r_2)(cos(theta_1 +theta_2) + isin(theta_1 +theta_2))
