Question

Write z = -3i in polar form​

Answer 1

The angle θ between the positive real axis and the ray containing z whose endpoint is the origin is called the argument of z, and is equal to arctan( ). The polar form of a complex number z = a + bı is this: z = r(cos(θ) + ısin(θ)), where r = | z| and θ is the argument of z.
