Answer 1

It says prove theorems for the product and quotient of two complex numbers using Eulers identities which is e^ix=cosx+isinx

Answer 2

hint: use law of exponents for the following:
\[\frac{r_1 e^{i \theta_1}}{r_2 e^{i \theta_2}} \\ \text{ and } (r_1 e^{i \theta_1}) \cdot (r_2 e^{i \theta_2})\]

Answer 3

Yes so far for my proof I have :
