Complex Numbers Ex 4C & 4D

As we have already seen, Complex Numbers can be in Cartesian form using the general equation z = a + bi. We can also write Complex numbers in what is called the modulus-argument (or polar) form. Below are the links to a four part tutorial explaining:

How do you convert a complex number in Cartesian form to polar form? How do you add, subtract, multiply and divide complex numbers in polar (modulus-argument) form? What is De Moivre’s Theorem? How does it apply to complex numbers?

Complete solutions for Ex 4C and 4D have been posted on the Specialist Maths Wiki.
