**5. About Multiplying & Dividing in Polar Form
**

For a more detailed explanation, please first read the Theory Guides above.

Polar form is writing complex numbers in a different way.

z = x + iy can also be written as:

z = rcosΘ + irsinΘ

z = r(cosΘ + isinΘ) is referred to as the **polar form** of z

.

**Multiplying Two Complex Numbers in Polar Form**

- Step 1 – Multiply the modulii
- Step 2 – Add the arguments

.

**Dividing Two Complex Numbers in Polar Form**

- Step 1 – Divide the modulii
- Step 2 – Subtract the arguments

.
