Learn how to convert a complex number from rectangular form to polar form. This video covers how to find the distance (r) and direction (theta) of the complex number on the complex plane, …

Review the different ways in which we can represent complex numbers: rectangular, polar, and exponential forms.

Consider the complex number 5 + 5 i . Which of these represents the same number in polar form?

Given a complex number in polar form, we can convert that number to rectangular form and plot it on the complex plane. Created by Sal Khan.

So what exactly is polar form? Is it the initial form from the beginning of the video?

Let's build off of our previous work with complex numbers and perform more sophisticated operations, like division. We'll also learn about a different and more visual way to represent …

Review the polar form of complex numbers, and use it to multiply, divide, and find powers of complex numbers.

If you're given these two, you can easily derive that one. And this one, which is just the Pythagorean Theorem, you're actually ready. You're fully equipped to convert between polar …

To make that a little clearer you could write it in the pure polar form where you have its magnitude out front. It's cosine of two over three pi plus i sine of two over three pi.
