Lesson Summary:

This lesson provides an overview of complex numbers, explaining the structure of a complex number as a real part plus an imaginary part, and the importance of the real and imaginary parts being equal for two complex numbers to be equal. It also delves into the concept of i as the square root of negative one and how to rationalize the denominator when it involves i. Additionally, it demonstrates the usefulness of conjugate pairs of imaginary numbers when eliminating i from a denominator.

Lesson Description:

Overview of complex numbers

I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.

There was a mistake in a+bi+c+di =>(a+b)+(b+d)i It should be (a+c)+(b+d)i
