Lesson Summary:

In this lesson, we learn about the standard form of complex numbers - A + Bi. We are taught how to find the values for the real and imaginary numbers given an equation. The rule that if two imaginary numbers are equal to each other, their real and imaginary parts must be equal as well is emphasized. By following this rule, we can solve equations and find the values for A and B.

Lesson Description:

Finding the values of real and imaginary numbers in standard form

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.
