Lesson Description:

Graphing a trig function with cosine

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.

Questions answered by this video:
  • How do you graph a cosine function?

    Live classroom session covering an example of how to graph a cosine graph over two periods. The teacher explains the meaning and how to calculate period and amplitude of a trig function. The teacher shows how to find x-intercepts to help find "critical points" to help draw the graph.
