This topic covers: - Unit circle definition of trig functions - Trig identities - Graphs of sinusoidal & trigonometric functions - Inverse trig functions & solving trig equations - Modeling with trig …

In this video, I want to give you the basics of trigonometry. And it sounds like a very complicated topic, but you're going to see that it's really just the study of the ratios of sides of triangles.

Can you find the length of a missing side of a right triangle? You most likely can: if you are given two side lengths you can use the Pythagorean Theorem to find the third one. But, what if you …

You can start anywhere, use only the required amount of trig functions, or use trig functions to find out everything: all that matters is you choose where to start, and use the right functions from …

Review the unit circle definition of the trigonometric functions.
