Video about finding the equation of a trigonometric function from its graph. Two examples are sine functions and one example is a cosine function [9:52]

Video showing how to graph the sine and cosine functions from their equations with modifications to the amplitude and period. Also gives an example of determining the trigonometric function using the features of the graph. Includes link...

In the world of calculus, pre-calculus, and trigonometry, you will often find references toward and problems regarding "the unit circle." But, oddly, we are rarely ever taught what it is! This video will change that with an in-depth...
