Staff Review
This lesson shows more examples of graphing trig functions. Also, you will learn how to find the amplitude and period of trig functions. It is usually easiest to graph the parent function, such as cos x or sin x, and then modify it based on the coefficients. This is a great place to learn or review how to graph trig functions.
