Verbal: Related Vocabulary Periodic function is a function whose values repeat at regular intervals.
Cycle the part of the graph from any one point to the point where the graph starts to repeat.
Unit 2 - (3) Intro Sine & Cosine
Period is the difference between the horizontal coordinates corresponding to one cycle. (How long does it take the function to start repeating.)
The parent function, the function without any transformations, of sine and cosine has a period of 360 degrees.
Numeric Do not copy. Follow the directions to create a drawing. 1. Draw a first quadrant angle in standard position. Label the terminal side r. 2. Label the initial side x. 3. Draw a line from the terminal side to the horizontal axis. Label that line y. That is called a reference triangle.

Algebraic The function f is a periodic function if and only if there is a number p for which f(x-p)=f(p)
Using that triangle write the value of

How do they relate to what you already know about those function? Now let's take a look at the drawing and discuss what is happening to the graph and how it relates to the coordinate plane.
