Sample Chapter (first three LO's)

Periodic Functions

Graphs of Sine and Cosine Functions

Learning Objectives

• Find amplitudes, periods, and any phase shifts (horizontal translations) of given sine or cosine functions

• Use transformations to graph functions involving sine and cosine

• Graph trigonometric functions that have amplitudes other than one (vertically stretched or compressed)

• Graph trigonometric functions that have stretched or compressed periods

• Write equations of graphed trigonometric functions
