Course: Trigonometry
Topic: Graphs of Trigonometric Functions
Subtopic: Combination Graphs

Overview

A combination function means combining functions together by adding, multiplying, or composing. In this lesson we graph combination trig functions and analyze them. This can be accomplished algebraically combining coordinates x by x. This is logically interesting, but I recommend using technology to produce the graphs instead so we can concentrate on analyzing the graph without the tedium of plotting it point by point. There is a lot to discover here, so have your grapher at hand!
