# Graphing transformations of trigonometric functions - Graphing Trigonometric Functions

### Graphing transformations of trigonometric functions

After learning all the graphs of basic trigonometric functions, in this lesson, we are going to go a little bit further on how the graphs will be transformed as the functions change. The general form for the equation of trig functions is y = f [B(x + c)] + D, where f refers the trig function; A refers to the amplitude/steepness; B represents the period of the graph; C refers to phase shift (left or right) and D represents vertical shift (up or down). We will learn how to graph the trig function for multiple periods; state the vertical displacement, phase shift, period and amplitude; and also find the domain and range of the transformed functions.

#### Lessons

##### For each trigonometric function: (i) Graph the trigonometric function for one period. (ii) State the vertical displacement, phase shift, period, and amplitude. (iii) State the domain and the range.
