7.2.1 How can I transform a sine graph?
Transformations of y=sin.x
In Chapter 2, you developed expertise in investigating functions and transforming parent graphs. In this
section, you will investigate families of trigonometric functions and their transformations. By the end of this
section, you will be able to graph any sine or cosine equation and write the equation of any sine or cosine
graph.
7-113. As you have seen with many functions in this and other courses, x is generally used to represent an
input and y is used to represent the corresponding output. By this convention, trigonometric functions should
be written y = sin x, y = cos x and y = tan x. But beware! Something funny is happening.
With your team, examine the unit circle and the three graphs below. What do x and y represent in the unit
circle? What do they represent in each of the graphs? Discuss this with your team and be prepared to share
your ideas with the class.
7-115. Sketch a graph of at least one cycle of
y = sin x. Label the intercepts. Then work with your team to complete parts (a) through (c) below.
