Sine Cosine Graphing

The 4 key features that we'll use for sine/cosine graphs are

M: ​ (a)   ​

A: ​ (b)  

P: ​ (c)  

PS:​ (d)  

• midline

• amplitude

• period

• phase shift

What is the equation of the graph?

•  y = 2 cos x

• y = sin x

• y = 2 sin x

• y = sin 2x 

Where does the graph of y=sin(x) begin its first cycle?

• (0,0)

• (a,0)

The period of a function is

• the length of one cycle

• how high and low the function goes from the center line

• the range of the function

What is the equation of the graph?

• y = 2 cos θ

• y = sin θ

• y = 2 sin θ

• y = sin 2θ

• A
• B
• C
• D
