1. Match the graph to the correct equation: i. 2 sin( x)
GRAPHING TRANSFORMATIONS OF SINE AND COSINE
1. Match the graph to the correct equation:
i. 2 sin( π2 x)
ii. −2 sin( 21 x)
iii. 2 sin( 12 x)
iv. 2 cos( 12 x)
v. 2 cos( π2 x)
vi. −2 cos( 12 x).

2. For the sinusoidal graph below write two equations, one of the form A sin(ωx − φ) + B and the
other of the form A cos(ωx − φ) + B.
3. For the sinusoidal graph below write two equations, one of the form A sin(ωx − φ) + B and the
other of the form A cos(ωx − φ) + B.
4. Graph two cycles of f (x) = 2 cos(3x + π2 ) − 1 and label the five key points (in each cycle) described
in the graph summary.
