Question 1 of 3

The graph shows one complete cycle of a cosine function. What is the amplitude of this function?

Question 2 of 3

The graph shows one complete cycle of y = a·sin(bx). The amplitude is 3 and the period is π. Find the value of b.

Question 3 of 3

The graph shows one complete cycle of y = A sin(Bx) starting at the origin. If the amplitude is 3 and the period is π, what is the value of B?

How this fits in

Graphs of sine and cosine is one skill in the Trigonometry unit. Students read the unit lesson, then earn a bronze, silver, or gold medal on their last 10 answers. Medals never go down. A mastered unit comes back for review after 1, 3, 7, 16, and 35 days so it stays learned.
