Problem 1
Here is a graph of a trigonometric function. Which equation could define this function?
\(y = 1.5\sin(x) - 4\)
\(y = 1.5\cos(x) - 4\)

Here is a graph of a trigonometric function. Which equation could define this function?
\(y = 1.5\sin(x) - 4\)
\(y = 1.5\cos(x) - 4\)
\(y = \text-4\sin(1.5x)\)
\(y = \text-4\cos(1.5x)\)
Sketch a graph of \(a(\theta) = \cos(3\theta)\).
Compare the graph of \(a\) to the graph of \(b(\theta)=\cos(\theta)\). How are the two graphs alike? How are they different?
Here is a point at the tip of a windmill blade. The center of the windmill is 6 feet off the ground and the blades are 1.5 feet long.
Write an equation giving the height, \(h\), of point \(P\) after the windmill blade rotates by an angle of \(a\). Point \(P\) is currently rotated \(\frac{\pi}{4}\) radian from the point directly to the right of the center of the windmill.
The coordinates of \(P\) are \((1,0)\).
