# Quiz #4

Question #1: Do the calculation on the board. Include this calculation at the top of your document. Let the two values that you get in your calculations be a1 and a2. If a2 is 0 then you will work on the red region, if a2 is 1 you will work on the green region, if a2 is 2 you will work on the blue region.

Question #2: Graph the equation (not filled) of $r = 2+4 cos(3(\theta+\pi/8))+sin(8\theta)^2-sin(a_1 \theta)/2$ and show that it looks something like the graph above. You may find an extra small loop at the origin, but try to ignore it. Graph only your region (again, not filled) make the inner loop green and the outer loop blue.

Question #3: Find the area of the region between the outer loop and the inner loop (only on the region determined by a2).

Question #3: Find the length of the outer loop and the length of the inner loop (only on the region determined by a2).
