Polar Test Review

Polar Test Review
No graphing calculators on this test, but you may have a scientific calculator.
Two parts to the test:
Part one: converting points and equations to and from polar and rectangular forms, plotting
points on a polar graph, determining symmetries of equations, and matching equations to
names of polar graphs.
Part two: graphing polar equations – you will be given a formula sheet for this part of the test.
Convert the rectangular coordinates to polar coordinates. Then give two other polar coordinate
representations of the point, one with r > 0 and the other with r < 0.
1. (1, 1)
2. (-10, 0)
3. (-3, 4)
4. (-2, 5)
5. (2, 2)
Plot each point whose polar coordinates are given, then find the rectangular coordinates for the point.
