1. 9.3 Polar and Rectangular Coordinates

2. The following relationships exist between Polar Coordinates (r,  ) and Rectangular Coordinates (x, y): Polar vs. Rectangular Forms

3. Rewrite the following polar coordinates in rectangular form: Polar vs. Rectangular Forms

4. Now, rewrite the following rectangular coordinates in polar form: (5, 5). Polar vs. Rectangular Forms

5. An equation whose variables are polar coordinates is called a polar equation. The graph of a polar equation consists of all points whose polar coordinates satisfy the equation.

6. Identify and graph the equation: r = 2 Circle with center at the pole and radius 2.

12. is a horizontal line a units above the pole if a > 0 and units below the pole if a < 0.

13. is a vertical line a units to the right of the pole if a > 0 and units to the left of the pole if a < 0.
