9. Polar Equations

For each pair of polar coordinates, (c) give the rectangular coordinates for the point. See Examples 1 and 2(a).

(4 , 3π/2)

Convert the point to polar coordinates.

$(0,5)$

For each pair of polar coordinates, (c) give the rectangular coordinates for the point. See Examples 1 and 2(a).

(1 , 45°)

For each pair of polar coordinates, (c) give the rectangular coordinates for the point. See Examples 1 and 2(a).
