9. Polar Equations

Convert the point to rectangular coordinates.

$(-2,-\frac{\pi}{4})$

Convert the point to rectangular coordinates.

$(4,\frac{\pi}{6})$

Convert the point to rectangular coordinates.

$(-3,0)$

Convert the point to rectangular coordinates.

$(0,\frac{7\pi}{4})$

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).

(3 , 120°)

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

(5 , ―60°)

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

(―3 , ―210°)
