Question

Determine two pairs of polar coordinates for the point (3, -3) with 0° ≤ θ < 360°.

Answer 1

plot the point, and find the distance from the (0,0) to the point (for r)
and the angle using \(\tan^{-1} y/x \)

Answer 2

the "other coordinate pair" is to add 180 degrees to the angle and then multiply r by -1

Answer 3

is it (3 square root of 2, 225°), (-3 square root of 2, 45°)
