Question

Two polar coordinates for the point (0,-3)

Plz answer asap. Many thanks =)

Answer 1

You need r and theta.

Make a drawing...no, just think of a drawing with the point (0,-3) ;)
Then ask yourself:
1. What is the distance from (0,-3) to O. This is r.
2. what is the angle from the positive x-axis to the half-line with endpoint O through (0, -3). This is theta.

Answer 2

i dont understand how do i get the coordinates though?

Answer 3

Answer 4
