Question

Find the rectangular coordinates of the point with the polar coordinates (3, 3/2 pi).

Answer 1

(0, 3)

(0, -3)

(-3, 0)

(3, 0)

Answer 2

Let (X,Y) be the rectangular coordinate. And let \[(r, \theta)\] be the polar coordinate.

X = r*cos(theta)
Y = r*sin(theta)

Answer 3

can you walk me through it? I don't really understand

Answer 4

Ok, let's look at the given coordinate. (3, 3pi/2)
This means a point exists 3 units away from the origin (0,0) in the direction of the angle 3pi/2.
