Question

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

Answer 1

(3, (3/2)pi ) signifies (r, theta). In other words, the radius, r, is 3, and the angle, theta, is (3/2)pi.

The appropriate conversion factors are as follows:

x=rcos theta
y=r sin theta

Answer 2

Use them to find x and y, and then write the solution as a point: (x, y)
