Find the rectangular coordinates of the point with the polar coordinates (8, 3/2pi)
How do you do this?

Answer 1

polar (r, theta) to rectangular (x,y):
x = radius×cos(theta)
y = radius×sin(theta)

Answer 2

can you walk me through it? I'm new to polar cord. @DDCamp

Answer 3

Yeah, no problem.

Answer 4

would it be (0,-8)?

Answer 5

Normal (rectangular) coordinates give you a length along 2 axis (x and y):


But when you're given a polar coordinate, you have two parts, the radius from the center (r) and the angle (theta):
