Question

Find the rectangular coordinates of the point with the polar coordinates (1, 1 divided by 2 pi).

(0, -1)
(1, 0)
(0, 1)
(-1, 0)

Answer 1

hmm I wonder what point that is equivalent to in Cartesian form

Answer 2

x = r cos theta, y = r sin theta
Here, r = 1 and theta = (1/2 ) pi
x = 1 cos (pi/2), y = 1 sin (pi/2)
= 0, y =1
(0,1)
