Question

How do you convert the polar coordinate (1, 150°) into cartesian coordinates?

Answer 1

`color(magenta)("Cartesian coordinates " (x, y) = (-sqrt3/2, 1/2)`

Explanation:

`(r, theta) = (1, 150^@)`

`x = r cos theta = 1 * cos 150 = -sqrt3/2 ~~ -0.866`

`y = r sin theta = 1 * sin 150 = 1/2`
