Is that supposed to be (4, -/6)?

If so, you would use this formula:

x = rcosӨ

y = rsinӨ

x = 4cos(-/6)

y = 4sin(-/6)

-/6 on the unit circle is the same as 11/6. The cosine (or x-value) for this angle is 3/2, and the sine (or y-value) for this angle is -1/2.

x = 4(3/2)

y = 4(-1/2)

x = 23

y = -2

Your answer is:

(23, -2)
