Just in case you don't remember:
Given the polar coordinates of a point (r, theta) then it rectangular coordinates is (r cos theta, r sin theta).
---
Here:
r=5
theta=2pi/3=120 degrees
---
x=r+cos+theta+=+5+cos+120=5%28-1%2F2%29=-5%2F2
x+sin+theta+=+5+sin+120=5sqrt%283%29%2F2
So, the rectangular coordinates of the given point is:
(-5%2F2, 5sqrt%283%29%2F2)
