Math (Trig)

Suppose the point A is on a circle of radius 6 with an angle of 240 degrees. Find the value of the coordinates of this point. Round your results to 3 decimal places.

So in this case,
x=rcos(theta)
y=rsin(theta)

x=6cos(240)
y=6sin(240)

Rounding to 3 decimal places:
x=-3
y=-5.196

Is this correct?
