Question 141787
 A circle centered at the point of origin has a radius of 10. If the point (10,0) is rotated 120 degrees counter-clockwise, determine the coordinates of the new point in exact radical form.
-------------------------
x = 10*cos(120)
y = 10*sin(120)
------------
{{{x = 10* (-1/2)}}}
{{{y = 10* sqrt(3)/2}}}
so the point is:
-5,{{{5*sqrt(3)}}}
