Question 141712: A circle centered at the origin has a radius of 6sqrt2. If the point(6sqrt2,0) is rotated 45 degrees clockwise, determine the coordinates of the new point. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! x = rcos(theta)
y = rsin(theta)
------------------
Your problem:
x = 6sqrt(2)cos(-45) = 6sqrt(2)[1/sqrt(2)] = 6
y = 6sqrt(2)sin(-45) = 6sqrt(2)[-1/sqrt(2)] = = -6
