**Steve**, Monday, October 10, 2011 at 5:40pmThe nice thing is that the equations for sin and cosine automatically take into the signs involved.

consider the point (-1,-10) in the third quadrant. h = sqrt(101) and is always positive

sin = y/h = -10/sqrt(101) = -0.995

cos = x/h = -1/sqrt(101) = -0.0995
