Suppose that the terminal point determined by T is the point (-3/5,4/5) on the unit circle. Find the point determined by 2pi-t.

Question

Answer 1

I believe that T and t are the same, so you ought not to have given it two different symbols (i.e. you've been very loose with capitalization).

The answer that you seek will give you an angle in quadrant III, based on original angle (given) in quadrant II.
Its coordinates will be (-3/5, -4/5)
