Suppose that 0 is an angle in standard position whose terminal side intersects the unit circle at (15/17,-8/17) . Find the exact values of tan 0,csc 0 , and cos 0.

Answer 1

cosθ = 15/17 and sinθ = -8/17

So, tanθ = sinθ / cosθ = -8/15 and cscθ = 1 / sinθ = -17/8

Answer 2

15,17 and -8,17 make horizontal line; there's no angle.
