please help

9. (3 points) cos( ?) = a) because the terminal point is (- V3 2' 2 b) and cosine gives the x-coordina because the terminal point is (- V3 2 and cosine gives the y-coordinat c) 2 because the terminal point is (- V3 2 ") and cosine gives the x-coordina d) because the terminal point is (- V2 V2 2 ' 2 and cosine gives the x-coordinate y-coordinate. e) V3 2 because the terminal point is 2 ' 2 and cosine gives the y-coordinate 10. (3 points) The exact value of sin 1(--) is a) because sin( and the range of inverse sine is [- 2'21 b) because sin(- = and the range of inverse sine is [- C) because sin(- = and the range of inverse sine is [0, ]. 3 117 = and the range of inverse sine is [0, 2x]. d) because sin( 6 2 6 = and the range of inverse sine is [0, ]. e) because sin(
