5. [-/6.66 Points] DETAILS Verify the identity algebraically. Use the table feature of a graphing utility to check your result numerically. (Simplify at each step.) 8 8 = -16 csc(x) cot(x) cos(X) + 1 cos(X) - 1 8 8 - 8 + 8 cos(x) + 8 + cos(X) + 1 cos(x) - 1 (cos(x) + 1)(cos(x) - 1) = cos (x) - 1 -sin (x) = -16 . cos(X) sin(x) sin(x) = -16 csc(x) cot(x)11. [-/6.66 Points] DETAILS Use the figure to find the exact value of the trigonometric function. cot 8 152. [46.66 Points] DETAI LS Find the exact values of the six trigonometric functions of the angle E! for each of the two triangles 2.5 E 6 5 A I 12 Smaller triangle Larger triangle Explain why.r the function values are the same. 0 The triangles are congruent so the trigonometric function values must be the same. 0 The triangles are similar so corresponding sicles are proportional. 10.
