INVERSE TRIGONOMETRIC FUNCTIONS For the following exercises, find the exact value without the aid of a calculator. 28. sin (1) 29. cos V 3 2 30. tan '(-1) 31. cos '() 32. sin -V3 2 33. sin '(cos( ) 34. cos ( tan ( 32: ) ) 35. sin sec '( )) 36. cot sin '()) 37. tan ( cos ( 13 ) ) 38. sin ( cos x 39. Graph f(x) = cos x and f(x) - sec x on the interval [0, 27) and explain any observations. 40. Graph f(x) = sin x and f(x) = csc x and explain any observations. 41. Graph the function f(x) = 3! 5! _, on the interval [-1, 1] and compare the graph to the g f(x) = sin x on the same interval. Describe any observations
