Answers without supporting work will receive no credit, except for multiple choice problems. Circle your answers: (20 points) circle your answer, or ll in the blank. (a) the range of the function f (x) = sin 1(x) is, [ 1, 1, [0, ] 2: not listed (b) the statement, cos(cos 1(x)) = x for all real numbers x is, true, false (c) the exact value of cos 1(cos( 2. (a) (6 points) rewrite the expression cos(tan 1(x)) as an algebraic expression. (b) (6 points) write the expression 3 csc(x) tan(x) + sec(x) in terms of cos(x) only. (c) (8 points) find the exact value of cos( x. , and 270 < x < 360 : (20 points) circle your answer. (a) simplify tan(x + 4: tan(x) + 1 ii) tan(x) + 1.
