I just need basics work on how to solve this problems. (my frs have already solved most of the, if you could check and verify that would be grate) I don't need explanation

Evaluate or give an expression for the answer. 16 ) tan - 1 ( - V3 ) = 17) cos -1/ sin 4 7) 18) cot-1 (-1 ) = 20 / W7 19 ) sec sin 1 - 12 20) tan -1 ( tan In) = 21 ) csc cos - 1 ( - 6 ) 6 4 81 a7- 6 = 100 9 = 8 = 105 22 ) cot (csc-1 ( - 5 ) ) = 23) sec (arcsin (12) )= &0 sin " ( 6 ) 24 ) Graph and label f (x) = sin- C (x - 3) ) - n. a - o d . 6 - 1/2 C - 3 + TT
