Figure Ex-48 49-50 The function cot-x is defined to be the inverse of the restricted cotangent function cotx, 0

A Figure Ex-4b 49-50 The function cot-I x iQlefined to be the inverse of the restricted cotangent function cot x, 0 < x < IT and the function csc- x is defined to be theinverse of the restricted cosecant function IT/2 < x < n/ 2, x cscx, Use these definitions in these and in all subsequent exercises that involve these functions.
