Hey I am doing test corrections and need help,
Which of the following inverse functions are defined for x=-1/2 ? Select all that apply.
since |sec(x)| and |csc(x)| are both greater than 1, there is no angle x such that
sec(x) = -1/2 or csc(x) = -1/2
The rest are either always between -1 and 1 or have infinite range.
