Copy and complete the following passage with the most appropriate words, symbols or equations. When graphing ?? = 3 sec 0.5??, the period is _______________. An appropriate interval is ____________, and the asymptotes occur in this interval where _________________. Thus, the asymptotes in this interval are ?? = ?? and _____________. We can define an inverse sine function on a restricted domain. The inverse sine function is the function ??????-1 with the domain ____________and range _______________ defined by ??????-1 ?? = ?? if and only if _________________. The inverse sine function is also called ______________ denoted by ______________. Thus ?? = ??????-1 ?? is the number in the interval ________________ whose sin is _________________. In fact from the general properties of inverse function, we have the following cancellation….
