(a) To define the inverse sine function, we restrict the domain of sine to the interval _________. On the interval the sine function is one-to-one, and its inverse function is defined by __________ = __________. For example, __________ because _________ = _________.
(b) To define the inverse cosine function we restrict the domain of cosine to the interval __________. On this interval cosine function is one-to-one and its inverse function is defined by __________ = ________. For example, __________ because _________ = _________
