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