For what value of $x$ does $\sin x=\sin ^{-1} x ?$ Use a graphing calculator to approximate the answer. Those two angles aren’t in the domain of the cotangent function, so they aren’t in the range of the inverse. Each domain includes the origin and some positive values, and most importantly, each results in a one-to-one function that is invertible. â1 â1 cos 2 ( Each has a base of 12 feet and height of 4 feet.
