In order to use inverse trigonometric functions, we need to understand that an inverse trigonometric function “undoes” what the original trigonometric function “does,” as is the case with any other function and its inverse. That means that any horizontal line passes through only one point on the graph of the function. 1 The Arcsine Function My sine is x; who am I? So, in order to ﬁnd the inverse functions for sine, cosine, and tangent, we must restrict their domains to intervals where they are one-to-one. 0000003867 00000 n There are two popular notations used for inverse trigonometric functions: Adding “arc” as a prefix.
