4.10 Inverse Trigonometric Functions



The inverse functions for the sine, cosine, and tangent are introduced. In defining them, issues are pointed out that must be considered in defining the inverse of any periodic function. Then the derivative of the inverse sine and the inverse tangent functions are derived. Their companion integration formulas give two new integrals that can be calculated from the Fundamental Theorem.

By the end of your studying, you should know:

On-screen applet instructions: The applet allows you to experiment with the sine, cosine, and tangent functions to limit their domains for the purpose of defining their inverse functions. Use the pull-down menu to select the sine, cosine, or tangent. Then drag the mouse along the curve to identify a domain over which an inverse function can be defined.
