The first pdf file can be used as a lesson in introduction to inverse trigonometry.

It covers three inverse trig functions:

- arcsine

- arccosine

- arctangent

Also included are:

- domain and range of each inverse trigonometric function

- graphs of the three inverse trigonometry functions

- examples of finding the inverse trig values

The second pdf file is a worksheet to provide students with 24 inverse trigonometry drill problems (arcsin, arccos, arctan) + the answer sheet (given in both radians and degrees).

It can be used as a class exercise, homework, or as a quiz.

All typed in LaTeX for a beautiful and professional look.
