Precalculus64ASSIGNMENT 15: INVERSETRIGONOMETRIC FUNCTIONSRead the following information. Then study pages 550–562 inyour textbook, Precalculus.Complete the “Check Points” as youcome to them in the textbook. The answers are in the back ofyour textbook.IntroductionHere are some reminders that will be of use to you as youbegin this section on inverse trigonometric functions.■If the name of a function is f, then its inverse is f –1. Note: The superscript is notan exponent in this context.■If a point (a, b) is on the graph of a function, then thepoint (b, a) is on the graph of its inverse. The two graphswill be reflections of each other about the diagonal line y = x.■Only one-to-one functions have inverse functions. Inother words, if a horizontal line intersects the graph of a function in more than one point, that function won’t have an inverse.Self-Check 14To reinforce what you’ve just studied, complete exercises 1, 5, 9, 13, 17, 21, 23, 25, 27, 29,33, 37, 39, 41, and 43 on pages 546–547 of your textbook.
