Inverse Functions and Inverse Trig Functions
In the previous chapter, we looked at exponentials and logarithms. We got a lot of mileage out of the fact that ex and ln(x) are inverses of each other. In this chapter, we’ll look at some more general properties of inverse functions, then examine inverse trig functions (and their hyperbolic cousins) in greater detail. Here’s the game plan:
• using the derivative to show that a function has an inverse;
• finding the derivative of inverse functions;
• inverse trig functions, one by one; and
• inverse hyperbolic functions.
