Problem 73E
Integrating Inverses of Functions
Integration by parts leads to a rule for integrating inverses that usually gives good results:
The idea is to take the most complicated part of the integral, in this f-1(x) case and simplify it first. For the integral of ln x, we get
For the integral of cos-1 x we get
Use the formula
to evaluate the integrals. Express your answers in terms of x.
