"Science is what we understand well enough to explain to a computer. Art is everything else we do." -- Donald Knuth

### First, a review of an important trig property you’ll be using here:

Pythagorean Identity

### Goal: Get into one of these forms

Which one? Depends on whether secant is even or odd!

or

### If power of secant is even

Save out a . Convert the remaining secants using:

### If power of secant is odd

Save out a . Convert the remaining tangents using:

### Only has tangent

Replace a with

May require multiple applications of this property

### Only has secantNo tangent

If even: Same as earlier…Save out a . Convert the remaining secants using:

### Only has secantNo tangent

If odd: use integration by parts.
