Trig Subs | How To Choose The Substitution & Deal With Indefinite Integrals

Instead of guessing or memorizing what trigonometric substitution to use, I'll walk through how I anticipate what is the best trig sub to use. In this example it will be an indefinite integral, and that poses its own set of problems. We have to be careful about our restriction on the domain as before, but now we have to back solve the final answer to put it in terms of the original variables. This involves a bit of trigonometry.
