What integral technique do I use? (13 examples, calculus 2)

Which integration technique do we use? How to choose between U-substitution, integration by parts, trig substitution, or integration by partial fractions? Here I will demonstrate 13 integrals and how we decide what technique to use on them. Here is the file for you to try all the problems first 👉   / 103126364  
Best of luck with your calculus class!
