5. Integrate:
Choose u (to differentiate (“du”)) dv (to integrate (“v”))

6. Integrate:
You can also use u-substitution!

8. Trig Functions: (also on Day 10)
Recall that when a trig integral has ODD powers, we save one term for the “du” and replace the remaining even powers with:
And when a trig integral has EVEN powers, we use the following trig identities to integrate.
