Calculus 2 Lecture Notes, Section 6.3

Case 2: Integrals involving. Check to see if you can use substitution or integration by parts. If not, make the substitution x = atan((), and dx = asec2(()d(. Simplify the radical using algebra and the Pythagorean identity: Integrate. To back-substitute, use the following trick from trigonometry. ................
