Topics
-
Volumes and Average Value. (6.2) Be able to use formula (1) to find the volume of a solid by determining the cross-sectional area function and integrating it. Also know formula (6) for the average value of a function.
-
Volumes of Revolution. (6.3 and 6.4) Know how to use disks, washers, and cylindrical shells to find the volume of a solid of revolution.
-
Integration by Parts. (7.1) Know how to use integration by parts to evaluate a given integral. Remember LIPET for the choice of u.
-
Trigonometric Integrals. (7.2) You should be able to integrate any function of the form sinm
(x)cosn(x) or secm(x)tsnn(x), using either substitution if possible, or the two basic trigonometric identities and reduction formulas. I will provide the reduction formulas 44, 45, 46 and 48 in the back of the book, but you should know the integrals of sec(x) and tan(x).
-
Trigonometric Substitution. (7.3) Know how to use a trigonometric substitution to evaluate integrals involving a2-x2, x2-a2, and a2+x2.
-
Partial Fractions. (7.4) Know how to use the partial fractions method to evaluate rational functions where the denominator has some number of linear factors (possibly repeated), as well as irreducible quadratic factors (but not repeated).
-
Completing the Square. Some of the trigonometric substitution and partial fractions problems may require you to complete the square. See pages 16 and 17 in the text.
