Find the indefinite integrals and evaluate the definite integrals. In some problems a particular change of variable is suggested. 6x +15 4. (10 pts) dx, u = x2 + 5x +7 x2+5x+7 1 5. (10 pts) Jo 4+9x2 dx, u = 3x a. Use the integration table if necessary. (State which integral in the table you used.) i. http://scidiv.bellevuecollege.edu/dh/Calculus_all/CalculusRefFacts 1. Note: If you use formulas #28 and #29, there is a typo. "a2" should just be "a". #21b is missing a "+x" b.
