PART 1 : INTEGRATE , SHOW ALL WORK to receive credit. [1]-[3] Integrate with only one u-substitution for each problem. (Avoid changing variables multiple times.) Clearly define that u-substitution and identify the formula from the table that you are using. [1] edx 9 - 10ex -e2x [2] dx x Inx V3 Inx - 7 [3] x dx x* + 2x2- 2 [4] Use the method of Partial Fractions. 5x4 + x3 - 4 dx x'(x2 + 2)
