Z 5. un du = 1 un+1 + C n+1 6. sin(u) du = − cos(u) + C 7. cos(u) du = sin(u) + C 8. 1 du = tan−1 (u) + C 2 u +1 √ 9. 1 du = sin−1 (u) + C 2 1−u 10. Sum/Difference Formula Z f (x) ± g(x) dx = Z f (x) dx ± Z g(x) dx Constant Multiple Rule Z k f (x) dx = k Z f (x) dx 1 Z eu du = eu + C Z bu du = Z 1 du = ln |u| + C u Z 1 bu + C (ln b) k du = k u + C Z sec2 (u) du = tan(u) + C
