For problems 4-8, find the exact values of the following definite integrals using antiderivative rules and the Fundamental Theorem of Calculus. Leave answers in radical form, in terms of In(), or in terms of e, etc. (Note: u-substitution is not necessary for any of these problems) 4. So (x2 + Vx) dx 4 TT 5. 3 sin(x) dx 3 6. S" ( tex) dx 7. S 4 x2 + Vx+ 2 .dx x 3/ 2 8. S. (x - 27) dx For problems 9-11, use your knowledge of u-substitution to evaluate the following indefinite integrals. Show your work. 9. S sin3(x) cos(x) dx 10.
