Li-An Yeh mth 133 ss16 64540 Assignment Hw12 7.1 Integration by parts due 02/11/2016 at 11:00pm EST 1. (1 point) To evaluate Z 5 x cos4 xdx using integration by parts, we first express the integral in the form R udv . For this integral, the best choices of u and dv are as follows: u = Z xe - 8 x dx = + C (Do not include an arbitary constant ” + C ” in your answer.)
3. (1 point) [Click to see a worked example.]
2. (1 point) To evaluate Z xe - 8 x dx using integration by parts, we first express the integral in the form R udv . For this integral, the best choices of u and dv are as follows: u = Note: Pick either u = x or u = e - 8 x . dv = Then, for the correct choices of u and dv above, du = v = so that
