MAT 296 Hour Test 2 (MWF sections) November 5, 2009 Do all the following problems. To receive full credit for an answer or to have it considered for partial credit, you must show your work . This test has 9 problems on 9 pages. Make sure your test is complete! 1. (11 points) Find the partial fraction decomposition of f ( x ) = 5 x 2 + 4 x 4 + 4 x 2 . 2. (10 Points) Find the following indefinite integral Z x + 1 x 2 - 4 x + 5 dx . 3. (24 points) Do the following integrals converge? Why or why not? (a) Z 0 xe - x 2 dx . (b) Z π/ 2 0 sec xdx . 4. (10 points) A curve C has equation y = x 2 8 - ln x Set up an integral for finding the length of C between x = 1 and x = 2. You must simplify the integrand as much as possible, but You do not need to evaluate the integral. You only need to set it up. 5. (10 points) The curve y = x + 2 for 0 x 4 is rotated around the x -axis. Set up an integral for finding the area of the surface it generates. You must simplify
