Mathematics 115b Final Examination 5/10/08 Name: Section: Please answer all TWELVE questions; each question is worth TEN points. You may use the table of integrals supplied with the test. However, books, notes, calculators, computers, cellphones may NOT be used. 1 2 3 4 5 6 7 8 9 10 11 12 Total (1) (a) Find F 0 ( x ) where F ( x ) = Z cos x sin x e t 1 + t 2 dt . (b) For each of Z π/ 3 0 sec 2 x dx , Z 2 π/ 3 π/ 3 sec 2 x dx , Z π 2 π/ 3 sec 2 x dx , either evaluate the integral or explain why the Fundamental Theorem of Calculus does not apply.
