MIDTERM 2 — MATH 141 — SPRING 2003 — BOYLE Use exactly ONE answer sheet per question (use the back of the sheet if needed). Put your name, your TA’s name and the question number on EACH page. Put a BOX around the Fnal answer to a question. No books, no notes, no calculators. Before handing in your test: on your Frst answer sheet, please copy the pledge, and sign. ———————————————————————————————————– 1 (a) (20 points) Compute the integral R tan 7 x sec 4 x dx . (b) (10 points) Let S n denote the Simpson’s Rule estimate for a given R b a f ( x ) dx and let E n = | S n - R b a f ( x ) dx | . Then we have a bound E n B n , where B n = ( b - a ) 5 180 (max | f ( iv ) | ) 1 n 4 where the maximum is taken over the interval [
