MATH 1225 Study Guide - Midterm Guide: Riemann Sum
Document Summary
Multiple choice: no partial credit will be given, clearly circle one answer, no calculator, the graph of a function f with domain [ 2, 10] is given below. Suppose we compute a right-hand riemann sum to approximate z 7. 5 f (x) dx. (a) the approximation is an overestimate. (b) the approximation is an underestimate. (c) the approximation is exact. (d) we cannot determine if the approximation is an (over/under)estimate in this case. 2 (a) z 3 (b) z cos(x + 1) dx =z 3 dx =z 1 x ln|x| u du. 0 (c) z 1 (d) z x2px3 + 3 dx = dx =z (cid:18) 1. B: determine which of the following integrals is de ned by the limit n " n lim. Xi=1(cid:18) 5 n (cid:19) cos(cid:18) + i(cid:18) 5 n (cid:19)(cid:19)# cos(x) dx (a) z 4 . 0 sin(x) dx (c) z 5 cos(x) dx (d) z 5 .
