MATH 1271 Study Guide - Midterm Guide: Sign Your Name, Logarithmic Derivative, Multiple Choice
Document Summary
Closed book, closed notes, no calculators/pdas; no reference materials of any kind. Turn o all handheld devices, including cell phones. Show work; a correct answer, by itself, may be insu cient for credit. Arithmetic need not be simpli ed, unless the problem requests it. I understand the above, and i understand that cheating has severe consequences, from a failing grade to expulsion. Sign your name: (5 pts) (no partial credit) find the logarithmic derivative of (2 + sin(2x))cos x w. r. t. x. Circle one of the following answers: multiple choice (cid:18) 2 cos(2x) (cid:19) 2 + sin(2x: (5 pts) (no partial credit) find the derivative of (2 + sin(2x))cos x w. r. t. x. circle one of the following answers: (cid:18) 2 cos(2x) (cid:19)(cid:21) 2 + sin(2x) ( sin x) (cos x)(ln(2 + sin(2x))) + ( sin x) (a) [(2 + sin(2x))cos x] (b) [(2 + sin(2x))cos x] (cid:18) 2 cos(2x) (cid:18) 2 cos(2x) At most one of the following statements is true.
