Document Summary

Midterm 1 math 141h fall 2003 boyle: put a box around the nal answer to a question, no books. No calculators, cell phones or other electronic devices. 2. (10 points) let f (x) = sin(1/[x2 + 1]), with the domain of f being the interval (0, ). Justify your answer: (25 points) find a formula for the function y = f (x), de ned on the interval (0, + ), which solves the following initial value problem: (x) dy dx. [hint: suppose g is another solution, and show g/f is the constant function equal to 1 for all x. : in parts (a)-(d) below, compute the limit (6 points for each part). The possible answers are a real number, + , , or dne (does not exist). (a) lim x arcsec(x) (c) lim x 0 cos(x) 1 sin(x2) ln(x3 + 5) (b) lim x ln(x)
