MA 125 Midterm: 1-11s-test3
Document Summary
Clearly write your answer (only) in the space provided after each question. You do not need not to show your work for this part of the test. No partial credit is awarded for this part of the test! Di erentiate the function y = x ln(x) x. Find the derivative of the following quotient f (x) = ex x. Suppose h(x) = of h (1). ln(x) g(x) where g(1) = 5 and g(x) is di erentiable. Find the derivative of the function y = arctan (x2). You must show your work on this part of the test to get full credit. Displaying only the nal answer (even if correct) without the relevant steps will not get full credit. The radius of a circular plate is given as 10 inches with a maximum error in measurement of. Problem 3 (1) di erentiate the function, and simplify completely by expressing your answer as a single fraction. g(x) = ln(cid:18) ex + 1.
