Document Summary
11 sheet of notes: graphing calculators are not allowed, in order to receive credit, you must show your work. Evaluate the following double integrals. (a) (8 points) Zzr x sec2(xy) da, r = [0, /4] [0, 1] (b) (8 points) 2xy da d is the triangle with vertices (0, 0), (1, 2) and (0, 3). 2 (9 points) closed rectangular region with vertices (0, 0), (0, 2), (3, 0) and (3, 2). Find the absolute maximum of the function f (x, y) = x + 2y xy on the. 3 (8 points) then the total resistance r of the circuit is given by. If three resistors with resistances r1, r2 and r3 are connected in parallel, Suppose that the resistances are measured in ohms with r1 = 25, r2 = 40 and r3 = 50, and that there is a possible error of 0. 5 ohms in each measurement.
