Document Summary
Closed book - calculators and one index card are allowed! Clearly write your answer (only) in the space provided after each question. Very limited partial credit or none at all for this part of the test! Determine whether the improper integral z e its numerical value if it converges! Sketch the region enclosed by the curves y = |2x| and y = x2 3, and then nd its area. Find the volume of the solid obtained by rotating about the x-axis the region bounded by the curve y = 2 2x2 and the line y = 0. A variable force f (x) = 2x 2 n moves an object along a straight line when it is x meters from the origin. Calculate the work done in moving the object from x = 1 m to x = 10 m. You must show your work on this part of the test to get full credit.
