Math 221: Chapter 14 Exam Study Guide

In-Class Exam

  1. A plane region is described. Write the limits for the double integral for both orders of integration.
  2. Write a double or triple integral that can be used to find the area or volume. Use the coordinate system indicated. Four parts: an area in polar coordinates and a volume in rectangular, cylindrical, and spherical coordinates. You will need to know the Jacobian for each coordinate system. Do not evaluate the integrals, only set them up.
  3. A surface is given.
    1. Write a double integral in both rectangular and polar coordinates to find the area of the region under the surface. Then evalute whichever one is easier.
    2. Write a double integral to both rectangular and polar coordinates to find the area of the surface. Then evalute whichever one is easier.
    3. Write a double and triple integral to find the volume of solid bounded above by the surface. Switch to either polar or cylindrical coordinates before finding the volume.
  4. Transform the region R into a rectangular region S. Write the transformations and label the curves with their new equations. Find the Jacobian. Use the transformation to evaluate the integral.
  5. Find the mass and center of gravity for the laminate bounded by the given equations having the indicated density.
