Concise Modular Calculus [78/97]: Triple Integrals over General Regions

(4/6 on Integration of Multivariable Functions) Justifies how the integration over regions other than boxes is accomplished with iterated integrals in which the bounds of the inner integrals depend on the integration variables of the outer integrals. Suggests two methods to set up triple integrals over general regions. Explains how to interchange the order of integration in this situation. Shows how to compute the center of mass of a three-dimensional object.
