Triple Integrals for the Sketching-Impaired
Wm. Douglas Withers · College Mathematics Journal · 2017
SummaryThis article describes a method for setting up triple integrals without sketching a three-dimensional object. Making such a sketch presents a hurdle for many students. I have employed this method in the classroom for some years with good success, even among students previously stymied by triple integrals. Assuming an initial list of equations or inequalities describing the region, the method can be summarized in a few rules for manipulating them.
