However, in multivariable calculus we want to integrate over regions other than boxes, and ensuring that we can do so takes a little work. After this is done, the chapter proceeds to two main tools for …

In addition, the chapter on differential equations (in the multivariable version) and the section on numerical integration are largely derived from the corresponding portions of Keisler’s book.

In single variable, you could do this by proving that the limit from the left and the limit from the right aren't equal. In multivariable, you just need to prove that the limit isn't the same for any two directions.
