This page titled 3.1: double integrals is shared under a gnu free documentation license 1.3 license and was authored, remixed, and or curated by michael corral via source content that was edited to the style and standards of the libretexts platform. in single variable calculus, differentiation and integration are thought of as inverse operations. To illustrate computing double integrals as iterated integrals, we start with the simplest example of a double integral over a rectangle and then move on to an integral over a triangle. example 1 compute the integral \begin{align*} \iint \dlr x y^2 da \end{align*} where $\dlr$ is the rectangle defined by $0 \le x \le 2$ and $0 \le y \le 1. Solution. use a double integral to determine the volume of the region formed by the intersection of the two cylinders x2 y2 =4 x 2 y 2 = 4 and x2 z2 = 4 x 2 z 2 = 4. solution. here is a set of practice problems to accompany the double integrals over general regions section of the multiple integrals chapter of the notes for paul dawkins.

Volume = ∬ r f (x,y) da volume = ∬ r f (x, y) d a. we can use this double sum in the definition to estimate the value of a double integral if we need to. we can do this by choosing (x∗ i,y∗ j) (x i ∗, y j ∗) to be the midpoint of each rectangle. when we do this we usually denote the point as (¯¯xi,¯¯yj) (x ¯ i, y ¯ j). Section 15.3 : double integrals over general regions. in the previous section we looked at double integrals over rectangular regions. the problem with this is that most of the regions are not rectangular so we need to now look at the following double integral, ∬ d f(x, y)da. where d is any region.
