![]() Significant Figures: Choose the number of significant figures or leave on auto to let the calculator determine number precision. Answers will be the same whether in feet, ft 2, ft 3, or meters, m 2, m 3, or any other unit measure. Units: Units are shown for convenience but do not affect calculations. Height is calculated from known volume or lateral surface area. Surface area calculations include top, bottom, lateral sides and total surface area. This calculator finds the volume, surface area and height of a triangular prism. ![]() It's a three-sided prism where the base and top are equal triangles and the remaining 3 sides are rectangles.

In Example 5.12, we could have looked at the region in another way, such as D =. = ∫ x = 0 x = 2 d x Integrate with respect to x using u -substitution with u = 1 2 x 2. ![]() = ∫ x = 0 x = 2 | y = 1 / 2 x y = 1 d x Integrate with respect to y using u -substitution with u = x y where x is held constant. = | x = 0 x = 2 = 2 ∫ x = 0 x = 2 ∫ y = 1 2 x y = 1 x 2 e x y d y d x = ∫ x = 0 x = 2 d x Iterated integral for a Type I region. ∫ x = 0 x = 2 ∫ y = 1 2 x y = 1 x 2 e x y d y d x = ∫ x = 0 x = 2 d x Iterated integral for a Type I region. Since D D is bounded on the plane, there must exist a rectangular region R R on the same plane that encloses the region D, D, that is, a rectangular region R R exists such that D D is a subset of R ( D ⊆ R ). ![]() General Regions of IntegrationĪn example of a general bounded region D D on a plane is shown in Figure 5.12. Most of the previous results hold in this situation as well, but some techniques need to be extended to cover this more general case. In this section we consider double integrals of functions defined over a general bounded region D D on the plane. We also discussed several applications, such as finding the volume bounded above by a function over a rectangular region, finding area by integration, and calculating the average value of a function of two variables. We learned techniques and properties to integrate functions of two variables over rectangular regions. In Double Integrals over Rectangular Regions, we studied the concept of double integrals and examined the tools needed to compute them. 5.2.5 Solve problems involving double improper integrals.5.2.4 Use double integrals to calculate the volume of a region between two surfaces or the area of a plane region.5.2.3 Simplify the calculation of an iterated integral by changing the order of integration.5.2.2 Evaluate a double integral by computing an iterated integral over a region bounded by two vertical lines and two functions of x, x, or two horizontal lines and two functions of y.5.2.1 Recognize when a function of two variables is integrable over a general region.
