A single integral calculates the area under a curve in one-dimensional space, while a double integral calculates the volume under a surface in two-dimensional space. Single integrals have one variable of integration, whereas double integrals have two variables of integration. ...
Evaluating Double Integrals over Given Regions: Integrating over a region would involve a double integral, the bounds of which need to be established so that the whole region is represented. This requires inspection of the graph ...
1. Evaluate each of the following double integrals a) \iint_{R} x^{3} dA, where R is the region bounded by y = x + 1, and y = x^{2} - 1. b) \iint_{R} (x^{2} + y^{2})^{3/2}dA, where R...
Double Integrals: In order to solve this problem, we will need to set up and evaluate a double integral. Note that we are given only bounds on one of the variables, we will need to use those bounds in order to find the bounds for the other variable. Note that...
Recently, Crespo–Blanco–Gasiński–Harjulehto–Winkert [16] studied the so-called double phase operator with variable exponents given by (1.1) withsuch thatfor all,andis the corresponding Musielak–Orlicz Sobolev space being a uniformly convex space. Under the assumptions above, it is shown tha...
The expression f(x)f(x) is called the integrand and the variable xx is the variable of integration.Power Rule for Integrals For n≠−1n≠−1, ∫xndx=xn+1n+1+C∫xndx=xn+1n+1+CEvaluating indefinite integrals for some other functions is also a straightforward calculation. The f...
In this section, we analyze the quadrature error when applying a double exponential formula for discretizing certain integrals. For \theta \ge 1, \delta >0 we define the sets \begin{aligned} D_{d(\theta )}:=\Big \{z \in \mathbb {C}: \left| {\text {Im}}(z)\right|< d(\theta...
Moreover, it is easy to obtain that the bound (α2+α−2k)(k−2−α)2(α2+3α+2) is monotone decreasing with respect to the variable k(k > 3) for 1 < α < 2. Thus, we have (α2+α−2k)(k−2−α)2(α2+3α+2)≥(α2+α−8)(2−α)2(α2+3α+2)...

The volume of the region seen between the function's surfaces is represented by the double integral of a positive two-variable function in calculus. Double integrals are used to calculate the area of a region, the volume beneath a surfa...
