Integral as area between two curves.Double integral as volume under a surface z = 10 − (x2 − y2/8). The rectangular region at the bottom of the body is the domain of integration, while the surface is the graph of the two-variable function to be integrated.
In mathematics (specifically multivariable calculus), a multiple integral is a definite integral of a function of several real variables, for instance, f(x, y) or f(x, y, z). Physical (natural philosophy) interpretation: S any surface, V any volume, etc.. Incl. variable to time, position, etc.
Integrals of a function of two variables over a region in (the real-number plane) are called double integrals, and integrals of a function of three variables over a region in (real-number 3D space) are called triple integrals.[1] For multiple integrals of a single-variable function, see the Cauchy formula for repeated integration.
