Multiple integrals use a variant of the standard iterator notation. The first variable given corresponds to the outermost integral and is done last. ». Integrate can evaluate integrals of rational functions.
Integral - Wikipedia
https://en.wikipedia.org/wiki/IntegralIn general, the integral of a real-valued function f(x) with respect to a real variable x on an interval [a, b] is written as The integral sign ∫ represents integration. The symbol dx, called the differentialof the variable x, indicates that the variable of integration is x. The function f(x) is called the integrand, the points a and b are called the limits (or bounds) of integration, and the integral is said to be over the interv…
