Question

explain the double integral​

Answer 1

The multiple integral is a definite integral of a function of more than one real variable, for example, f or f. Integrals of a function of two variables over a region in R² are called double integrals, and integrals of a function of three variables over a region of R³ are called triple integrals.

Answer 2

Definition of Double Integral. ... If the definite integral b∫af(x)dx of a function of one variable f(x)≥0 is the area under the curve f(x) from x=a to x=b, then the double integral is equal to the volume under the surface z=f(x,y) and above the xy-plane in the region of integration
