Question

What is Double line Integral .

Answer 1

Step-by-step explanation:

A line integral is an integral where the function to be integrated is evaluated along a curve and a surface integral is a generalization of multiple integrals to integration over surfaces. It can be thought of as the double integral analog of the line integral. ... We will begin with real-valued functions of two variables

Answer 2

Answer:

A line integral is an integral where the function to be integrated is evaluated along a curve and a surface integral is a generalization of multiple integrals to integration over surfaces. It can be thought of as the double integral analog of the line integral. ... We will begin with real-valued functions of two variables.

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 R
