Ans: Riemann sum is the basic requirement for evaluating the integral.

Step by step solution

01

Step 1. Given information: 

definite integral and double integral.

02

Step 2. Discussing the similarities and differences between the definition of the definite integral and double integral:

For a definite integral, equal to the limit of Riemann sum of a function of a single variable f(x)over a closed interval (say [a, b]) as the number of subintervals goes to .

Whereas, for a double integral, equal to the limit of a double Riemann sum of a function of two variables f(x,y)over a rectangular region defined in two directions x and y (say axb,cyd)that has been subdivided into smaller subrectangles in both the x and y directions as the numbers of subintervals in those two directions goes to .
