What is the application of numerical integration?

Numerical integration uses the same information to compute numerical approximations to the integral of the function. An important use of both types of methods is estimation of derivatives and integrals for functions that are only known at isolated points, as is the case with for example measurement data.

What are the applications of numerical integration in real life?

It is used in physics. In physics we first consider elementary partial then integrate to find the effect due to whole body. It is used to find area of irregular shapes. Many derivations in physics use integration.

What is numerical integration with example?

Numerical integration is the method to calculate the approximate value of the integral by using numerical techniques. There are various useful and interesting methods for numerical integration such as trapezoidal rule, Simpson's rules, Gauss's, Newton-Leibnitz rules etc.
