Solving Gaussian Integral in Seconds

How to solve Gaussian integral. The Gaussian integral, also known as the Euler–Poisson integral, is a definite integral. This integral arises in many areas of mathematics, physics, and engineering, and has a number of important properties. It is closely related to the normal distribution in probability theory and can be used to evaluate a wide variety of integrals through the use of integration by substitution. The Gaussian integral can be evaluated analytically for many values of a, b, and c, and in other cases it can be approximated numerically using techniques such as Monte Carlo integration.
