Some Gaussian Integrals
Requires a Wolfram Notebook System
Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.
The well-known Gaussian integral can be evaluated in closed form, even though there is no elementary function equal to the indefinite integral . More generally, integrals of the form can be evaluated for positive integers . In this Demonstration, we perform numerical integrations for , with and . The results are then represented as areas under a curve (shown in red).
