A Concise Introduction to Numerical Analysis, 2018
If f(x) is continuous, we are guaranteed that exists, but sometimes we cannot evaluate the integral. For these cases, we use numerical methods to approximate the definite integral (area under the curve.)

An accuracy analysis of Galerkin meshfree methods accounting for numerical integration
, 2021Presently, it has been widely recognized that numerical integration plays a crucial role on the solution accuracy of Galerkin meshfree methods due to the rational nature of meshfree shape functions and the misalignment of shape function supports with ...
