Quadrature Rules in 1D Through 3D — Lesson 2

The development of basis functions in multiple dimensions is continued in this video. One of the important aspects of this development is numerical integration, which will be discussed here for 1Dthrough 3D. Gaussian quadrature is needed for the integration. The use of Gaussian quadrature and weighting functions in each direction is shown, and the integrals are evaluated for the bi-unit domain.
