Sir, Many thanks for this systematic and detailed video. I have taught 1D Gauss Quadrature for many years. Now I need to do a 2D integral for my research, and I was not familiar with the 2D formula. Very helpful!

no disrespect. but this is not the right way to do it... if the limits of the integration are changed this method will NEVER work

Sir how to do it for three point with double integration..

Using 2 point rule evaluate the integral over the given area of the quadrilateral coordinates
(1, 0) , (1,5),(5,5) and (4,1) by Guassian quadrantine?
Can anyone give the solution please
