In my recent publication on the H-function of two variables [4], the double integrals are evaluated by using the technique of known integrals. In the present study a very general type of double ...

Functions of Two Variables Functions of two variables can be visualized in many ways: heat maps in 2D, contour curves in 2D, wireframes in 3D, surfaces in 3D. We begin by defining a function of two ...
