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 ...

In this article, I describe generalization activity as an opportunity to learn about seventh graders' understanding of functions. A group of students who had studied functions modeled a multivariable ...

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 ...

The theory of functions of a complex variable plays an increasingly important part in the applications of mathematics to physical problems.

THE theory of functions of a real variable is a subject of fairly recent date and is necessarily expanding as new theorems are discovered and fresh generalisations effected. On the other hand, the ...
