Differentiating this function still means the same thing--still we are looking for functions that give us the slope, but now we have more than one variable, and more than one slope. Visualize this by ...

Functions of two variables appear frequently in engineering studies. Students have particular difficulties in understanding how the graphs of these functions are. This paper presents a sequential mode ...

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 ...

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 ...

this paper is devoted to the consideration of optimization problem for function of two variables, which, in the general case, is poly-extremal and undifferentiated. One of the most commonly used ...

ABSTRACT: The aim of the present paper is to establish some new integral inequalities of Gronwall type involving functions of two independent variables which provide explicit bounds on unknown ...
