An equation of the form \(y = mx + c\) where \(m\) and \(c\) are numbers, gives a straight line when values of \(x\) and corresponding values of \(y\) are plotted on a grid. A straight line is a ...

Commutative algebra and graph theory are two vibrant areas of mathematics that have grown increasingly interrelated. At this interface, algebraic methods are applied to study combinatorial structures, ...

This paper presents a conceptual analysis for students' images of graphs and their extension to graphs of two-variable functions. We use the conceptual analysis, based on quantitative and ...

This paper provides another proof of the Attouch Theorem relating the epigraphical limit of sequences of convex functions to the set limit of the graphs of the subdifferentials.

If you or your kids are preparing for an advanced math or science course, you’re going to need a graphing calculator. These handy machines can process complex calculations (and simple ones), including ...

Whether you’re a college student enrolled in a calculus course or a professional accountant with your own firm, having a dedicated calculator is essential to your success. These purpose-built devices ...
