Integrable systems and orthogonal polynomials form a vibrant research frontier that bridges pure and applied mathematics. Integrable systems are distinguished by their rich symmetry properties and the ...

Graphing calculators are important tools for students and academics. They can solve complex equations, show you the graph for additional answers, and do stuff that normal calculators can’t do. Most of ...

In this article, we will demonstrate how to use the graphing feature in the Windows calculator to try and make mathematics more fun. Microsoft has always strived to kick up a notch the Windows ...

Plotting a graph takes time. Often mathematicians just want to know the key features. These are: shape, location and some key points (such as where the graph crosses the axes or turning points). So ...

Graphing calculators are a mainstay of both high school and college-level math and science courses. Most of us have had, or will have, experience working with either a Casio or a Texas Instruments ...
