In this video series I show you how to graph linear inequalities. When graphing linear inequalities we now have to account for two variables. We graph linear inequalities using the same process as ...

In 2004, two mathematicians hypothesized a powerful kind of sandwich. They were studying graphs, which are collections of points (called vertices) and lines (called edges). Graphs might represent ...

The first handheld graphing calculator, the Casio fx-7000G, appeared in 1985. Since then, graphing calculators have become a common – and controversial – tool for learning mathematics. These devices ...

👉 Learn how to graph linear equations from the table of points. When given the table of points of a linear equation, we plot the x and y coordinates of the given table on the cartesian plane and join ...

There is no avoiding the constant chatter about AI these days. Really, it’s been months. As a math teacher, this struggle over new technology feels oddly familiar. More than 30 years ago, the National ...

In 1950 Edward Nelson, then a student at the University of Chicago, asked the kind of deceptively simple question that can give mathematicians fits for decades. Imagine, he said, a graph — a ...

Jacob Holm was flipping through proofs from an October 2019 research paper he and colleague Eva Rotenberg—an associate professor in the department of applied mathematics and computer science at the ...
