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 ...

One of my favorite demos at Disrupt NYC was from an education startup called Desmos that is reinventing the whiteboard to make it browser-based and interactive (watch their Disrupt video below). One ...

Concepts covered in this course include: standard functions and their graphs, limits, continuity, tangents, derivatives, the definite integral, and the fundamental theorem of calculus. Formulas for ...

In this video, we provide essential "math help" by explaining how to "graph" piecewise functions. This "math tutorial" breaks down what is a function into its component parts, explaining the ...

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 ...
