If you want to successfully navigate high school and college math classes, make sure you buy a graphing calculator. More advanced graphing calculators may come with additional features that can make ...

Anyone who’s taken classes in geometry, algebra, trigonometry or other advanced math forms has certainly encountered the graphing calculator before. These multi-function devices make incredibly ...

A mathematical function is a formula that takes an input, x, applies a set of calculations to it, and produces an output called y. By calculating a function at a large number of set intervals, it is ...

Functions of Two Variables Functions of two variables can be visualized in many ways: heat maps in 2D, contour curves in 2D, wireframes in 3D, surfaces in 3D. We begin by defining a function of two ...

Working with the graphs of trigonometric functions Trigonometric graphs Trigonometric graphs can be sketched when you know the amplitude, period, phase and maximum and minimum turning points.

We put forward the concept of measure graphs. These are (possibly uncountable) graphs equipped with an action of a groupoid and a measure invariant under this action. Examples include finite graphs, ...
