In this video, we provide essential "math help" by explaining how to "graph" functions, beginning with a basic cosine wave ...

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 ...

The zeta function of a graph, inspired by analogues in number theory and differential geometry, encodes fundamental cycle and path data in a compact analytic form. Its prototypical instance, the Ihara ...

What is a function actually doing?”Have you ever heard that question from your child?They know the quadratic function formula ...
