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 ...

Microsoft Excel is designed to organize and interpret small and large amounts of data. Building a curved graph in Excel based on X and Y data points is fairly simple. You begin by adding the data ...

In this video, we provide essential "math help" by demonstrating how to "graph a function" that is defined piecewise. This ...

Graphing a piecewise function can be confusing for students. So in this video I go through the steps you will want to take to graph any piecewise function.

If you understand the definition of a mathematical function, a good way to judge it is that any line drawn parallel to the y-axis intersects with the values in the function’s curve only once. The same ...
