Let 𝑅 be any subring of the reals. We present a generalization of linear systems on graphs where divisors are 𝑅-valued functions on the set of vertices and graph edges are permitted to have ...

We develop parametric classes of covariance functions on linear networks and their extension to graphs with Euclidean edges, that is, graphs with edges viewed as line segments or more general sets ...

Linear equations can be shown on a graph. Find out how to create one in this Bitesize KS3 maths video. A quadratic function can be drawn as a parabola on a graph. Find out how to plot the graph in ...

It only makes sense. I did linear regression in google docs and I did it for python. But what if you neither of those? Can you do it by hand? Why yes. Suppose I take the same data from the pylab ...

I've been grading calculus exams this week, and even though my students did quite well overall there were a couple of errors that I see every semester. Errors that make mathematicians' heads explode.

Data from an experiment may result in a graph indicating exponential growth. This implies the formula of this growth is \(y = k{x^n}\), where \(k\) and \(n\) are constants. Using logarithms, we can ...
