The statistical physics of graphs and partition functions represents a vibrant intersection of graph theory, statistical mechanics and computational complexity. By summing over an ensemble of ...

Learn and revise how to solve quadratic equations by factorising, completing the square and using the quadratic formula with Bitesize GCSE Maths Edexcel.

The graph of a function f is the set of all points (inputs, outputs) = (x,y) in the plane which satisfy the equation y=f (x). You can move the input below and see how the graph give a visual ...

Basics: Making graphs with kinematics stuff part II So, you still want to make a graph with that kinematics data? You think that graphs on paper are too barbaric?

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 ...

How to Graph a Function in Excel. 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 ...

For novices, functions are one of the most intimidating features of OpenOffice.org's Calc. Newcomers quickly learn that functions are a main feature of spreadsheets, but there are almost four hundred, ...

Graphs of quadratic functions All quadratic functions have the same type of curved graphs with a line of symmetry.
