When asked to solve a quadratic equation, we are really finding the roots – where the parabola cuts the x-axis, therefore when we have the graph drawn, it is very easy to do this. Looking at the graph ...

An equation is a mathematical statement showing that two expressions are equal. The two expressions are linked with an equals symbol (=). The unknown variable (often the letter \(x\)) can take any ...

This example solves the weak form of the standard Laplace equation, using the Galerkin Finite Element method. is a spatially varying scalar field (e.g. potential). and are 'nabla' (divergence operator ...

The Diffusion Convection Equation is a Partial Differential Equation writen in the form: $$\frac{\partial u}{\partial t} = \nabla ( D \nabla u) + \nabla \cdot (\mathbf{c} u)$$ This Equation can model ...

A structural equation is a mathematical model that represents relationships among variables, allowing for the analysis of complex causal relationships in various fields such as economics, psychology, ...
