Simple, Inline Equations You can do a simple inline equation by using $an equation here$. For example, you might do $\lim\limits_{n \to \infty} \frac{1}{2^n} i\bar z$ which, if we put a little fake text around it, gives Numbered, Centered Equations When writing papers or other documents, ...

Sometimes, it can be difficult to find the mathematical symbol you need. There are several options here. The first (and quickest) is to use Detexify, where you draw the symbol you'd like, and it tries to find what you want, like as shown below: Another option is to use the comprehensive LaTeX sym...

While standard LaTeX is all that is needed for most simple mathematical formulae and equations, sometimes more symbols and tools are needed. There are multiple packages available that will enhance your equations and provide you with more to work with. Three of the main packages are described below. ...

Let's say you cannot find the symbol you need anywhere. You can create a custom symbol. For example, the code \documentclass{article} \usepackage{graphicx,amsmath,amssymb} \DeclareRobustCommand{\diamondtimes}{% \mathbin{\text{\rotatebox[origin=c]{45}{$\boxplus$}}}% } \begin{document} $a\d...
