**purplemath site**explains how to format math expressions using plain text, and

**this other site**offers many math symbols for copy-and-paste.)

Also, be forewarned that there are different implementations of LaTeX on the Internet; not everything you may see elsewhere works the same way here (if at all).

At this site, each line (

**or set of lines**) of LaTeX coding must be enclosed within \(\displaystyle \text{[te}\text{x]}\) and \(\displaystyle \text{[/te}\text{x]}\) tags OR \(\displaystyle \text{[ma}\text{th]}\) and \(\displaystyle \text{[/ma}\text{th]}\) tags

While composing your post, you can insert a pair of tags by clicking the 'Add LaTeX…' toolbar icon (it looks like a calculator, to the right of a flag icon).

If you'd like to view the specific coding for any LaTeX expressions in this forum, right-click the expression and use the pop-up menu to: Show Math As > TeX Commands.

Here's an example of LaTeX:

\(\displaystyle \displaystyle cos\bigg( \frac{\pi}{3} \bigg) \cdot \int_{a}^{b} \frac{3x^{3} + 7x - 10}{\sqrt[3]{x + 4}} \; \text{dx}\)

**List of LaTeX mathematical symbols (wiki)**

\(\displaystyle \left[

\begin{matrix}

1 & 0\\

0 & 1

\end{matrix}

\right]\)

\(\displaystyle \begin{align}

1 + 2 &= 3\\

1 &= 3 - 2\\

5 - (1 + 2) &= 5 - 3

\end{align}\)

\(\displaystyle \displaystyle \lim_{x\to\infty} f(x)\)
