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

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

Also, be forewarned: There are different implementations of LaTeX on the Internet; not everything you might 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**within \(\displaystyle \text{[ma}\text{th]}\) and \(\displaystyle \text{[/ma}\text{th]}\) tags

**or**within \͏[ and \͏] tags. Each of those three tag options will default to display style. If you would like to force inline style, then use the tags \͏( and \͏) or $$ and $$, instead.

While composing your post, you can insert a pair of tags by clicking the

**f(x)**toolbar icon. Or, you can simply type the tags.

Here's an example of LaTeX:

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

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