We use a system named LaTeX to generate math symbols and format expressions in the forum. Using LaTeX requires learning some programming codes and syntax. You can google for tutorials and examples. Some references and examples appear below. (As an alternative to LaTeX, the 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.

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:

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

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

$\frac{A}{B} = C^{2} \quad \quad \sqrt{x^2} = |x|$

\lim_{x\to\infty} f(x)​

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

\sqrt{y} = x^2 + bx + \bigg( \frac{b}{2} \bigg)^2​

$\sqrt{y} = x^2 + bx + \bigg( \frac{b}{2} \bigg)^2$
