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

**this other site**offers 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. (This forum currently receives LaTeX rendering from katex.org.)

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, instead, then use tags \͏( and \͏)

**or**\(\displaystyle \text{[ima}\text{th]}\) and \(\displaystyle \text{[/ima}\text{th]}\)

**or**$$ and $$.

When composing your post, you may type opening and closing tags of your choice, or you may click the

**f(x)**toolbar icon to open a dialog box in which you may select options and type your code. The dialog box provides a LaTeX preview, for checking entries.

If you would like to view specific LaTeX coding posted in this forum, then click the post's reply button.

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