Start using laTEX

TL;DR Summary: Looking for downloadable package of symbols

Hi; I am picking up on the suggestion of using LAtex.
I know the symbols are mostly in Word scattered about the place.
Is there a downloadable package do you know that I could access please.
Thanks
Martyn

Just click on the link "LaTeX Guide" lower left above "Attach Files" to get started.

In LaTeX you type commands, not paste in symbols. For instance, to get "gamma is not equal to capital delta" you type \gamma \neq \Delta. Put that between double hashmarks and you get ##\gamma\neq\Delta##. You don't need to download any symbols - just keep a google page open so you can look up the command when you forget one! As kuruman has noted, there's a "how to use LaTeX on PF" linked below the reply box.

Or are you trying to write documents in LaTeX for personal notes, like you might in Word? You can get LaTeX compilers that do that. If that's what you want to do, are you on Windows or what?

There is a helpful "LaTeX Guide" link below the Edit window to get you started. Note that you put double-$ delimiters at the start and end of each stand-alone line of LaTeX, and double-# delimiters at the start and end of in-line LaTeX that does not need to be on its own line.

Example of in-line LaTeX: ##v(t) = L \frac{di(t)}{dt}##

Example of stand-alone LaTeX:
$$v(t) = L \frac{di(t)}{dt}$$
Also, if you right-click on a LaTeX equation in a post, you get a pop-up menu to let you view the LaTeX source or view it in other formats.

LaTeX isn't supported in thread titles, so you can use simple text math in titles if you want.

Note also that PF uses a feature called "lazy LaTeX rendering" that speeds up page loads. When you first post your LaTeX in a thread, you will not see it rendered that first time. Just refresh your browser page to force it to be rendered, and then it should render whenever you come back to that page/thread in the future.

If you have trouble using the Preview feature to check your LaTeX, you can use a website such as https://www.quicklatex.com/ or https://latexeditor.lagrida.com/ to preview your LaTeX before you post it.
