Default How do I make exponents and Greek letters?

Occosionally I like to use a formula, but there are some symbols which I do not know how to make with the editor. And I know it is possible, because I see these symbols in other posts.

Some symbols I would like to use and don't know how to make are: exponents, indices, the square root sign, Greek letters, the integral sign, the inverted delta (or nabla) sign, the Poincaré square sign and the curved d's (partial differentials).

Superscripts and subscripts are easy. Use the following codes
PHP Code:
[sup]super[/sup]script and [sub]sub[/sub]script
to produce superscript and subscript.

I can't help with the special cahracters, though.

Find the post using the symbols, use the Quote feature to get a copy of the text, then it's copy and paste.

For the Greek letters, you can use Unicode characters in the following format:

&# (number) ;

They are in sequence: in the upper case, alpha is 913 and omega 937 (the gap is between rho and sigma - 930 only shows up as an empty box in my browser); in the lower case, the numbers are 945-969 with 2 different symbols for the sigma.

Thus, π = π

A general tip: open a blank Word document (assuming you have MS Word on your computer), insert the symbol of your choice (this is standard Word stuff), copy and paste it (ctrl-C, ctrl-V) into your post.

You might also want to write your post in Word, then copy&paste it into the BAUT window (avoids problems with losing your writing efforts, due to being logged off, browser problems, etc).

An example: € é ä Ж ∫

Of course, it doesn't always work (e.g.  - the 'belongs to' symbol, as in sets)

Default Greek

Try ascii codes ß Γ π Θ.
Seems to work ⌠⌠ 'cept for that one (integration) All the greek is working!
This is my first attempt i will now go on and obsessivly check them all!

How to do.
Just get a list of ascii codes of the net or an old DOS book. When you want a greek letter look it up hold the Alt key while tapping in the number (numerical key pad only!) let go of the Alt Ω! Example capital theta "Alt+233 = Θ"

Occaisionally i have used this trick to include non keyboard characters in my passwords. This must be done with care though as some platforms wil put the wrong character in!

Also doesn't work in all browsers. Alt+233 gives me a theta but when I go to preview it turns into a question mark. I'm using Opera 7.23, FTR, and the only way it will let me post is using the &# codes either without previewing or by copying the post to the clipboard before previewing.

This sounds like you've configured it to force a character encoding other than iso-8859-1

It was on auto select. I tried forcing it to iso-8859-1 and the theta still turned into a question mark. *shrug*

For a full list of weird characters and the like:

1. Click on Start
2. Select Run
3. Type in charmap
4. Hit Enter

From there you can select what you want, then click on copy and it will automatically be copied to the clipboard. To put it in a post, simply press Ctrl + V.

with regards

I tried, and it doesn't work on my computer.

The chart with symbols appears, and I can click them too, but they never get copied to my clipboard. (There's nothing on my clipboard; when I go to another program, paste is not highlighted.)

If you are using Firefox there is a handy extension called abcTajpu that gives handy right-click menu with a ton of special characters. Just click and it inserst them.

I know there is an equivalent to "character map" on the mac, something-keyboard or something like that I think. At least there is keyboard in the name I think. It also tells you which key combinations will trigger a given character. It may take some work to find, check your applications folder.
