LaTeX Why Can't I Preview LaTeX Math Notation on Forum Posts?

[BarbaraDav]

Dear Sir or Madam

I'm a novice here thus I'm probably going to ask a silly question
(in a bad English, moreover). Please, can you explain the reason
why I can't get the mathematical notation ( \alpha , as
an example) displayed clicking on "Preview post" button ?

I have been looking around for a "sandbox" to try some tests but
none was found.

Warmest regards.

Try this page of this thread, I stumbled across it and it has a lot of sand box testing on the whole thread, plus there are a few programs there which will let you try it out.

\alpha

Also I've noticed left clicking on any latex, brings up the code. Try that.

If it won't display then it might be a problem with your browser, could be anything, try refreshing the page, works for me, sometimes I end up with some really odd previews and or posts, but on hitting refresh it usually clears it up.

Thanks for your reply! In the page you pointed to, I see the equations and the their LaTeX code also, but, as far as I understand, there is no way to have a try there. Anyawy, supposing that standard LaTeX 2.09 "is spoken" in this forum, may be the easiset way is simply copy and paste from inside a visual editor such as Scientific Workplace. I'm goingo to check.
Best regards.

P.S.
Sorry for my Engish.

On the page I posted there are at least two sand box URL's you can use to practice. And don't worry my English isn't great either and I am English.

Try these:

This one requires you to use $ tags either side of the Latex.

This one let's you type in the bare code.
