LaTeX (hope no off topic here)

[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.
