LaTeX and Spoiler

LaTeX dont work with Spoiler. Why ???

Re: LaTeX and Spoiler

The spoiler tags here don't seem to do anything more than to change the color of the text to the color of the background. This doesn't affect images. I don't know why the spoilers are so primitive here. I have seen at least one other forum (that also uses vBulletin) where stuff in spoiler tags is really hidden until you click a link to show it.

Re: LaTeX and Spoiler

this is a test disregard

latex code \\Delta x fluck!!!

[ tex ] a^x_n [ /tex ] this is not flucking fair i copied that directly from the help thread!!!

[ tex ] a^x_n [ /tex ] this is taking all the fun out of math fluck!!!

$$a^x_n$$ why did the help thread not state that no spaces were allowed inside the tex brackets like this [ tex ] a^x_n [ /tex ]

ok now that i have conquered the demons of a bad latex parser let me try delta x

$$Delta x$$ do not give up

$$\Delta x$$ yes!!!

Re: LaTeX and Spoiler

I guess you missed the warning in boldface right before that example: The real tags do not include spaces.

Remove the spaces that are inside the brackets, i.e. immediately before and after the "tex" and "/tex".

[added] Ah, now you figured it out! :smile:

Re: LaTeX and Spoiler

You don't have to post your experiments. Just use the preview feature, and keep in mind that the only way to work around the bug that makes the wrong images appear in previews is to refresh and resend after each preview.

Re: LaTeX and Spoiler

there is one more problem ... the preview button don't refresh the latex code

it shown the old one ... the very first one i ever used .... unless i delete all cookies

 Fredrik Mar31-11 12:38 PM

Re: LaTeX and Spoiler

That's the problem I was talking about. Deleting the cookies won't help. You have to refresh and resend after each preview.

it helped me

Re: LaTeX and Spoiler

I don't think it did. You probably refreshed the page as well. As far as I know, the problem is the same in all browsers and all operating systems. The only thing that works is to refresh and resend.

Fortunately Greg is planning to install MathJax in a few weeks, and that should solve the problem once and for all.

Re: LaTeX and Spoiler

no ...

like if i used code which gives preview as: $$\frac{Use}{less}$$ on say 14march

and on 15 march i write latex code [ tex ]\frac{still}{useless}[ \tex ]
and hit preview
it will still show me $$\frac{Use}{less}$$

Re: LaTeX and Spoiler

You haven't understood what people are telling you do do.

Write your new LaTeX. Preview it. Sure, the display is usually wrong.

Then hit your browser's REFRESH button. That will fix the display.

 Fredrik Apr1-11 11:18 AM

Re: LaTeX and Spoiler

Exactly. You have refresh and resend after each preview.
