LaTeX Why is LaTeX malfunctioning when I type in equations?

[Femme_physics]

I keep typing things and getting not the things I typed in LaTeX. Am I the only one?

Look at what I'm typing here


AD = x^{2}+(4-2x)^{2} AD = x^{2}+(4-2x)+(4-2x) AD = 2x+(-2)+(-2) AD = 2x-4

I'm getting

AD = 2x-4x

and I'm typing in LaTeX all of that (with the tex /tex function-- I believe that if you click "quote" you will see that):


AD = x^{2}+(4-2x)^{2} AD = x^{2}+(4-2x)+(4-2x) AD = 2x+(-2)+(-2) AD = 2x-4

Okay, something weird happened just now. The preview show something else. And now it corrected itself. Seriously, it's as though there's a delay with LaTeX or something.

I guess you refer to known problem - preview doesn't show what it should show. Try reloading the page or just the picture. This has been discussed zillions of times, and it will not change till Greg decides to replace LaTeX engine.

Oh, sorry, I thought I'm special. My bad. :)

I'm glad you posted. I was just looking to see if others were having the same problems as me (like Greek letters being superscripted and previews show Latex I used in previous posts). Your post gave me a swift end to the search.

There's at least 20 threads about this. You could have found them e.g. by searching the feedback forum for threads with "latex" in the title.

Test: x = \frac{-b \pm \sqrt{b^2-4ac}}{2a} \quad \text{Quadratic Formula}

I noticed that MathJax scripts are being called in the source; seems like still using the old LaTeX system for now...

I was tinkering but ran into an issue. I'm looking to phase in MathJax in June.

Sound good. Thanks for putting all the work into keep PF running!

Mathjax calls were a problem about 9 hours ago - now and then Opera was waiting for mathjax servers and in effect pages were loading quite slow.
