## Latex Codes?

Hi everyone

I am a new member of this forum and I wonder how can I use those Latex codes for mathematical slymbol displays? I try typing those codes but it came out just the way I type them, do i need to install something before I can use those codes?

 Recognitions: Gold Member Science Advisor Staff Emeritus You don't need to install anything. You do need to use [ tex ] tags (without spaces of course). Have a look at this thread: http://www.physicsforums.com/showthread.php?t=8997 and the handy pdf: http://www.physicsforums.com/misc/howtolatex.pdf You can also see the source code of other latex images on the site by clicking on them.

I think its only available in certain forums such as homework and coursework.

Wow...
I just hopped over to a homework forum.
That sigma dropdown is gorgeous.
Any chance of someone (*cough* Hi, Greg! Have a chocolate!) adding that feature to other forums, as well?

I know that they are in the Relativity and General Physics forums.
I would guess that they are in some of the others science and math forums as well.
They seem not to be in the PF lounge (eg, Forum Feeback), the Technology forums, and Academic & Career Guidance.

 Blog Entries: 1 The Lounge doesn't really need it, and I doubt career advice does either. I'm no good with technology but I would guess it isn't really used in that either.

Your latex doesn't appear to have a white background to me.

 Recognitions: Gold Member Science Advisor Staff Emeritus I don't know SS, but I see latex in the background colour of the page not white. Somebody else asked not too long ago about the white background for latex. I'll have a look. post 27 onwards in this thread: http://www.physicsforums.com/showthr...x+white&page=3

Simple solution: Don't use Internet Exploder.

How, but how, do you manage to find all these stuff within minutes?

You yourself seem to have answered it in the thread Kurdt has given, in this this post.

 Quote by D H Simple solution: Don't use Internet Exploder.
Well, I have sunk to the level of using windows nowadays instead of good old Linux. Actually, I found IE to be faster than some of the other browsers. But it's IE 6.x. So, according to Hoot, upgrading to 7 will get rid of the problem. But it'll slower, naturally.

But there still remains the riddle of why I see old posts in the natural background. I'll have to fiddle around a bit more to see what's the cutoff date. Thank you all.

 Recognitions: Homework Help LaTex codes? You do not need to directly use them if you can use TexAide, which will work well on the forums. You still must supply the 'tex' tags for your coded notation to appear correctly. TexAide is a free program from Design Science Associates, the company who makes MathType. TexAide is very easy to use and you do not need to learn any special code (since TexAide takes care of that for you.)
