Newbie needs EDIT time limit, LATEX help

[Gordon Watson]

What is the EDIT time-limit please? The "timed-out from editing" limit after posting.

 

Is there a latex sand-box (or external link) that matches the SFN coding requirement? I'm familiar with itex. And http://www.codecogs....x/eqneditor.php

 

But not all codings that work at "other physics forums" are happy here: see example below.

 

Help! Thanks, Gordon

 

((2s\cdoth/4\pi) \cdot (\delta_{a} \lambda\rightarrow \lambda_{a^+}\oplus\lambda_{a^-})\;cos[2s \cdot (a, \lambda_{a^+} \oplus\lambda_{a^-})])_Q = (\pm1)\cdot (s\cdoth/2\pi)_Q.\;\;(11a)^{11}

 

 

 

((2s\cdoth/4\pi) \cdot (\delta_{b}' \lambda'\rightarrow\lambda'_{b^+}\oplus\lambda'_{b^-}) \;cos[2s \cdot (b,\lambda'_{b^+}\oplus\lambda'_{b^-})])_Q = (\pm1)\cdot (s\cdoth/2\pi)_Q.\;\;(11b)^{11}

The editing time limit is ten hours. You can use the Preview Post feature to play with LaTeX -- enter some LaTeX, hit Preview Post, and see what comes out -- or you can use the LaTeX Whiteboard:

It uses the same LaTeX system as the forums do, so anything that works there will work here.

Using "\cdot h" instead of "\cdoth" seems to fix it.

Thanks for this!

 

Then I next I had big problems when formatting equations in http://www.sciencefo...ed/#entry677673

 

A small change to an equation at the top produced consequences in paragraphs at the bottom of the page. Also, attempting to have uniform equation spacings changed the text spacing in paragraphs further down.

 

I'm doing something wrong here. No problems from old forum; must be some rules I'm missing? More help would be appreciated.

 

With thanks again, Gordon

YES, it was as simple as that! Great! Many thanks; and wondering if you can help with my page formatting problems, please? See my earlier thankful reply to Cap.

I'm not sure what you mean. Changing the LaTeX at the top shouldn't change anything later. Now, putting LaTeX in paragraphs will make them spaced funny, because the equations are taller than normal text, but there's not much that can be done about that.

Thanks. Sorry. No. The LaTeX was fine: the problem occurred when formatting the spacing between the LaTeX-formatted equations; trying for the "normal" uniform spacing -- knowing about your point -- which spacing is still not there. But I left it because edit time was running out.

 

I'm gonna look at the source coding (better if an expert did THAT but) BUT I'm confident there was a bug to do with the "return" key action: which is what I normally use for spacings?

 

In short: Just look at the grouping there and realise I wanted it like (1)-(6) right through. AND THAT at one stage they were all like that EXCEPT one: It was then, "adjusting" that ONE, that the drama unfolded; including in lower paragraph spacings. Help. Thanks.
