Hi everyone, Maybe it's useful for someone who are not familar with latex but want to enter complex formulas. I suggest a new way to insert latex formated equations. I use LYX (www.lyx.org) ,it is a open source Latex WYSIWYG word processor. It will display the the latex code in another...

Hi, I have used latex generated equations in several forums and realize that there is a cutoff as to the number of equations that can be rendered, although I don't know what the limit is, i.e. I have just reach a point where it just fails. Tonight, I was trying to submit 3-4 equations, which...

Is it possible to define in LaTeX documents something like \ket{X} to be \left| X\right> so I don't have to type that every time?

Do you do it? I tend to not do it as long as it looks fine.

How to do that?

I know one the most common threads here are latex related, but would anyone have any good layout templates that they personally thought looked good or something they've come across? I'm toying with a prehistorically old template for my thesis and I'm not liking the look of it. Any help?

Hi all, I am planning to publish in APL (Applied Physics Letters). However, the RevTEX4 package that I downloaded from the website is too complex and you cannot choose APL from the journals. Does any of you have a template file for APL journal?

Hello, I have a problem with Latex. I use MikeTex as Latex distribution and TexnicCenter as editor. I want the code for a mathematical sentence with proof. I used the package ntheorem and I got the mistake: Waht did they mean with "already defined"? My code is...

Is there a symbol in latex for a divide bar that works with absolute values? The problem is for example if you want to write |a| divides |b|. It ends up looking horrible because you can't tell the difference between the abs value signs and the divide bar... |a| \vert |b| Any suggestions?

Hello, I am using the subfloat package. I have several images in my figure and I wanted to have an (a), (b), (c) under them and then refer to them like that in the caption. However, when I do ref {image1a} in the caption it shows up as "1a" instead of "a". I don't want the "1" because this is...

[tex]\int^fdx[\tex]

Hey there folks, Does anyone know if there are any email programs out there where you could embed latex commands much like in this form with the tex and /tex commands. I think it would be pretty cool if there were. Rich

I am having some trouble with the hyperref package in terms of it not actually providing links to my internal references. If I use the pdflatex command to compile my document to a pdf, the links work fine. However if I use the latex command to compile to a dvi and then dvi2pdf (or whatever...

Just say you are inside a lemma, which Latex automatically labels as Lemma 1. You'd like another lemma inside this one, call Lemma 1.1, what command do you type? How do you make it so that when a new paragraph starts, no indenting appears?

I want to be able to use latex but I do not know how ?help

Hi When posting, I am trying to display maths formulae using LaTeX. It is so much easier to read. When I hit 'Preview post' all I see is the raw LaTeX; [tex] 3i\theta + 2ik\pi = i\frac{\pi}{2} [tex] Is there something else that I need?

Check this formula: \sin(x) \] \cos(x) The \] there (click formula for source) seems to cause some strange indenting for sin(x). Is this a bug in the Latex formula generator?

To put my question in perspective, I'm starting grad school in the fall, and as an undergrad I was pretty sure I wanted to be a theorist so my range of experience with experiment is limited - I like reading papers off arxiv, and it's pretty rare to pull a theory paper that isn't typeset in...

Hi, I don't know if it's some mistake that I've been committing without realising it, but the Latex facility provided by this forum has given me no end of trouble. The following are two major problems I've faced: 1) Post preview generates a database error if there is too much latex in one...

I don't know if it's just me, but the latex code I've entered in https://www.physicsforums.com/showthread.php?t=242141" doesn't display at all, instead it's replaced by the invalid latex code red message. I checked the syntax and it seems to be all right. When I copied the Latex code and...

Hi I am first time user of LATEX. I have LyX editor where I am able to create LATEX documents. But I couldn't find any clear solution for pasting that LATEX content into my posts in the forum. Is there any simple way to copy LATEX document from the editor to forum posts?

I downloaded the TeXnic center and miktex and I have used them to produce very beautiful mathematical typesetting but I have never really understood how they are related. Can someone please explain what is the difference between latex and miktex, how they work together, whether I really need...

Hi all, I have a class file template which uses double columns throughout. I wish to insert a table which will fill the entire page so I need to somehow break the two column format for a small section and then go back to it afterwards. Does anyone know how to do this? Thanks in...

LaTeX is now in the blogs. However not in comments, but in entries. I want to again remind everyone who had a blog in the old system that you can recover those entries by going here: https://www.physicsforums.com/showthread.php?t=239834

All latex stopped working! I see the text "click to see latex code for this image" everywhere around the forums. I cannot know if something went wrong with my browser, or if this is a temporary problem with forum software, so I wrote this post to find out. Do others have the same problem now?

Ever since todays PF update, the LaTex button no longer appears on my toolbar. Is this a temporary problem? Jon

I am new to LaTeX typesetting, I have used it in this forum but I would like to use it to create a pdf. I use a mac, and I came across MacTeX from a google search. Can anyone validate this, is it good for beginners? Thanks,

I've not been able to find any sort of answer to this using google, but perhaps it's because the searches I've used have not been specific enough, so I apologize for bringing it up if this is answered on every LaTeX-oriented website. In any case, here's my setup: \begin{enumerate} \item...

For some reason, compiling my code gives me this wacky formatting error (see attached). The pages seem to alternate between too far to the left on page 1, too far to the right on page 2, left on page 3, right on page 4 and so on. Even my references are skewed to the right. Is there some sort...
