Hi! Is there possible to improve the quality of the images generated by latex code? It should be good if anti aliasing could be turned on, which would produce smooth and fine images. Now, the text looks a little bit awkward in my opinion, since it it all edged, and the small text is hard to read.

I can't seem to generate multiple lines within a single [ tex ][ /tex ] block. It's supposed to happen if I type \\ but it just never works for me. Example: f_1(x) = x \\ f_2(x) = 1-x^2 The "f2(x)" is supposed to start on a new line. What am I doing wrong?

How do I do a wide check symbol in latex? A wide hat or wide tilde is easy, it is simply \widehat{long expression} or \widetilde{longexpression} There is no command for wide check, i.e an upside down hat.

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...

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 finishing up a paper in Latex that I am writing for my internship and I am having a problem. For some reason, pretty much every other header is left justified one notch. i.e., if I have a header that is right justified, using \rhead{}, then on certain pages it shows up as center...

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...

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...
