Is there any kind of reader where I can enter the formulas such as "x\left(\Psi^{*}\frac{\partial\Psi}{\partial x}-\frac{\partial\Psi^{*}}{\partial x}\Psi \right)\right|^{+\infty}_{-\infty} = 0?" described above and have it in shown in a clean way please?

This is my first post. The sticky on Latex is very useful. Looks like I will be learning the code for formulas. Would like to know if you can test the code without posting to the board - how to play with the code and view results locally first. I am also trying to attach an image. Darn -...

How would I go about to write in latex (not the PF version, the actual thing) a function? By that, I mean when you go f:A\rightarrow B a\mapsto f(a) but how to write the code so that the arrows are all just right in length? Thx!

Many journals encourage authors to use their special latex packages (e.g., revtex4-1 for physical review a,b etc) while sending an article for peer-review process. I am not sure if this is compulsory or optional. Will an article be rejected if it is written not using the special latex packages...

Hi. As I currenhaven't got the internet, I occasionaly download pages from cafe and read at ho9me. But I can't see the equations, only the code itself. This has been hapening for some time even with the latest IE. What am I missing?

First, how and where did you learn LaTeX? I want to get started, but I have been shocked at how unhelpful the resources at the top of my Google searches have been. Second, what applications do you write and compile in? I've heard of "Emacs," but I'm not sure if this is as related as I would...

Why do I only get page numbers on page 2 and not the abstracts? And then it starts over again with page 1 on the first page in the TOC...And then it starts over again on the first page of the first chapger... \documentclass[12pt,a4paper]{report} \usepackage{epsfig}...

I just was wondering what is the meaning of this symbol \stackrel{\smile}{\frown} . It is used in the terminology of estimation of norms, I do not know if it is a standard notation, since I did not find anymore explanations. Also I do not know if there is a command to write it directly by...

On my newer computer, the Latex displays pretty decently. (Not as good as on the ipad though.) On my older computer, the Latex displays pretty crappily, rough around the edges and so forth. What determines the clarity of the Latex display? Is it the graphics card in the computer? or are there...

Dear all, I'd just like to know if it's possible to add let's say line on float with Latex. I use textpos package to add text but what about drawing? Thanks, Éric.

Hi I know latex but need to know the template used by physics teachers for final exams ? Can anybody guide me ? there are many options in latex, which one is used for setting up exam papers ? thanks

For about a year and a half now, I've been writing down stuff I've learned into a bunch of LateX files, to make it easy to refresh my memory when I've forgotten something, and perhaps also to be able to show some of it to other people at some point. In order to make it look nice, I chose to use...

What is this kind of diagram actually called? And how does one produce this in latex?

I'm running in the report document class and I was wondering how does one make the table of contents single spaced? Or possibly even 1 1/2 spaced. I tried some suggestions involving the tocloft package and everything pretty much went to hell. Due to some annoying issues with how the theses need...

Using LaTeX at Physics Forums Getting started: Those fancy mathematical symbols are being made with something called LaTeX. It's easy to include LaTeX code in your posts at Physics Forums. You just need to type the LaTeX code that produces the formula you want between [itеx] and [/itеx]. For...

Dear Forum I would like to establish a workflow of how to include .eps graphics generated with gnuplot into Latex documents and it would be great if other could contribute to this. At the moment its like this. I plot some data with gnuplot and save it to a .eps file. However, the "white-space"...

Folks, I find it very tedious writing using latex symbols on this forum, i.e. I continually have to click ‘preview’ to see that the equations turn out ok before submitting. Is there some compiler I can use that generates the math independently of this forum then I could copy and paste onto...

I realize this is most likely an extremely basic question but I can't seem to find the answer... I am wondering if it's possible to convert MS Word documents (with some MathType equations) into LaTeX (and then into pdf files)? I have never used LaTex before and would appreciate some basic...

It takes longer to write out a question and your working, than it does to even get a reply.. And that reply either never comes or is something along the lines of 'I can't tell what you've done'. Latex is so harsh to use, is it possible to install something to mirror microsoft word equation...

I've been using Latex for many years now. But there is a feature which I feel more and more uneasy about: At least in plain latex you are supposed to do subscripts, minus signs, in math mode, even when writing a simple number with exponent in text mode. Another example would be expressions like...

I want to make a poster on latex with a Mac, I already have the Latex package for mac but I don't know what is the procedure to make a poster on latex. Can somebody give me a reference? Or any kind of help.

Can someone tell me if the 1st edition of The Latex Companion is pretty much still usable in terms of learning the details of using latex? It's 17 years old and I know this is probably something that isn't constantly changing but I'd just like to get everyones opinions. I tried using bibtex...

Hi all I use Lyx v1.65 for creating LaTex. Obviously it displays OK in Lyx. It also displays OK with an online editor I've tried http://www.codecogs.com/latex/eqneditor.php But invariably when I try to post LaTex to this forum it does not work. I've tried the sandbox which the reason...

I want to have a section title to the effect of "Pseudocode for the Func1 Function," but I would like "Func1" to be in typewriter font to indicate that I'm referencing programming code. Is there any good way to do this? The verbatim and verb commands don't seem to work. Thanks.

I'm not totally sure this is the right place to put this but here goes. I am using a thesis package from a different university for my thesis and I am having an issue with the line spacing. The vertical spacing between equations is a bit much. How exactly can I change this spacing for the...

Hi everybody, I've got an issue, and I would like your opinion. I'm a PhD student writing a paper, I'm the first author, I've got the idea, I've done (lets say) the 90% of the labour. The method section has a lot of formula, and I'm happy to write it in LaTeX using the templates from the...

y_2 = y_1 * \int^t ( 1/y_1^2(s) * exp(- integral[.. to (s)]( p_1(z)dz))) is there a page on this site on how to make this crap work?

This doesn't work properly: \begin{array} \frac {\partial}{\partial a^1} = \cdots \\ \frac {\partial}{\partial a^2} = \cdots \\ \frac {\partial}{\partial a^3} = \cdots \end{array} It gives \begin{array} \frac {\partial}{\partial a^1} = \cdots \\ \frac {\partial}{\partial a^2}...

Hello everyone You see I create a small website about physics in my country, Poland... And I have one page where pattern are (you now - formulas, in polish wzory).. I use latex as You use on Your page... The only thing is that latex is very very slow...

I recently deleted my Latex code for my dissertation and now I'm starting from scratch. In my last code I had a line of code at the beginning that does all of my auto fitting for brackets, fractions etc. without having to worry about using \Bigg etc. but I can't seem to remember what it is, I...

I'm writing a final report, and I've got a bunch of source code that I'd like to have readily available to anyone reading the document. I won't have any control over the files once I hand it in, so I'm a little wary about just putting everything in the same folder and trusting that everything...

Once upon a time I could click on a LaTeX image and a new window with the code used to generate the image would pop up. This was super useful in learning LaTeX. This function gone?

I haven't been on this site for a long time. Is Latex typeset a feature of physics forums or do I have to download it onto my computer?

I tried using site, https://www.physicsforums.com/mathjax/test/preview.html but after putting in the codes and pressing enter, nothing happens. I will test by trying the code tags here: \frac{x^2}{a^2}+\frac{y^2}{b^2}=1 \frac{x^2}{a^2}+\frac{y^2}{b^2}=1 For reference, I used...

I am looking through all sorts of tutorials and I could swear I am doing this right. But obviously not. The source code compiles and generated the PDF just fine, but no citation number shows up (just ?? in stead) and no bibliography section is generated. Here is a sample code. I know the...

Hi all, I have an odd problem with a table that refuses to grow vertically, instead, it just wanders off over the righthand edge of the page with each row only one line in height. I have other tables constructed after the exact same method as this one, but they do grow vertically. Confused...

Hi guys, I have to do a lot of equations in a report, and I was wondering if there is a package for Latex so that I can just cut and paste matlab/excel coding straight into Latex and it will set it out properly. i.e. so that instead of typing \frac{5+x}{4} I can just write (5+x)/4?

Hi guys! This should be a no brainer, but I am having troubles. I downloaded the 2011 version of MacTex. It comes with TexWorks and TexShop. When I double click on .tex files, they open by default in TexWorks, but I want them to open by default in TexShop. It should be a simple matter of...
