Hi, when i have multiple tables together the spacing between them is large and takes up unnecessary room. I have 5 tables which span the entire width and are one ontop of the other. If i was to put these tables into word they would fit into the one page. However, on latex the are spread over...

Hello guys, I'm trying to get some horizontal spacing into my text. I want to do this because I basically want to write a pseudo-code in my text, so I need every loop to start a bit further away from the beginning of the page than the previous one. I've tried \hspace, but it does not seem to...

Does anyone know a way to get half-vertical lines? I mean, I'd like something identical to /vline , but which starts from the top of the row and only goes halfway down. Similarly, I'd like a line which starts from the bottom and only goes halfway up. Even better would be something like a...

How do I write X bar with the bar over it to denote a vector? I discovered that if I compose a Latex equation here that I can copy it into a Word file. Is this true of all the symbols? Same for sub and super scripts. Is there a software tool that I can use to write Latex outside the realm...

I'm hoping someone can help me with the following problem. I have a .p file for generating a .eps file using gnuplot. I want both the y-axis label and the y-axis tics to be formatted using LaTeX. Getting this done is no problem. The problem I am having is that having both of these options...

Hello guys, I know this topic has been issued many times before. However I have an issue I can't find a solution for. I have a master file that calls another sub tex file using \include{}. This sub tex file has insert figures, I use insert figure options in the editor and the figures...

I'm trying to make a flipbook in the upper right of my thesis. I have already written it using a certain class (this class) and have tried to add the flipbook package. Latex says it cannot find flipbook.sty (FLIPBOOK) and I think there is some sort of friction with the class I am using. Is...

So, I have this equation: ^{137}_{55}Cs \rightarrow ^{137}_{56}Ba + e^- + \bar{\nu}_e What I don't like about it is that both 55 and 56 are left aligned and there is a gap between numbers and Ba symbol. I guess I could try to hand align them using spaces and negative spaces, but I also...

I have a fraction in the denominator of another fraction, and I'm trying to put a set of brackets around it. However, I can't seem to get them to size properly. Example below: Q_1 \left[ \frac{Q_2}{4\pi \left( r_2+\sqrt{ \dfrac{Q_2\gamma A}{4\pi}} \right)^2 } + Q_3 \right] which comes...

I want to indent everything after the first line, but not the first line itself. So it needs to come out like this: Physicsforums is a very interesting place where you can learn a whole lot and such and so and such and so. Is this possible?

i have come across quite a huge list of free math books from the project Gutenberg, they scan in old books. but theses have been converted to latex so they are REALLY nice to read. they even have links in the pdf. there is a huge list so take a look...

I'm working with a \documentclass[12pt,a4paper]{article} document and plan on adjusting the margins using the geometry package, but for this it would be handy to know an estimate of the current margin widths. Does anybody know them, or where I can find it?

Hello PF, I am writing my Thesis Report with Latex. Facing a couple of problems. 1. I want to create my report in verdana font. However, the warning states LaTeX Font Warning: Font Shape 'T1/verdana/m/n' undefined (Font) using 'T1/cmr/m/n' instead 2. After trying various procedures on...

Hello! I would like to write a multiline equation in latex Actually it is the last of these three subequations that needs to be split, but I can't work it out (neither for a single equation) though I tried a thousand split, multline, &quadd, \left\right\ and whatever commands. Is there an...

Hi all, I want to learn LaTeX and would like to know if there is a de facto standard for Windows-based editors. This seems like a good resource but honestly I don't really know which features I will prefer without ever using a LaTeX editor. I realize everyone will have individual preferences...

\begin{align} \frac{1}{4} &< (1 - u)^2 + \left(v + \frac{1}{2}\right)^2\notag\\ \frac{1}{4} &< (1 - u)^2 + \left(v - \frac{1}{2}\right)^2\notag \end{align} How can I make this on the complex plane with the appropriate area shaded? u is the real axis and v the imaginary

Hello PF, I am using MiKTex and TeXnicCenter for writing my Thesis Report. I want to add images (.jpg or .eps format) into the report. The last one I tried was, \usepackage{graphicx} \begin{figure} \includegraphics[scale=0.40]{121127332} \end{figure} What I get is just a empty...

Hello, I'm just wondering is it possible to put the units of a parameter underneath it rather than next to it. My table is pretty long and I could free up space if I could do this. For example, let's say I have Velocity (m/s) I want it to have (m/s) below velocity I can't figure out how to...

In the past few weeks, I have occasional trouble with my latex expressions (using the itex tag) running over the text that follows them. I also see this in some posts by others. Is there a good way to avoid this? Is it a browser specific problem? ( Mozilla and Firefox are mine.)

I want to know how can I have the latex system on a vBulletin forum. I searched for it but there was so little about it. Thanks

I'm not sure if this is a bug, or I am just an idiot and using this thing wrong, but when you click something in the LaTeX drop-down thing that appears to the right, for instance, a greek letter or something, the thing automatically inputs it where the cursor is, but includes a free set of itex...

I have a MATLAB figure I want to put in a document. I'm using MikTex and Texmaker. However in the past half hour I have not been able to get this to work using any format and I tried everything I found on google. If I try to use .eps/.pdf file, all the axis labels disappear. And .jpg is ugly. I...

Hello, I've recently been asked to submit my assignments using LaTeX and its really time consuming to have to type \begin{math} \end{math} every time I need to switch between English and math symbols. Can you suggest me a LaTeX editor that can speed up the process? (like with auto-fills...

MathJax has been upgraded to 2.0 today. Some members appeared to have problems due to cache conflicts. I've changed the CDN address and now it should be working smoothly. Take some time to look over "what is new". I'm sure you'll find some interesting new features. I am regularly in...

Is it possible to only show section numbers without chapter numbers in a LaTeX document of class "book"? For instance, Munkres' Topology text breaks things down into chapters but the sections are numbered independent of the chapter. For instance, Sections 1-11 are in Chapter 1, 12-22 in Chapter...

I have noticed recently that I will struggle with a math problem for hours, sometimes days, and then within five minutes of posting I will realize my error and resolve it myself. I think it has something to do with the crafting of the Latex code, previewing, repairing, previewing again, changing...

Hello, everyone! First time poster. Quick question: I am working in TeXShop on a Macbook. When I type $\nexists$, I get an error message saying "Undefined control sequence" even though it is in the list of short course symbol tables available under the Help menu in TeXShop. $\not \exists$ works...

what is the best book for a complete beginner to learn latex? I have a little bit of coding experience in MATLAB from a 1 semester intro course but other than that I know nothing about programming. I really want to learn latex though so I can take notes in math classes on my laptop :wink:

Use \displaystyle in the beginning for bigger expressions. Normal: $\sum\frac{n^5}{2^n}$ Using \displaystyle: $\displaystyle\sum\frac{n^5}{2^n}$

Can seem to make it work? Am I missing something? \begin{tablular}{c c c} P & Q & R \\ S & T & V \end{tablular}

If I have two strings of equalities within the same align or alignat environment, and the first one is long enough to need two lines, I would want the result to look like A+B+C=D=E =F=G=H I=J rather than A+B+C=D=E =F=G=H I=J Is there a way to do this? I suppose it can be done...

Can anyone tell me how i can wrap text around my figure in latex? I am trying to use the \usepackage{wrapfig} but it objects when i put this in. any idea why? any other suggestions? thanks

How can I get this to not wrap outside of my pdf $ \left(-\frac{1}{6 a}(-2 a (-2 + k) + \frac{2\ 2^{1/3} a \left(-3 + a (1 + k)^2\right)}{\left(9 a^2 (-2 + k)-2 a^3 (1 + k)^3 + 3 \sqrt{3} \sqrt{a^3 \left(4 + 4 a^2 (1 + k)^3-a \left(-8 + 20 k + k^2\right)\right)}\right)^{1/3}} + 2^{2/3} \left(9...

I am sorry guys - I don't have privileges to post in other sections of this forum. I am looking for a Latex program that shows the result of the code in real time so that I don't have to create a pdf every time I need to see if my code was correct. Any suggestions? Thanks.

It's strange no one has noticed but after reading through the Mathjax documentation guide, all you have to do to view the source code is right click over any Mathjax image and click "Show Source". A new window will pop up with the Latex code. Jameson EDIT: Try it here $ \displaystyle...

This can be very useful, so I thought i'd share. If you edit the > Wolfram Research\Mathematica\8.0\SystemFiles\FrontEnd\TextResources\Windows\MenuSetup.tr file you can make Strl+Shift+C copy not plain but in LateX format. Very useful. Look for the line in the file that says "&LaTeX"...

How can I put a Mathematica plot in my Latex document?

Kind of a non-issue but still bugging me. Basically, whenever I create a LaTeX file certain things will look a bit naff in PDF viewers, such as matrices will appear with the large square brackets broken in the middle, also text can appear bold when it isn't, dashes look odd etc. However, when i...

Hi, I'm wondering why my LaTeX output on PF appears in this font: http://img688.imageshack.us/img688/5020/screenshot20120129at123y.png Rather than the more typical one: http://img32.imageshack.us/img32/60/lateximage1.png Apologies if this has already been explained somewhere. I'm using...

I am interested in starting a Blog (not using PF Blog; nothing personal :wink:) on Mechanical Engineering related things. I will need to have equations and such, preferably LaTeX.
