Quite often, I have lists with short items, e.g.:  \documentclass[a4paper,9pt]{scrartcl} \usepackage{braket}         % for \Set{}  \begin{document} adsfasdf \begin{itemize}     \item $\Set{A}$     \item $\Set{A, B}$     \item $\Set{A, B, C}$     \item $\Set{A, B, C, D}$     \item $\Set{B}$     \item $\Set{C}$ \end{itemize} test text tex \end{document}   which looks like this:    I know that I can get this with tables and three lists. But can I also achieve the same result simpler?
Let us consider The following example   \documentclass{article} \usepackage{enumerate} \begin{document} \begin{enumerate}  \item Which of the following numbers is the largest ?\\ $2^{3^4},2^{4^3},3^{2^4},3^{4^2},4^{2^3},4^{3^2}.$  \begin{enumerate}[(a)] \item  $2^{3^4}$ \item  $3^{4^2}$ \item  $4^{3^2}$  \item $4^{2^3}$ \end{enumerate}  \end{enumerate} \end{document}   This produces :    But I'd like to produce the following using the same package  :   OR     OR   How can I do that?
How to get distance when acceleration is not constant? I have a background in calculus but don't really know anything about physics.  Forgive me if this is a really basic question.  The equation for distance of an accelerating object with constant acceleration is:  $$d=ut        +\frac{1}{2}at^2$$  which can also be expressed  $$d=\frac{\mathrm{d}x}{\mathrm{d}t}t+\frac{\mathrm{d^2}x}{\mathrm{d}t^2}\frac{t^2}{2}$$  (where x(t) is the position of the object at time t)  That's fine for a canonball or something like that, but what about a car accelerating from 0 to cruising speed?  The acceleration is obviously not constant, but what about the change in acceleration?  Is it constant?  I suspect not.  And then what about the change in the change of acceleration, etc. etc.?  In other words, how does one know how many additional terms to add in the series?  $$d=\frac{\mathrm{d}x}{\mathrm{d}t}t+\frac{\mathrm{d^2}x}{\mathrm{d}t^2}\frac{t^2}{2}+\frac{\mathrm{d^3}x}{\mathrm{d}t^3}\frac{t^3}{3}+\frac{\mathrm{d^4}x}{\mathrm{d}t^4}\frac{t^4}{4}\cdot etc. \cdot ?$$ Setting or modifying a (system wide) environment variable in cmd.exe I am looking for a convenient way to add and/or modify and/or delete an environment variable from the command line. Particularly, I find myself at times in situations when I have to add a few variables in cmd.exe.  I'd be grateful if someone showed me a non-GUI way to modify (that is: to add a new directory to) the %PATH% variable.  The change should be be permanent, not just for duration of the cmd session. Drawing a triangle from medians Is it possible to draw a triangle, if the length of its medians $(m_1, m_2, m_3)$ are given only?  Someone asked me this question, but I can not see it. Is it really possible?  UPDATE  Apart from the algebraic solution given by JimmyK4542, can anyone give me a direct construction?  I mean, it should sound like:     Draw a line segment sufficiently long. Cut the length of $m_1$ from it. Then $\ldots$ Can anybody tell me when Application_End is triggered in a lifecycle of an application? When all sessions are ended, will Application_End be triggered automatically? + Are there any other reasons why Application_End could be triggered? Kill Command in linux Fixing the sucktastic merge UI (for tags) Change footer in beginning of chapters I want the footer of all pages to be "Page N°X" on the right.

How to prove that minimum of two exponential random variables is another exponential random variable? How can I prove that the minimum of two exponential random variables is another exponential random variable, i.e. Z = min(X,Y) A better answer was posted long after accepting another. Should I accept the new one? Why does this intentionally incorrect use of strcpy not fail horribly? I've got Ubuntu 10.10 installed to use my whole hard-disk, but would like to use the 130GB of free space I've got to create a new partition and do some development on Unity and Natty.  Can I use gparted to do this?  If so how? New phone: How to transfer game progress? I'm planning to buy a new Android phone and I'd like to be able to transfer the progress I have made at several games to the new device, so I won't have to play all the levels again from scratch.  I currently have an HTC Desire and will buy an HTC Evo 3D.  There's probably no simple/general solution to this.  But I was wondering if anyone did something similar and could provide some advice (e.g. where to look for files that might hold game progress information). How do I modify my PATH so that the changes are available in every Terminal session I want to add a directory to search my search path. I know I have to modify the PATH environment variable. However, I want the change to be permanent, so that it is always in effect, for every Terminal (bash) window I open.  There is an overload of confusing and possibly conflicting information in   I am using Ubuntu 10.04. Suppose I want to add /usr/local/foo to my PATH. Which file (.bashrc, .profile, .bash_login, etc...) should I modify and what should the new line(s) look like? Cube of an integer $\frac{x}{y}+\frac{y}{z}+\frac{z}{x}=k$ and $x, y, z, k$ are integers.  Prove that $xyz$ is cube of some integer number.    I was wondering about giving a parametrization for the rational points on the elliptic curve in $\mathbb{P}^2(\mathbb{R})$ $$ x^2 y + y^2 z + z^2 x = k xyz$$ but I am not too confident in the topic, so I am asking you to shed some light.  Thank you for your help. Connect two computers with SSH in a home LAN I have two ubuntu computer shared the same wifi and desire to reach another from one's terminal.

Wall of Sand on Difficult Terrain Looking into  prompted this inquiry:  What happens when you move through a wall of sand on difficult terrain?  This involves the understanding that wall of sand changes the cost of moving 1 foot to 3 feet and that difficult terrain typically changes the cost of moving 1 foot to 2 feet. What is the reasoning behind the design decision to allow users to create a display name which matches another existing users exactly?    This is opposed to the common practice of enforcing unique user names, and I'd really like to learn something. How to find the smallest $n$ such that $n^a\equiv 1 \pmod p$ Given a prime $p$ and number $a$, how do I find the smallest $n$ such that $n^a\equiv 1 \pmod p$? Is there a non trial-and-error method?  Edit: obviously removing $n=1$!
