I need to write a task assignment (a paragraph ordered by enumerate) and attach a solution (possibly using hyperref technique). That's clear. But now I want the task solution to be placed at the end of the document in PDF but next to the assignment in the code.  What would be the best option to do so?  Example:  \begin{document}  \section{Tasks}  \begin{enumerate}   \item \label{Newton} How many apples fell on Newton's head?     %Here should be a code: How the hell should I know?   \item \label{Archimedes} How loud screamed Archimedes "Heureka"?     %Here should be a code: How the hell should I know? \end{enumerate}  \section{Solutions}  %Here should be an automatically created list of previously commented content.  \end{document}
How can I produce exercises in one part of a LaTeX document with selected answers in another? I could, of course, simply typeset the questions and the answers separately, but this is too likely lead to divergence in the labels for the questions and the answers as the document is edited.   What I'd really like is a command that would allow me to typeset exercises at the point at which the command was used and which took an optional argument for a solution to be stored until a final section (chapter, or part) "Selected Exercise Answers". I'd like the questions (and the selected answers) to be labeled in the output by Chapter.Section.Question or even Chapter.Question.
Should we put the references in slides/poster when we already have them in paper? After reading this question about  and asking myself two questions about  and , I realize that these activities are for showing what you found, make the audience be attracted. If they need further explanation, they should read your paper, which has successfully defensed and proved that your work is validated. One important thing when you attempt to attract people is concentrate on the important, which means unnecessary things need to be trimmed. I think the reference is one of those. So, should we put the references in slides/poster when we already have them in paper? How to disable Excel number autoformat Can somebody give me an example of a graph on eight vertices that has a pair of pseudosimilar vertices? Or, is it not possible? If it is not possible, please do not give me a proof, as I would like to figure out how to prove it myself.     Definition: vertices $u$ and $v$ in a graph $X$ are similar if there is an automorphism of $X$ that maps $u$ to $v$. If $u$ and $v$ are similar, then the vertex-deleted subgraphs $X-u$ and $X-v$ are isomorphic. If $X-u$ and $X-v$ are isomorphic but $u$ and $v$ are not similar, we say that they are pseudosimilar.

I'm trying to wire up 6 RGB LEDs in parallel, all controlled from a single source (well, three sources, one for each colour). The LEDs came supplied with resistors to limit the current of 270 Ohm for a 5v supply.  The problem is, 6 LEDs x 3 colours = 18 resistors, which is a lot, and means I need a much bigger board and a lot more soldering.  So, can I instead wire the LEDs in parallel with each other, with a single resistor protecting all six? (3 resistors in total, one for each colour). How do I calculate the value of that resistor?  More details:  The LEDs are being driven from a  to supply a bit of current, which is in turn controlled by a Netduino providing a PWM signal on the three channels.  . If I've correctly understood the data sheet they want 20mA of current, and forward voltages of 2, 3, 3 volts (for R,G and B respectively?). The supplied resistors were all 270 Ohm, so the channels may not be balanced quite right.  For extra credit: I'm only using 3 of the transistors in my driver chip, which has 8 in total. could I wire the PWM from the netduino to a second trio of transistors, and split the LEDs into two groups of three? Is it worth the effort?  PS I don't have any diagramming tools to hand, but I can provide a diagram (drawn in paint) if it would help clarify my question. (see also ) For each of the following, give an example of a sequence of functions $f_n$ that converges to f  A. uniformly but not in the mean square sense.

Given a finite field $k$ and some irreducible polynomial $f(x) \in k[x]$, then $k_f \cong k[x]/(f(x))$? I know that it's true if $k$ is the prime field and I think that the statement is not true for general finite fields, however I could not find any counter example.  Thanks in advance. How to grep for text in a file and display the paragraph that has the text? How do malloc() and free() work? I read a book a while ago in which a device is invented which opens up "tunnels" back through time. These tunnels cannot be traveled through, but can be used to view what happened in the past. I believe it starts out narrating the invention of the device, then skips ahead to after it is widely in use. There is another device created, a cloak of sorts,  which hides the user from the view of someone using the tunnel device. Does this ring a bell with anyone? Switch from single to double column in the same page So I decided to install my copy of Ableton (v9.1) on my computer now that I've upgraded to a machine that isn't ancient. HOWEVER Despite WineHQ reporting that Ableton is platinum-certified, I can't get the dern thing to open.  It crashes out just as the splash screen pops up.  Sometimes I see it, sometimes not.  It tells me that some catastrophic error has occurred, and it needs to close.  I've tried this on two different systems running two different versions of wine  (One runs the up-to-date public distro 1.6.2, while the machine I actually want to install it on is running the 1.7.19)  I don't know what to do.  I'd really just like to get this working, as my friends really like the look and feel of Ableton, and I really don't like LMMS (Linux-y free Audio Software).  Any idea what's going on here? I've found a couple of other people who seem to be having the same problem as me, but no dice on any solutions.  None provided, really.

Proving $\sum\limits_{i=1}^k | \langle x,v_i \rangle \langle y,v_i\rangle| \leq \|x\|\cdot \|y\|$ Let $V$ be a real inner product space, and let $v_1,v_2, \dots ,v_k$ be an orthonormal set of vectors. How do you prove that  $$\sum_{i=1}^k | \langle x,v_i \rangle \langle y,v_i\rangle| \leq \|x\|\cdot\|y\|?$$  When does the equality hold?  I've been trying to do this with the Bessel and Cauchy-Schwarz inequalities, but I can't make it work yet. Any help would be greatly appreciated.
