Remove margin in pages?
In version 5.2 of Apple's Pages app for OS X (Mavericks), how do I change the page layout?
Evaluating the integral $\int_0^\infty \frac{x \sin rx }{a^2+x^2} dx$ using only real analysis Calculate the integral$$ \int_0^\infty \frac{x \sin rx }{a^2+x^2} dx=\frac{1}{2}\int_{-\infty}^\infty \frac{x \sin rx }{a^2+x^2} dx,\quad a,r \in \mathbb{R}. $$  Edit: I was able to solve the integral using complex analysis, and now I want to try and solve it using only real analysis techniques. The -k option (or --convert-link) will convert links in your web pages to relative after the download finishes, such as the man page says:     After the download is complete,   convert the links in the document to   make them suitable for local viewing.   This affects not only the visible   hyperlinks, but any part of the   document that links to external   content, such as embedded images,   links to style sheets, hyperlinks to   non-HTML content, etc.   So, if I didn't specify -k, can I run wget again after the download and fix that, and if so, what would be the proper command? My guess is wget -c [previous options used] [url] and run it in the same working directory as the file were downloaded to. Possible Duplicate:          Is it correct to start a sentence with did.

Proving $\lim_{n\to\infty} a^{\frac{1}{n}}=1$ by definition of limit given a sequence $a_n=a^{\frac{1}{n}}$ for $n\in\mathbb{N}^*$, $a\in\mathbb{R},a&gt;1$ then proof that $\lim\limits_{n\to+\infty}a_n=1$ by definition.   proof:  given $a_n=a^{\frac{1}{n}}$ for $a\in\mathbb{R},a&gt;1$.  for $n\in\mathbb{N}^*,n+1&gt;n\Rightarrow \frac{1}{n+1}&lt;\frac{1}{n}$ and because $a&gt;1$ we gets $a^{\frac{1}{n+1}}&lt;a^{\frac{1}{n}}$, since $\frac{1}{n+1}&gt;0$, then $1=a^{0}&lt;a^{\frac{1}{n+1}}&lt;a^{\frac{1}{n}}\Rightarrow 1&lt;a_{n+1}&lt;a_{n}$.  then we proof that $\lim\limits_{n\to+\infty}a_n=1$ we need to show that $\forall\epsilon&gt;0,\exists N,\forall n&gt;N,|a_n-1|&lt;\epsilon$  then for $\epsilon&gt;0$, choose $N=\frac{1}{\log_a(\epsilon+1)}$, since $a&gt;1$ we gets that $$\forall n&gt;N,1&lt;a^{\frac{1}{n}}&lt;a^\frac{1}{N}\Rightarrow0&lt;a^{\frac{1}{n}}-1&lt;a^{\frac{1}{N}}-1\Rightarrow |a^{\frac{1}{n}}-1|&lt;|a^{\frac{1}{N}}-1|=|a^{\log_a(\epsilon+1)}-1|=|\epsilon+1-1|=\epsilon\Rightarrow |a^{\frac{1}{n}}-1|&lt;\epsilon$$  wich implies that $\lim\limits_{n\to+\infty}a_n=1\square$  my proof to the limit is correct?

The strange thing about the maximum in Planck's law I read that it makes a difference whether you calculate $\frac{dE(\lambda) }{d \lambda}=0$ or $\frac{dE(\omega)}{d \omega}=0$ in the sense that the maximum energy density with respect to the wavelength does not coincide with the frequency maximum that one would assume to be at $\omega_{max} = \frac{c}{\lambda_{max}}$. Actually, I do not understand why this is so ( Now, I am only interested in a pure physical explanation, mathematically this is clear and due to the chain rule). Does anybody know how to explain this odd thing?  Somehow I feel that the core of the question has not been completely answered. Although I can easily look up wikipedia, where the need for the chain rule is explained, I am rather interested in understanding where the following argument breaks down, which seems to be why this question has caused some confusion in the past(as you can see by googling this question):  So we have $E(\omega)$ the energy radiated at a given frequency. Now this function has a maximum somewhere, so there is a frequency where a maximal amount of energy is emitted. In other words: If you add the sum of the photon's energies at each frequency that are emitted, you will notice that the maximum is reached at this frquency. Now $E(\lambda)$ tells you basically the same for the wavelength, but again: We know where at which frequency the maximal amount of energy is radiated, so we know the corresponding wavelength.   I think there is a need to explain this.   If anything is unclear, please let me know. Does English have any singularia tantum besides mass nouns? and  are, respectively, nouns that have only a singular form and nouns that have only a plural form.  In English, we have a handful of pluralia tantum that are mass nouns which take the plural form (e.g. "riches" and "remains"), a whole load of pluralia tantum that refer to things that come in pairs (e.g. "trousers", "sunglasses", "knickers", or "scissors"), and at least one plurale tantum that fits into neither of the above categories ("clothes", meaning multiple items of clothing - it's clear what the hypothetical singular "clothe" would mean, yet it mysteriously isn't a word). Singularia tantum, on the other hand, seem less varied. As far as I can tell, they are all  - things like "information", "milk", and "racism".  One can imagine there being a singulare tantum that is not a mass noun. For example, we can imagine an alternate universe in which it is still correct English to talk about "a dog", but talking about "dogs" in the plural is incorrect and funny in the same way that it is incorrect and funny to talk about a "scissor". It might seem unintuitive to think that such a noun even could exist - surely, if it is not a mass noun, then people would just pluralise it with an "s" on the end like most other words? But the converse argument could just as well be made about countable pluralia tantum, and I still cannot go to a shop and buy a "clothe". Hence my question: do we have any such countable singularia tantum in the language? Have we in the past? Contains and Custom Label in Rule Criteria - Workflow I have a picklist field-XYZ which contains a lot of values.Lets say (A,b,c,d...z) I am trying to write a rule criteria which will execute if the picklist value is any of the following (A,b,c...p).So instead of mentioning all the values in rule criteria , i created a custom label and put the values (a,b,c,d..p) in that and wrote the following in the rule criteria :   CONTAINS(TEXT(XYZ__c) ,$Label.CustomLabel))   This is not working even is the value of the picklist is equal to the one mentioned in the Custom Label.I guess the CONTAINS function is matching the whole value of custom label with Picklist.Is there other workaround/solution for this? Assigning variables with dynamic names in Java Ctrl -C, Ctrl -V not working in different keyboard layout When I am in English, Ctrl+C, Ctrl+V works fine when I need to copy paste. But when I turn to Greek, Ctrl+C and Ctrl+V and basically no shortcut almost works in Greek.  So each time I have to alt shift and go back to English in order to user Ctrl+C to copy something. How can I apply this to the Greek keyboard profile?  EDIT  I also realized that when using NetBeans IDE 7.4,  I can copy and paste in Greek but I can't use the tonic system of the language over the words. In Aptana studio I can't use Copy and paste Ctrl+C, Ctrl+V When using gedit everything works fine. Different software use different keyboard layout settings? Did Harry Potter lose Voldemort's powers when he lost his connection to Voldemort? Harry noted to Dumbledore that he had a number of things in common with Voldemort. And it was later revealed that some of Voldemort's power was transferred to Harry when Voldemort tried to kill him. So, what powers did Harry get from Voldemort (i.e. Parseltongue and others) and did they all leave him when he stopped being a horcrux?    Update In the Chamber of Secrets Dumbledore states that Harry has many qualities that Salazar Slytherin values in his hand picked students. Parseltongue - resourcefulness - determination - a certain disregard for rules.    So, does anyone know what specific powers Harry got from Voldemort and is there anyway to tell if he lost anything else besides Parseltongue? Flag dialogs for grayed-out posts are also grayed-out Find the general solution of $y'= a^{x + y}$ where y is the function How should I approach this problem? Should I put ln logarithm on both sides and move factor of variable of lnx on right side in front of the ln, or do somehing else? I understand general solving and types of solving these differential equations of first order, but I have no idea what my next step should be. As many people already know, there are several ways to trigger Windows 7 Aero Snap feature. A user can either press Win+{Left,Right,Up,Down} to snap the window to the left or right or maximize or restore. One can also drag the title bar to all the corner except bottom one.  However, is there any keyboard or mouse shortcut to place one window on top half the screen, and another window on bottom half the screen? Please do not tell me to use "Show Windows Stacked" because if I have more than two windows, it will place ALL the windows horizontally, which is not what I want. I want to be able to select the window I want and place it automatically either on top or bottom half the screen.  Thanks!  Edit: Thanks for Moab's suggestion, both on recommend WinSplit and updating my question.  I should make it more clear that I'm looking for a software that will do the functions WinSplit provided, but with on screen input, such as touch screen or pen. Negative y value in polar plot I'm having some trouble with polar plots. I have to plot negative values, but without changing direction. I tried to set the ymin value to be negative, but it doesn't work.  \documentclass[10pt,border=10pt]{standalone} \usepackage{pgfplots} \usepgfplotslibrary{polar}  \begin{document} \begin{tikzpicture} \begin{polaraxis}[    xticklabel=$\pgfmathprintnumber{\tick}^\circ$,    ymin=-10,    xtick={0,30,...,330}] \addplot table{    0  -1     30 -2    45 -3    60 -4    75 -5    }; \end{polaraxis} \end{tikzpicture} \end{document}   Any suggestion?  For clarity, this is what I expected. Which infinity is meant in limits? For example, when we write $\lim_{x\rightarrow \infty} f(x)$ - which infinity is meant and why? Countable? If uncountable - which and why? I use a lot of lists and arrays but I have yet to come across a scenario in which the array list couldn't be used just as easily as, if not easier than, the linked list.  I was hoping someone could give me some examples of when the linked list is notably better.
