I have Date in SharePoint server 2013 and I want to add 14 days on it by jQuery   I have the column name EndDate text type.
I have End Date column and I want to add 14 Days on it auto when created, can I do it by workflow? Can I do it via jQuery. If yes how? if no how I can do it?
Prove $ \sin x + \frac{ \sin3x }{3} + ... + \frac{ \sin((2n-1)x) }{2n-1} >0 $ Prove that for $ 0&lt;x&lt; \pi $, $$ \quad S_n(x) = \sin x + \frac{ \sin3x }{3} + ... + \frac{ \sin((2n-1)x) }{2n-1} &gt;0 \quad \forall n = 1,2,... $$  Having trouble with this problem. This is an olympiad-style question, so an answer that doesn't use calculus or analysis would be preferred. A possible approach is induction, but for this we need to find a function in terms of $n$ and $x$ so that we can actually use the inductive step. If anyone has any ideas they would be appreciated.  If you really want to go down the calculus route (at this point I don't mind), then $ S_n' (x) = \cos x + \cos 3x + ... +\cos((2n-1)x) $ , which you can find a closed form for, but I don't know how useful that is. How to find out who deleted some data SQL Server My boss had a query from a customer yesterday asking how they could find out who deleted some data in their SQL Server database (it is the express edition if that matters).  I thought this could be found from the transaction log (providing it hadn't been truncated) - is this correct? And if so how do you actually go about finding this information out? Does 'rm .*' ever delete the parent directory? The expression .* is expanded by bash to include the current and parent directories:  $ ls -la total 2600 drwxrwxrwx   2 terdon terdon 2162688 Sep 10 16:22 . drwxr-xr-x 142 terdon terdon  491520 Sep 10 15:34 .. -rw-r--r--   1 terdon terdon       0 Sep 10 16:22 foo $ echo .* . ..   If I run rm -rf .* on my Debian using GNU bash, version 4.2.36(1)-release and rm from rm (GNU coreutils) 8.13, I get this message:  $ rm -rf .* rm: cannot remove directory: `.' rm: cannot remove directory: `..'   Is this a GNU thing or is it POSIX? Are there any *nix systems where the command above will silently delete . and ..?  Also, is this a safety feature of the shell or of the rm command itself? Is every invertible matrix a change of basis matrix? siunitx uses math mode for symbols - workaround needed when using different fonts for math and text This is a follow up question from . The original problem has been solved using siunitx instead of dcolumn. However, the problem is that I am using mathpazo with osf as my main body font and eulervm as my math font. With siunitx used to decimal align tables this results in []() symbols being drawn in the math font, but the digits being drawn in the text font, as the following MWE example illustrates.  Is it possible to draw the symbols in the normal text font or redefine the mathfont for S columns completely?  \documentclass{scrartcl} \usepackage{booktabs} \usepackage[osf]{mathpazo} \usepackage[euler-digits]{eulervm}  % For Tables created by estout \newcommand{\sym}[1]{\ensuremath{^{#1}}} % for symbols in Table \usepackage{siunitx} \sisetup{ detect-mode,            group-digits            = false ,           input-signs             = ,           input-symbols           = ()[]-+ ,           input-open-uncertainty  = ,           input-close-uncertainty = ,           table-align-text-post   = false          } \begin{document} \begin{tabular*}{\textwidth}{     l @{\extracolsep\fill} *{2}{S[table-format=4.4]} @{}} \toprule \multicolumn{1}{@{}l}{\emph{Age}}  \\[0.5ex] 18--24 &amp;   [-1360.228]\sym{*}  &amp;  -1371.941\sym{*}  \\        &amp;       (6.915)         &amp;    (-7.953)        \\ 25--34 &amp;     -219.216          &amp;   -240.271         \\        &amp;     (514.894)         &amp;   (515.348)        \\ 35--44 &amp;     -310.715          &amp;   -311.438         \\        &amp;     (485.780)         &amp;   (486.013)        \\ 55$+$  &amp;       -5.135          &amp;     [2.656]        \\        &amp;      (53.267)         &amp;   (533.875)        \\ \bottomrule \end{tabular*} \end{document}   Edit: Thanks to David the problem has been solved including a fix for amsmath and extending to XeTeX.

Checking out  and  (and some papers) was a bit difficult for understanding Group Action. The closest to understanding was this part:    I understand the definition of homomorphism (a structure-preserving map between two algebraic structures of the same type). And from what I understand the symmetric group is a group of functions (bijective functions) mapping elements of a set $X$ onto itself.  However I get confused at this line:     ...an action of $G$ on $X$ may be formally defined as a group homomorphism $\phi$ from $G$ to the symmetric group of $X$.   That seems to be the definition of group action, but I am having trouble understanding how to apply that.  What that says to me is it is a homomorphism (function) $f \colon X \rightarrow S$ where $S$ is a set of bijective functions on $X$. That itself seems weird, I thought a group action would result in a number or something related to $\{1, 2, 3\}$ (defined next).  Continuing, if we have a set $X = \{1, 2, 3\}$ and a group $(*,\{4, 5, 6\})$, then the symmetric group of $X$ would be something like $S = \{1 \rightarrow 2, 2 \rightarrow 3, \dots \}$, and $\phi$ would be something like $f : \{4, 5, 6\} \rightarrow S$. That doesn't make sense to me and I feel like I'm interpreting something wrong. I don't see how mapping to a set of functions $S$ will result in an action on the set. Replace strings in a file based on a list of strings and a list of corresponding replacements Suppose $\sum a_n$ converges absolutely and $\sum b_n$ converges. Give an example where the Cauchy product does not converge absolutely. I am not very familiar with databases and the theories behind how they work.  Is it any slower from a performance standpoint (inserting/updating/querying) to use Strings for Primary Keys than integers? My question is really ''what is the definition of a conservative vector field''?  I've consulted 3 textbooks that all say a vector field $\vec{F}$ is conservative by definition if there exists a scalar potential $\phi$ such that $\nabla \phi = \vec{F}$. Then, they go on to talk about connected domains, path independence and the equality of mixed partials and how they are all related.   In particular, they emphasize that e.g. in $\mathbb{R}^2$ given $\vec{F} = \bigl&lt;F_1,\,F_2\bigr&gt;$, if $\frac{\partial F_1}{\partial y} = \frac{\partial F_2}{\partial x}$ on a simply-connected domain, then $\vec{F}$ is conservative on that domain.  However, without fail, all of them then offer the example of $\vec{F} = \bigl&lt; \frac{-y}{x^2+y^2},\, \frac{x}{x^2+y^2} \bigr&gt;$, pointing out:   it's line integral is not path independent, even though $\frac{\partial F_1}{\partial y} = \frac{\partial F_2}{\partial x}$   and this is explained by pointing out that the domain is not simply connected (if the path contains the origin).  That much makes sense to me: we cannot conclude $\vec{F}$ is conservative based on the partial derivatives, because the domain is not simply connected - totally consistent with what has been presented.  What none of them address is why $\vec{F} = \bigl&lt; \frac{-y}{x^2+y^2},\, \frac{x}{x^2+y^2} \bigr&gt;$ is not conservative when there exists a potential $\phi = \arctan(y/x)$ such that $\nabla \phi = \vec{F}$. None of the texts mention any necessary conditions on the scalar potential. So is the existence of a scalar potential the definition of a vector field being conservative or not?

If I'm logged in to a system via SSH, is there a way to copy a file back to my local system without firing up another terminal or screen session and doing scp or something similar or without doing SSH from the remote system back to the local system? In PHP, how do you change the key of an array element? Complex integration with a $\mathcal{C}^1$ function $f$ Classifying whether a collection of objects is a set Do neutrinos not couple to the Higgs field? I was reading the CernCourier, my favorite source of message on Higgs and friends. I was rather shocked, when I saw this:     "The mechanism by which neutrino mass is generated is not known."   What? Not known?  says: In Higgs-based theories, the property of 'mass' is a manifestation of potential energy transferred to particles when they interact ("couple") with the Higgs field, which had contained that mass in the form of energy.  Does this mean that neutrinos don't couple to the Higgs field? Is there any way, shape, or form that ultraviolet light is recorded by a digital sensor?  Ideally, this question is related strictly to the sensor, without even a glass lens in between which could cut or block UV light.  But of course I don't take pictures with a bare sensor, I also have a lens, so I'd also like to know how much UV gets to the sensor to begin with. I was using , implemented in scikit-learn, for my research work. But I have no good understanding of this.   Can anyone please give a simple, good explanation of one class SVM? My processor is an Intel Core 2 Duo P8600 (2.40GHz). As far as I know that's a 64-bit processor - I'm a bit confused as the architecture is called AMD 64, is this a generic name given to 64-bit architectures? I've heard of x64 but can't see a release labelled with this.
