 Nov3 awarded Yearling Oct15 comment TeX editor with instant preview @Moronplusplus I have probably deleted that file off the server, I can reupload it if you like. Sep30 awarded Explainer Sep24 awarded Autobiographer Jul3 comment Why $2x$? Can't it be $x$? What about $x=2.5$ or $x=\pi$? Addition in $\mathbb R$ cannot be defined via a sum of $n$ summands easily. Jul2 awarded Curious Feb9 revised $\theta_1 + \theta_2 = -35.5$ how to find the values of those $\theta$s? fixed latex Feb9 suggested approved edit on $\theta_1 + \theta_2 = -35.5$ how to find the values of those $\theta$s? Dec15 comment Prime decomposition over the real numbers? Remember that I basically "choose" my prime elements and do not acquire them via divisibility rules - $\frac{1}{x}$ can just be defined as one, or else be the product of other elements in $P$. Dec15 comment Prime decomposition over the real numbers? @edit - why would it give problems to have $\frac{1}{x_i}=x_i^{-1}\in P$? I really dont see that argument... Sorry if these objections are useless, but im trying to understand the matter. Dec15 comment Prime decomposition over the real numbers? Sorry for taking away the accept for now, I would like to know: am I really trying to show that? The fact that each number is a unit gives problems usually, since each element $x$ can be written as $x y y^{-1}$ - I take out this case purposefully Dec15 asked Prime decomposition over the real numbers? Nov22 awarded Favorite Question Nov9 awarded Notable Question Nov3 awarded Yearling Sep1 comment Jigsaw Puzzle Help $20''\times 27'' = 540$ sq inches Equally dividing that over 1000 pieces gives us $0.54$ sq inches per piece. Assuming that the pieces are square, we have a borderlength of $\sqrt{0.54}=0.735''$ per piece. The amount of pieces along one border is $27/0.735=36.73$ - This is not even close to an integer, meaning our assumption (pieces are square and equally in size) was incorrect - we need to know that in order to give qualified answers ;) Sep1 comment $\pi$ in arbitrary metric spaces @Arjang aside from that this is the first question ever on Math.SE that has $\pi$ points? I guess not. Aug13 comment Solving Linear ODE using matrices it means that $\begin{pmatrix}\dot x\\\dot y\end{pmatrix}=A\begin{pmatrix}x\\y\end{pmatrix}=\begin{pmatrix}y\\x\end{pmatrix}$ Aug5 comment Mathematical notation for redefined set? Yes. Write $W:=\{1,3,5,2,7,9,10,18\}$ and $W':=\{7,9,10,18\}$ and everyone will know what your intention is. Aug5 comment Mathematical notation for redefined set? This is generally accepted. Use $:=$ for definitions and you have to care about ambiguity. You could even define your own notation, for example $W_{>5}$, however $W'$ is totally fine.
