Let $ f\in\mathbb{Q}[x]$ a monic polynomial such that $ f$ has degree $ n$ . Let $ E_f$ be the splitting field of $ f$ over $ \mathbb{Q}$ . I would like to show that there exists a monic polynomial in $ \mathbb{Z}[x]$ such that it has the same splitting field. I don’t even knowRead more
I am a first reader of Differential Equation. I was solving a differential equation whose solution is $ |f(x)|= c$ . Now my question is can I write that the solution is $ f(x)= k$ . If $ f(x)$ is continuous then I can remove the mod. But I am not sure whether the functionRead more

If I set up a = 1 Is there any command to get “a” by typing value 1? Another example. If x = 3 y = 7 z = 6 then, Can I get ‘xyz’ by typing something like {3,7,6}?Read more
Let $ A$ be a $ n\times n$ real matrix. Is there a vector $ \vec x \in \mathbb{R}^n$ with exactly $ 0 \le k < n$ zero entries such that $ A \vec x = 0$ ? Is there an efficient algorithm to tackle this question?Read more
I want to plot a 2D disk in 3D space, angled perpendicular to a given direction. That direction is given by $ \theta$ and $ \phi$ in spherical coordinates (where $ \theta$ is polar and $ \phi$ is azimuthal cause I’m a physicist, sorry math people!). [I apologize for the upcoming bad code formatting, I’veRead more
I am looking to have an android wearable (preferable a Smartwatch) with the following specifications: 1) Standalone (must have its own SIM card and should work without a phone connected to it) 2) Net Connectivity. This also means that it is possible to extract the wearable’s location using the net (as we can do withRead more
Scenario: Let us consider oracle 3 node RAC. RMAN Auto Recovery is used between production and standby DBs. Let us assume that the SCNs of 3 nodes are S1, S2, S3 at some point of time respectively. Let Smax=max(S1,S2,S3) Is there any possibilities to get the archive file name containing the given SCN, Smax inRead more
