On my own User Portal (user.wolfram.com), on the "My Products and Services" page, Mathematica item, Downloads section, I see both "Mathematica Download Manager" and "Mathematica Direct Download (optional)". If you see that, too, then use the...
You are not likely to receive much help unless you include *copyable* code instead of a graphic image of code. You may use the first icon, at the left-hand end of the editor here, to markup code.
How easy one coding style or the other is to debug depends on the background of the coder doing the debugging! If a programmer has spent years writing and debugging procedural coding but only a relatively short time writing functional code, then it...
Two comments and a question arising from the visualizations of the unit *p*-sphere in the plane.... *Comment 1*: Curiously, the built-in function `Norm` in its two argument form `Norm[vec, p]` prohibits values of `p` that are less than 1. Of...

If I understand what you're trying to accomplish, which is to create a square zero-matrix, then the following does what you want: n = Input[]; mat = ConstantArray[0, {n, n}]; Det[mat] (* 0 *) There's no...
As I reported, `OpenSQLConnection` is working for me when `fmjdbc.jar` is in `/Library/Java/Extensions` and yet is *not* in `/Applications/Mathematica.app/Contents/SystemFiles/Java/`.
You could try, instead: Tally[Head /@ ToExpression /@ Names["System`*"]] With Mathematica 12.0, the result I get is: {{Symbol, 6331}, {GrayLevel, 5}, {RGBColor, 20}, {DirectedInfinity, 4}, {Dashing, 3}, {GeoPosition, 2},...
On a localhost installation of webMathematica (with Mathematica 12.0 as engine) under macOS Mojave 10.14.4, and using tomcat 9.0.1, I can run the supplied examples *except* those that create 3D graphics, e.g., "Live 3D Plotting" and "Polyedron...
