I have a question about JoinAcross. In this case the left association is returned unchanged: JoinAcross[{ 1, b -> X|>}, { 2|>}, Key[a], "Left"] (* { 1, b -> X|>} *) The result is expected. Notice that the "Left" is documented as...
You may find this demonstration useful: [Mechanical Involute Gears][1]. [1]: https://demonstrations.wolfram.com/MechanicalInvoluteGears/
Try adding the SaveDefinitions->True option to the Manipulate. BTW, please don't put you code in hidden cells when asking here.
Maybe you could use Sow[] to collect the un-formatted results inside the While and then use Reap[] to get the collected values.
Javier, please always include the source code in order to be able to understand what the issue is. I tried with this and it seems to work: Solve[ {(o - x) (n - x - y - z) == (a - x - y) (b - x - z), (p - y) (n - x - y - z) ==...
Your notebook contains a Manipulate. As long as you don't use any InputField (or other advanced features), they should be able to use it with the free [Wolfram Player][1]. This used to be called FreeCDF. To do the same without those restrictions...
This is one way to create new window with a plot centered: CreateDocument[{ExpressionCell[ Plot3D[Sin[x y], {x, -1, 1}, {y, -1, 1}, ImageSize -> Full]]}, WindowSize -> Full]
I would not recommend that. The book is about 50% images.
The 1st line should be: getBooks[bookURL_String] := just a copy/paste error.
Have you tried setting the [AutoGeneratedPackage][1] notebook option to Automatic? This way you would auto-generate a "file test.m" file with the initialization code and without the Cell stuff. [1]:...
