| This works. Thanks Gianluca. (I think I tried this before. No idea why I thought it would not work). |
| Thank you for the honor. You have heavily edited my post. Is it a good idea to copy my entire notebook into the post? I only had a short introduction and then added my notebook. |
| No idea how to achieve that within Wolfram. Probably there are general Windows Tools for keyboard/mouse recording. But I doubt that these will really help you. |
| Thanks Ian. Is there a list of known bugs somewhere? |
| Thanks, Michael, that's a good example of building custom controls. Of course, I can always build my own custom controls if I want, and I do sometimes. But my goal is not to improve the Wolfram system, but to solve my own problems using the Wolfram... |
| Thank you, David, I understand. And how do I then install the MakeProject and MakeContents palettes in the “Palettes” menu? |
| As I said: In general the function domain is not a simple interval or one-dimensional Cuboid. But the result of some logical expression which could be arbitrarily complicated. As another example: c = 2/10; f1[x_] := 20 (x - 4/10)^3; ... |
| Assuming I understood what you meant, I wrote a solution notebook in Wolfram Language. I don't think you can solve it in WolframAlpha (maybe with the desktop version, which I don't have). &[Wolfram Notebook][1] [1]:... |

| The reason for the message *NDSolve::pdord* is that you do not specify differential equations for Nf[t] and fs[t]. So we are only dealing with arbitrary predefined functions Nf[t] and fs[t] with given values and derivatives at t = 0. How is this... |
