1. ### "Bloody", a discouraged word to use in Britain

"Bloody" can be used as a (mild) expletive and it is not nice to utter expletives. Usage other than as an expletive is perfectly acceptable. I don't agree with that: "a bloody weapon" conveys something different to a "blood-stained weapon" and there is no alternative to e.g. a "bloody battle".
2. ### B What kind of definition is this?

We are talking about points that exist at the end of a bounded interval, ## \pm \infty ## would be troublesome here. Yes Yes Yes. ## 0 ## is also a singular point.
3. ### Which one is better -- WSL2 or USB booted Ubuntu?

Yes that's a good point, although its a bit more complicated Fedora releases are effectively only supported for 13 months from release. So the Fedora 34 that you installed last week which was released in April is already 6 months into its cycle: assuming Fedora 36 is released on schedule...
4. ### Which one is better -- WSL2 or USB booted Ubuntu?

Quick translation: https://fedoraproject.org/wiki/Differences_to_Ubuntu#Package_Management (Edit: and for the pedant, note that apt does mostly work in current Fedora, there is just no point in installing it)
5. ### Which one is better -- WSL2 or USB booted Ubuntu?

Really? Are you using the Gnome desktop that comes in the standard distro? I just can't get on with any desktop that thinks it is a good idea to put the main menu for an application in a different place to the application window - or maybe you are using a different spin. Anyway, if you like...
6. ### B What kind of definition is this?

Yes but that is not the same as saying the 'idea' of an open interval is complementary to the 'idea' of a closed interval, and I have edited my post to provide examples which explain why.
7. ### B What kind of definition is this?

(Edited) No, the complement of an open interval is not necessarily even an interval. Also consider the intervals ## [0, 1) ## which is neither closed nor open and ##(- \infty, + \infty)## which is both closed and open. The definitions are clear (from MathWorld). An open interval is an...
8. ### Which one is better -- WSL2 or USB booted Ubuntu?

That's a great strategy. Coming from Windows and particularly with a lower spec machine I recommend you try Linux Mint Xfce Edition.
9. ### Inserting a subscript in the text in the following diagrams app.

Oh I see! Select Extras -> Mathematical typesetting and then you can use ## \LaTeX ## e.g. $$f_{2,G_2}$$ https://www.diagrams.net/doc/faq/math-typesetting
10. ### Inserting a subscript in the text in the following diagrams app.

Works for me using the x2 button highlighted below
11. ### Foundational Mathematics

In that case how is it possible to answer your original questions?
12. ### Foundational Mathematics

Not sure where you are from but in the US each state has its own high school curriculum standards, this is also true for each constituent country (England, Scotland, Wales and Northern Ireland) of the UK (I don't know about any other countries). So there is no generally relevant answer to your...
13. ### How to install FORM (for high-energy physics) on Windows?

Still too many abbreviations. I believe the OP is asking about this: https://github.com/vermaseren/form. There does not appear to be a release for Windows, you could build it yourself using e.g. the gcc compiler under cygwin but it would be much easier to run it under the Windows Subsystem for...
14. ### Programming language: what to study after the basics?

This is probably not the place for a comparative debate on software development paradigms but you should be aware that one motivation behind the Agile Manifesto (which I find hard to believe is now 20 years old) was that many projects had suffered from an over-emphasis on a design document...
15. ### A Array variable of envelope function (parameter representation)

Oh I think I see where the confusion lies, let me check. You are talking about the envelope of a family of curves. We don't call this an 'envelope function' because the envolope is often not a function. I think you are confused by the reference to a 'parameter' in relation to the family of...
