  • Almost:

    Lengths are usually reals, and in this case the diagram suggests we can assume that A is the origin wlog (and the sides are badly drawn vectors without a direction)

    Next we convert the vectors into lengths using the abs function (root of conjugate multiplication). This gives us lengths of 1 for both.

    Finally, we can just use a Euclidean metric to get our other length √2.

    Squaring isn’t multiplication by complex conjugate, that’s just mapping a vector to a scalar (the complex | x | function).















  • Really neat post, I’d not heard of a few of these (never knew libre office draw could edit pdfs!).

    Couple of extra ones:

    Note taking and pdf annotation: Xournal++ is amazing, it’s also great to use on larger whiteboard screens. Plug and play support for scribe tablets on both windows and Linux.

    Emulation (up to ps1): Mednafen is lightweight and comes with a gui. It also supports recording, though not netplay.

    Ebook management/reading: Calibre - allows easy importing and exporting of ebooks to devices, also has a great built in search letting you find DRM free versions of a book.

    Heh, I did this once - mostly because 10+ PowerPoint animations really chug the university issue laptops, and I was presenting somewhere new (software is not your friend).

    It was really 15 slides with about 20 animation steps on each - the students didn’t seem to hate seeing a set of fully worked maths problems with colour coding linking parts of the question to the resultant equation.
