@Satsuma i lied

@Satsuma yeah not gonna happen lol

@vaporeon_ in the end, though, you don't have to prove these if you want to know where a rotation matrix comes from. vaporeons are allowed to take the formulae for granted

Anyway @vaporeon_ this is where the rotation matrix comes from

@vaporeon_

@Satsuma it was supposed to be a joke

I started playing fire emblem at like, 6pm yesterday and then I looked at the clock and it was 3am

Hi @vaporeon_ I forgot to ask last night if you were familiar with the formulas

sin(x + y) = sin(x)cos(y) + cos(x)sin(y)
cos(x + y) = cos(x)cos(y) - sin(x)sin(y)
?

@amy hi crossword woman

@vaporeon_ you will see when I share the textbook excerpt tomorrow :)

@vaporeon_ I will give you the math tomorrow

@vaporeon_ I took picture of the floor and drew math on that picture, it was fast as there were no pens and paper in my vicinity

@vaporeon_ yes this is right

@vaporeon_ what are the lengths of x and y in terms of Φ?

@vaporeon_ doing physics made me better at math but that's not a simple road haha

I'm not sure where a good place to start is. Maybe read MIT's free lecture notes on discrete mathematics and do the homework assignments?

@vaporeon_ if you're truly curious I could share a picture from my undergraduate e&m textbook which goes over this in the first chapter

Also how familiar are you with sin and cos?

@vaporeon_ a high level knowledge of mathematics isn't necessary to program but it does make you better

@vaporeon_ hi vappy

@Lucy can you buy me some ground cinnamon i just ran out
