He is learning things that will never see use for games he will never finish
Yeah idk
I assume he means cofactor expansions?
Unless he just means 3x3's which you can solve trivially

Damn maybe its time to unprivate
That is apart of the cofactor expansion, yes
This is a consequence of the fact that swapping any two rows or columns in a determinant swaps the sign
If you want a more concreate explanation, there are geometric interpretations of the determenant I do not know because I do not do geometric algebra
Determanat represents the physical properties of how a matrix is a mapping that transforms an input into an output
so the sign change is kind of a symmetry thing
You get some geometric stuff in 3D
such as the absolute value of the det being the volume of a parallelpiped
I don't really care about the geometric interpretations of determinant tbh
If you just abstractly view it as an operation with properties (which is what I do) then it is perfectly fine
I don't in particular do much determinant stuff other than when doing TA work for lin alg courses, but I am used to it because of how important it is in physics
like there is no guarantee that an arbitrary sampling on a 2-sphere (and other manifolds in additionally higher dimensions) can have an invertible map to a harmonic decomposition, because smoothly swapping two points on the manifold flips the sign of the map's determinant, and at some point in the swap the determinant has to go to 0

This is the most pretentious trailer I think I've ever seen
sorry for insulting P6 last week
the yogscast are revealing new games that will show up in the jingle jam collection in a couple years

I have awoo'd at the moon in your pic
may it bring you continued luck
