Given this, is there a faster way to compute this or must I do 3 separate 3x3 determinants?
I can probably use cross product of each term, for example , (2rk) X (Axi) = (-2rAx j) (not forgetting the negative sign for j)
next, (2rk) X (Ayj) = (2rAyi)
and so on... but that feels too slow as well and can get very messy.
