hi, i don't really understand whats the difference between vector product and dot product in matrix form.(adsbygoogle = window.adsbygoogle || []).push({});

for example

(1 2) X (1 2)

(3 4) (3 4) = ?

so when i take rows multiply by columns, to get a 2x2 matrix, i am doing vector product?

so what then is dot producT?

lastly, my notes says |detT| = final area of basic box/ initial area of basic box

where detT = (Ti) x (Tj) . (Tk)

so, whats the difference between how i should work out x VS . ?

also, |detT| = magnitude of T right? so is there a formula i should use to find magnitude?

so why is |k . k| = 1?

thanks
