Possible Error in "distance between planes " video on linear algebra.
Beantwoord
At 6:27 sal is calculating a cross product of two vectors in 3d space. He calculates i as (a2×b3)-(a3×b2) which is fine. What I'm confused about is why he calculates j as (a1×b3)-(a3×b1) instead of (a3×b1)-(a1×b3) ? I specifically remember him saying that calculating j goes against your normal intuition to cross multiply the same way you would for i and k.
I would post this on the video but I don't have enough points to comment and need an answer quickly.
