Webi. u × v = − (v × u) Anticommutative property ii. u × (v + w) = u × v + u × w Distributive property iii. c (u × v) = (c u) × v = u × (c v) Multiplication by a constant iv. u × 0 = 0 × u = 0 Cross … Web0 −(v2w3 −v3w2) v1w2 −v2w1 v2w3 −v3w2 0 −(v3w1 −v1w3) v2w1 −v1w2 −v1w3 −w1v3 0 . This is what one calls a Lie algebra. This can be generalized to n×n matrices. While for n = 2 we got the cross product in two dimensions and for n = 3 the cross product in 3 dimensions, we get for n = 4 a cross product in six dimensions.

Pythagoras' theorem: ‖ u + v ‖ 2 = ‖ u ‖ 2 + ‖ v ‖ 2 if u and v are orthogonal AKA u ⋅ v = 0. My trouble is converting ‖ u + v ‖ to ‖ u − v ‖, could be something I am overthinking. This is for a first year university course. Thanks.
