Sean A=(2, 4 ,6) y B=(-1, 3, -2), calcular:
A.B
= (-2 +12 -12)= -2
AXB
(2i, 4j, 6k) X (-1i, 3j, -2k)
-2i + 6ij - 4ik – 4ji +12j -8jk -6ki +18kj -12k
= 6k + 4j + 4k -8i -6j -18i
= -26i -2j +10k
B.A
= (-2 +12 -12)= -2
BXA
(-1i, 3j, -2k) X (2i, 4j, 6k)
-2i -4ij -6ik +6ji +12j +18jk -4ki -8kj -12k
= -4k +6j -6k +18i -4j +8i
= 26i +2j -10k
