Di berikan : a = 3i+2j-3k b =-2i-j+2k Hasil kali silang (cross product) vektor diatas adalah

Diket :
Dua vektor a dan b,
a = (3)i + (2)j + (- 3)k
b = (- 2)i + (- 1)j + (2)k

Tanya :
Product cross, a x b = __?

Jawab :
a x b = (2•2 - (-1)•(-3))i - (3•2 - (-2).(-3)j + (3•(-1) - (-2).(2))k
a x b = (4 - 3)i - (6 - 6)j + (- 3 + 4)k
a x b = (1)i - (0)j + (1)k

a x b = i + k
