perkalian cross (X) merupakan perkalian vektor, sehingga hasilnya berupa vektor
i X i = j X j = k X k = 0
i X j = k; j X k = i; k X i = j
maka jika dibalik j X i = -k; k X j = -i; k X i = -j
Vektor A = 2i + 6j
Vektor B = 3i
maka A X B = (2i + 6j) X 3i
A X B = 0 + 6.3(-k)
A X B = -18k
semoga dapat membantu ...
