Ada dua vektor ,masing masing A= -3i+4j, dan vektor B= 2i+3j ,tentukan lah AxB
![]()
A = -3i + 4j
Kalo dalam bentuk matriks:
[tex]\left[\begin{array}{ccc}-3\\4\\\end{array}\right][/tex]
B = 2i+3j
Kalo dalam bentuk matriks:
[tex]\left[\begin{array}{ccc}2\\3\\\end{array}\right][/tex]
Jika dikaliin AxB:
AxB
= [tex]\left[\begin{array}{ccc}-3\\4\\\end{array}\right][/tex] x [tex]\left[\begin{array}{ccc}2\\3\\\end{array}\right][/tex]
= [tex]\left[\begin{array}{ccc}-6\\12\\\end{array}\right][/tex]
= -6 + 12
AxB = 6
