kurang 1 no ajaaa pleaseeee
kalo ga bisa gausah jawab

Jawab:
a = 2i - 4j - 2k
b = i + 3j + 2k
proyeksi vektor ortogonal a pada b = c
[tex]\sf \overline c = \dfrac{a.b}{|b|^2}\ . \overline b[/tex]
a.b = 2(1) - 4(3) - 2(2)
a.b = 2 - 12 - 4
a.b = - 14
|b|² = 1² +3² + 2² = 1 + 9 + 4
|b|² = 14
proyeksi vektor ortogonal a pada b =
[tex]\sf \overline c = \dfrac{a.b}{|b|^2}\ . \overline b[/tex]
[tex]\sf \overline c = \dfrac{-14}{14}\ (i + 3j + 2k)[/tex]
[tex]\sf \overline c = \ -1 (i + 3j + 2k)[/tex]
[tex]\sf \overline c = -i - 3j - 2k[/tex]
