Jawaban Soa1
1. a. Perpindahan Vektor secara analitis
b. Panjang Vektor :
R = - 4x + 3y =
Jawaban Soal 2
Diket :
A = 2i + 3j +2k
B = 4i + 2j + k
C = j - 2k
Ditanya :
a. B x A
b. A x C
Jawab:
a. B x A = (4i + 2j + k) x (2i + 3j + 2)
= 0 + 12K + (-8j) + (-4K) + 0 + 4i + 2j + (-3i) + 0
= i - 6j + 8K
b. A x C = (2i + 3j + 2K) x (j - 2K)
= 2k + 4j + 0 + 0 + (-6i) + (-2i) + 0
=-8i + 4j + 2k
b. Panjang Vektor :
R = - 4x + 3y =
