Tntang vektor, pliiss bantuin kk, hri ni dkumpul ^^

a = (-3, 4)
vektor satuan a = a / |a|
= (-3, 4) / (√(-3)² + (4)² )
= (-3, 4) / (√9 + 16)
= (-3, 4) / (√25
= (-3, 4) / 5
= (-3/5, 4/5)

b = (2, -1, 2)
Vektor satuan b = b / |b |
= (2, -1, 2) / √(2)² + (-1)² + (2)²
= (2, -1, 2) / √9
= (2/3, -1/3, 2/3)
