VEKTOR
• komponen
• vektor satuan


a][ A = 10 m, α = 45°

komponen x
Ax = A cos α
Ax = 10 cos 45°
Ax = 10 • ½√2
Ax = 5√2 m ✔️

komponen y
Ay = A sin α
Ay = 10 sin 45°
Ay = 10 • ½√2
Ay = 5√2 m ✔️

A = Ax i + Ay j
A = (5√2 i + 5√2 j) m ✔️


b][ B = 20 m, β = 53°

komponen x
Bx = B cos β
Bx = 20 cos 53°
Bx = 20 • 0,6
Bx = 12 m ✔️

komponen y
By = B sin β
By = 20 sin 53°
By = 20 • 0,8
By = 16 m ✔️

B = Bx i + By j
B = (12 i + 16 j) m ✔️
