Addition and Multiplication of Vectors

Associative property:

[1] Multiplication of Vector by a Scalar

[2] Components of Vector

[3] Vector joining two points

 Let P1(x1, y1, z1) and P2(x2, y2 z2) be the two points. Then vector joining the

points P1 and P2 is P1P2 . Join P1, P2 with O. Now OP₂ = OP₁ + P1P2   (by triangle law)
