Ex1:- Given the two points P(1,2,3) and Q(2,-2,1) find the vectors
FP,FQ from the origin. Then estimate the vector RPQ.
Solution :-
dal al
P(1, 2, 3)
To
Q(2,- 2, 1)
(c)
rP = (1-0)āx + (2 - 0)āy + (3- 0)āz
Then FP = āx + 2āy + 3āz
Can you find a
|FP| = J(1)2 + (2)2 + (3)2
summary of the
|FP| = V14
technical laws to
solve this example??
FQ = 2āx – 2āy + āz
|FQ| = V(2)2 + (-2)² + (1)²

|FQ| = V4 + 4 + 1 = 3
RPQ = FQ – FP = (2 - 1)āx + (-2 – 2)āy + (1 - 3)āz
Then RPQ = āx – 4āy – 2āz = -RQP
|RQP| = V1+ 16 + 4 = v21
RPQ = Ax āx + Ayāy + Azāz
Ax=1,Ay = -4, Az = -2 (component of the vector)
Unit vector of RPQ is :-
RPQ
=
= direction of the vector RPQ
|RPQ|
