If the position vectors of the points A (3, 4), B (5, -6) and C (4, -1) are respectively, compute

Question

Philoid · Accepted Answer

Given A = (3, 4), B = (5, –6) and C = (4, –1)

We know position vector of a point (x, y) is given by, where and are unit vectors in X and Y directions.

(position vector of point A)

We also have

Similarly.

We need to compute.

Thus, .
