Find the direction ratios and the direction cosines of the vector joining the points A(2, 1, -2) and B(3, 5, -4).

Question

Philoid · Accepted Answer

A = (2,1,-2)

B = (3,5,-4)

Tip – For any vector the direction ratios are represented as (a_x , a_y ,a_z) and the direction cosines are given by

The direction ratios are (1,4, -2)

The direction cosines are
