Question

A line passes through the points A(0,3, 2) and B(4,-1,6),
then direction ratios of AB are?​

Answer 1

Step-by-step explanation:

Consider the problem

Let l,m,n are direction cosines of the given line.

then as it made an acute angle with x−axis,

Therefore, l>0

The line passes through (6,−7,−1) and (2,−3,1)

Therefore, its direction ratios are

6−2,−7+3,−1−1 or 2,−2,−1

Hence direction cosines of the line are given by
