Question
Find the distance between the lines l1, and l2 given by
and 
Solution
The equations of two lines are
...(1)
and
...(2)
Line (1) passes through the point S with position vector
and line (2) passes through the point T with position vector 
Also both lines are parallel to the vector 
Now,
Let d be the distance between the lines
...(1)and
...(2)Line (1) passes through the point S with position vector
and line (2) passes through the point T with position vector Also both lines are parallel to the vector Now,
Let d be the distance between the lines
