Show that the lines
and
do not intersect.
Given equations :
To Find : d
Formula :
1. Cross Product :
If are two vectors
then,
2. Dot Product :
If are two vectors
then,
3. Shortest distance between two lines :
The shortest distance between the skew lines and
is given by,
Answer :
For given lines,
Here,
Therefore,
Now,
= - 68 + 256 + 0
= 188
Therefore, the shortest distance between the given lines is
As d ≠ 0
Hence, the given lines do not intersect.
