Perpendicular distance from a point to a line (Vector)
- What is the shortest distance between a point which located at (1,2,-3) to the line of r = 2i +5j +10k + lambda (3i +6j + 5k).
cos x = a.b/(|a||b|)
a.b is the scalar product of two vector
If a is perpendicular to b, then cos x = 0.
In addition, this means a.b = 0.
