Name : Parallel or Perpendicular?
=========================================================
Description :
Given two force vectors, find out whether they are parallel, perpendicular or neither. Let the first vector be A = a1 i +a2 j + a3 k and the second vector be B = b1 i + b2 j + b3 k.
A.B = a1 * b1 + a2 * b2 + a3 * b3
A x B = (a2 * b3 - a3 * b2) i - (a1 * b3 - b1* a3) j + (a1 * b2 - a2 * b1) k
|A|2 = a12 + a22 + a32
If A.B = 0, then A and B are perpendicular.
If |A X B|2 = 0, then A and B are parallel.
