1. The problem statement, all variables and given/known data Let A be an arbitrary vector and e be a unit vector in some fixed direction.Show that A=e(A.e)+e x (A x e) What is the geometrical significance of each of the two terms? 2. Relevant equations 3. The attempt at a solution I can show it easily.As the first term (a dot product) is the component in the e direction and the 2nd term(a cross product) is the component in the perpendicular direction. What else geometrical significance they may be talking about?
