− | Multiplying a vector <math>\vec{\mathbf{a}}</math> by a real value ''p'' results in a vector <math>\vec{\mathbf{a}} | + | Multiplying a vector <math>\vec{\mathbf{a}}</math> by a real value ''p'' results in a vector <math>\vec{\mathbf{a}}_p</math> with { same direction } and different magnitude. The magnitude changes with { factor } <math>{p}</math>. If the resulting vector <math>\vec{\mathbf{a}}_p</math> has an oppsite direction, ''p'' is a { negative value }. The special case ''p=0'' results in a { zero vector }. |
