What is the condition for 2 vectors to be collinear? |
| Answer» Two vectors are collinear, if any of these conditions done:Condition of vectors collinearity 1. Two vectors a and b are collinear if there exists a number n such thata = n · bCondition of vectors collinearity 2. Two vectors are collinear if relations of their coordinates are equal.N.B. Condition 2 is not valid if one of the components of the vector is zero.Condition of vectors collinearity 3. Two vectors are collinear if their cross product is equal to the zero vector.N.B. Condition 3 applies only to three-dimensional (spatial) problems. | |
