Mathematics for IGCSE & O level - Vectors (Section 5 - No. 48)
Which of the following statements are true regarding vector geometry?
Vectors can be added in any order.
Multiplying a vector by a scalar changes its direction but not its length.
If AB = CD, then AB and CD are parallel and the same length.
The magnitude of the vector AB is written as |AB|
解释
Vectors can be added in any order. If AB = CD, then AB and CD are parallel and the same length. The magnitude is correctly written. Multiplying changes the length and not the direction.
