Vector Geometry Operations edit
Addition and Subtraction edit
If and are vectors,
Then the sum
- is also a vector (see Figure 2(a)).
The two vectors can also be subtracted from one another to give another vector
Multiplication by a scalar edit
Multiplication of a vector by a scalar has the effect of stretching or shrinking the vector (see Figure 2(b)).
You can form a unit vector that is parallel to by dividing by the length of the vector . Thus,
