Example Question #81 : Vectors & Spaces

Given points  and , what is the vector form of the distance between the points?

Possible Answers:

Correct answer:

Explanation:

In order to derive the vector form of the distance between two points, we must find the difference between the , , and elements of the points. That is, for any point and , the distance is the vector .

Subbing in our original points  and ,  we get:
