When constructing the vector equation for the position vector r (finishing at point P) in the drawing below. Why is it necessary to use a "direction vector", v ? Couldn't one just use vector a and have done with it??
Why do we need to define this new vector r??What is the point.
I would appreciate it if you guys could reply in simple laymans english.
I thank you in advance.
