coordinates of a vector from the coordinates of two points
Let(O,`vec(i)`,`vec(j)`) be a reference frame of the plane. Let D and F be two points of coordinates `(15,2)` and `(4,2)` respectively in this frame, compute the coordinates of the vector `vec(DF)`.
This type of exercise can be solved using the function : vector_coordinates
