VI Info - Figure 5 shows approximately the same vector diagram as in Question 3. However, the left-to-right vector at the bottom of the triangle is labeled u and the right-to-left vector is labeled v. Vector v has its tail at the head of vector u. Both of those vectors are black and each has its tail and its head labeled as "tail" and "head".
A third blue vector labeled u+v extends from the tail of vector u to the head of vector v with its head at the head of vector v.
