I'm having trouble trying to solve a problem I was given for my homework in Vector Calculus, and I was wondering if someone could help me out. Here is the problem in question:
- Draw two vectors as arrows in the plane of the paper with their tails together. Label them u and v. Draw a third arrow extending between the head of u and the head of v. This arrow will either represent the vector u - v or v - u. Explain how you can decide which of these it is (u - v or v - u).
I have the drawing set up on my paper, but I don't really know where to go from there. If you don't know the direction of the third arrow that you have to draw between u and v, how do you solve this to determine whether this final arrow represents 'u - v' or 'v - u'? Any help on this problem would be greatly appreciated.
