Let P and Q be points with corresponding vectors p and q.
a) show that the vector 1/2p+1/2q is the midpoint of the line segment joining P and Q
b)Find a point that is one third of the distance from P to Q
The Attempt at a Solution
I'm not really sure.. but if you were to consider P to be one unit vector and Q to be one unit vector then PQ would be 2 unit vectors??
