Problem 4: It should be obvious that the magnitude of a vector is independent of the
choice of coordinate system. This implies that r r is the same for any set of axes. Use this
to prove that the dot product of two different vectors r.s is also independent of coordinate
system. [Hint: Consider the length of r + s.]
