• Also be able to do the following problem:
   Let A₁ and B₁ be the vectors (1,2,0) and (-3,1,0), respectively. Let A₂ and B₂ be the vectors obtained by rotating A₁ and B₁ by an angle of 60 degrees in the counterclockwise direction about the Z-axis. Compute the vectors A₂ and B₂ and show that the cross product of A₂ with B₂ is the same as the cross product of A₁ with B₁.
  Hint: to compute A₂ and B₂, express the x,y-coordinates of A₁ and B₁ using polar coordinates.
  Answer: A₂=(-1.232, 1.866, 0); B₂=(-2.366, -2.098, 0) and A₁ x B₁ = (0,0,7) = A₂ x B₂.
