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.
