Chapter 11, Problem 29P

(II) Use the result of Problem 26 to determine (a) the vector product $\stackrel{\to }{A}\times \stackrel{\to }{B}$ and (b) the angle between $\stackrel{\to }{A}$ and $\stackrel{\to }{B}$ if $\stackrel{\to }{A}=5.4\hat{i}-3.5\hat{j}$ and $\stackrel{\to }{B}=-8.5\hat{i}+5.6\hat{j}+2.0\hat{k}$.
