Chapter 11.2, Problem 1DE

For the vectors $\stackrel{\to }{A}$ and $\stackrel{\to }{B}$ in the plane of the page as shown in Fig. 11–9, in what direction is (i) $\stackrel{\to }{A}\cdot \stackrel{\to }{B}$, (ii) $\stackrel{\to }{A}\times \stackrel{\to }{B}$, (iii) $\stackrel{\to }{B}\times \stackrel{\to }{A}$ ? (a) Into the page; (b) out of the page; (c) between $\stackrel{\to }{A}$ and $\stackrel{\to }{B}$; (d) it is a scalar and has no direction; (e) it is zero and has no direction.

D: (i) (d); (ii) (a); (iii) (b).
