Chapter 7.3, Problem 7.3QQ

Which of the following statements is true about the relationship between the dot product of two vectors and the product of the magnitudes of the vectors? (a) $\stackrel{\to }{A}\cdot \stackrel{\to }{B}$ is larger than AB. (b) $\stackrel{\to }{A}\cdot \stackrel{\to }{B}$ is smaller than AB. (c) $\stackrel{\to }{A}\cdot \stackrel{\to }{B}$ could be larger or smaller than AB, depending on the angle between the vectors. (d) $\stackrel{\to }{A}\cdot \stackrel{\to }{B}$ could be equal to AB.
