Question 289125
Hint: Recall that the angle between two vectors *[Tex \LARGE \vec{a}] and *[Tex \LARGE \vec{b}], let's call it *[Tex \LARGE \theta], can be represented in the equation:


*[Tex \LARGE \cos(\theta) = \frac{\vec{a}\cdot\vec{b}}{\|\vec{a}\|\|\vec{b}\|}] where *[Tex \LARGE \|\vec{a}\|] is the magnitude of *[Tex \LARGE \vec{a}] and *[Tex \LARGE \|\vec{b}\|] is the magnitude of *[Tex \LARGE \vec{b}].
