Let's imagine we have two vectors $\vc{a}$ and $\vc{b}$, and we want to calculate how much of $\vc{a}$ is pointing in the same direction as the vector $\vc{b}$.The dot product of two unit vectors behaves just oppositely: it is zero when the unit vectors are perpendicular and 1 if the unit vectors are parallel. Unit vectors enable two convenient identities: the dot product of two unit vectors yields the cosine (which may be positive or negative) of the angle between the two unit vectors.
