The Dot Product
- Mathematical quantities come in two kinds:
- scalars, which have magnitude only (but no direction)
- vectors, which have magnitude and direction
- The dot product of two vectors is a scalar.
It is largest if the two vectors are parallel,
and zero if the two vectors are perpendicular.
