A way of multiplying two vectors:

Where || means "the magnitude (length) of"

And θ is the angle between the vectors

Example: the lengths of two vectors are 3 and 4, and the angle between them is 60°

So the dot product is:

**a · b**= |**a**| × |**b**| × cos(θ)Where || means "the magnitude (length) of"

And θ is the angle between the vectors

Example: the lengths of two vectors are 3 and 4, and the angle between them is 60°

So the dot product is:

**a · b**= 3 × 4 × cos(60°) = 3 × 4 × 0.5 = 6See: Cross Product
