webThey can be multiplied using the "Dot Product" (also see Cross Product). Calculating. The Dot Product is written using a central dot: a · b This means the Dot Product of a and b. We can calculate the Dot Product of two vectors this way: a · b = |a| × |b| × cos(θ) Where: |a| is the magnitude (length) of vector a |b| is the magnitude (length ...
