Vector dot product 3d. Given the geometric definition of the dot product along with the dot product formula in terms of components, we are ready to calculate the dot product of any pair of two- or three-dimensional vectors. Example 1. Calculate the dot product of $\vc{a}=(1,2,3)$ and $\vc{b}=(4,-5,6)$. Do the vectors form an acute angle, right angle, or obtuse angle?
So you would want your product to satisfy that the multiplication of two vectors gives a new vector. However, the dot product of two vectors gives a scalar (a number) and not a vector. But you do have the cross product. The cross product of two (3 dimensional) vectors is indeed a new vector. So you actually have a product.
