WebOne is called the dot product. It returns a scalar with a magnitude equivalent to the area of the parallagram between the two vectors. In practical terms the dot product of normalised vectors is equal to the cosine of the angle between them. This can produce really quick angle checks on normalised vectors. The other is called the cross product. WebIf you have two real numbers x and y ≠ 0, we say that x y = z exactly when x = yz. So in that sense you could define a type of division of vectors. However, again there are some problems with vectors. When we divide by a real number y, we can also consider this as multiplying by the inverse of y, that is, y − 1.
