WebThis tells us the dot product has to do with direction. Specifically, when \theta = 0 θ = 0, the two vectors point in exactly the same direction. Not accounting for vector magnitudes, this is when the dot product is at its largest, because \cos (0) = 1 cos(0) = 1. In general, the more two vectors point in the same direction, the bigger the dot ... WebDefining the scalar product of 2nd ranked tensors as. The double dot product is an important concept of mathematical algebra. It is a way of multiplying the vector values. Before learning a double dot product we must understand what is a dot product.
