"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 ... " - Gradient dotted with a vector
