WitrynaWeighted Euclidean Inner Product The norm and distance depend on the inner product used. If the inner product is changed, then the norms and distances between vectors also change. For example, for the vectors u = (1,0) and v = (0,1) in R2 with the Euclidean inner product, we have 2008/12/17 Elementary Linear Algebra 12 However, if we … WitrynaThis 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 ...
