If the angle between them is cos (180), i.e., both the vectors are connected by one of their ends, pointing in opposite directions, then the value will indeed be 1, but with a negative sign before it. And so, the negative existence of dot product can be justified. Dot Product Formula

WebDot product can be negative, since we are not taking absolute value when we add products of coordinates from the vector inputs. For example, recall the example from earlier: the dot product of a•b = [1, -2, 8]• [4, 5, -3] is -30. Can Dot Product Be Greater Than 1? Dot product can be greater than 1, since the vectors can have any length.
WebAnswer (1 of 2): Yep. The most general way to describe a word vector (a.k.a. embedding) is the following. It is an N-dimensional vector (a vector in \mathbb{R}^N) that describes a word. Two vectors in \mathbb{R}^N can definitely have a negative dot product. For example,[+1, +1, \dots, +1] and [-... WebMay 8, 2016 · So when three vectors point more or less to the vertices of an equilateral triangle all three dot products will be negative. Let v 1 = ( x 1, y 1) , v 2 = ( x 2, y 2) and v 3 = ( x 3, y 3). Which is a 3 × 3 system of inequalities that …
WebAnswer (1 of 3): If the angle between two vectors is acute, then their scalar product (also called dot product and inner product) is positive. If the angle between two vectors is right, then their scalar product is zero. If the angle between two vectors is obtuse, then their scalar product is n...
