This gives me a value between $1$ and $-1$. $1$ means they're parallel to each other, facing same direction (aka the angle between them is $0^\circ$). $-1$ means they're parallel and facing opposite directions ($180^\circ$).Parallel Vectors The total of the products of the matching entries of the 2 sequences of numbers is the dot product. It is the sum of the Euclidean orders of magnitude of the two vectors as well as the cosine of the angle between them from a geometric standpoint. When utilising Cartesian coordinates, these equations are equal. Since the dot product is 0, we know the two vectors are orthogonal.

May 8, 2017 · Dot products are very geometric objects. They actually encode relative information about vectors, specifically they tell us "how much" one vector is in the direction of another. Particularly, the dot product can tell us if two vectors are (anti)parallel or if they are perpendicular.

Geometrically, the scalar triple product. is the (signed) volume of the parallelepiped defined by the three vectors given. Here, the parentheses may be omitted without causing ambiguity, since the dot product cannot be evaluated first. If it were, it would leave the cross product of a scalar and a vector, which is not defined.The dot product of two parallel vectors is equal to the algebraic multiplication of the magnitudes of both vectors.
