# Is the dot product associative?

## Is the dot product associative?

In mathematical terms, the dot product is the scalar result of the combination of two coordinate vectors. The dot product is commutative ( ) and distributive ( ), but not associative because, by definition, is actually a scalar dotted with c, which has no definition.

## Is vector product commutative?

Commutative property Unlike the scalar product, cross product of two vectors is not commutative in nature.

Does dot product follow associative law?

In dot product, the order of the two vectors does not change the result. The associative law of multiplication also applies to the dot product.

### Does dot product obey commutative law?

Scalar multiplication of two vectors (to give the so-called dot product) is commutative (i.e., a·b = b·a), but vector multiplication (to give the cross product) is not (i.e., a × b = −b × a). The commutative law does not necessarily hold for multiplication of conditionally convergent series.

### What does a positive dot product mean?

A positive dot product means that two signals have a lot in common—they are related in a way very similar to two vectors pointing in the same direction. Likewise, a negative dot product means that the signals are related in a negative way, much like vectors pointing in opposing directions.

What are the properties of the dot product of two vectors?

Dot Product Properties of Vector: Property 1: Dot product of two vectors is commutative i.e. a.b = b.a = ab cos θ. Property 2: If a.b = 0 then it can be clearly seen that either b or a is zero or cos θ = 0 =. It suggests that either of the vectors is zero or they are perpendicular to each other.

## Which is the answer to the dot product?

The Dot Product gives a scalar (ordinary number) answer, and is sometimes called the scalar product. But there is also the Cross Product which gives a vector as an answer, and is sometimes called the vector product.

## Are there two ternary operations involving dot product?

There are two ternary operations involving dot product and cross product. The scalar triple product of three vectors is defined as. Its value is the determinant of the matrix whose columns are the Cartesian coordinates of the three vectors. It is the signed volume of the Parallelepiped defined by the three vectors.

Which is the dot product of a scalar projection?

The scalar projection (or scalar component) of a Euclidean vector a in the direction of a Euclidean vector b is given by where θ is the angle between a and b. In terms of the geometric definition of the dot product, this can be rewritten
