Question

commutative law of dot product

​

Answer 1

Answer:

$\huge\boxed{♧Answer♧}$

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.
