The scalar triple product - Math Insigh

The scalar triple product of three vectors a, b, and c is (a × b) ⋅ c. It is a scalar product because, just like the dot product, it evaluates to a single number. (In this way, it is unlike the cross product, which is a vector. Scalar triple product formula means the dot product of one of the vectors with the cross product of the other two vectors. It can be written as: [a b c] = (a x b).c The formula signifies the volume of the parallelepiped whose three coterminous edges denote three vectors, say, a, b and c Properties Of Scalar Triple Product Of Vectors Let us see some more significant properties of the STP: (i) The STP of three vectors is zero if any two of them are parallel. This implies as a corollary that [→a →a →b] = 0 [ a → a → b →] = 0 (always Scalar triple product is one of the primary concepts of vector algebra where we consider the product of three vectors. This can be carried out by taking the dot products of any one of the vectors with the cross product of the remaining two vectors and results in some scalar quantity as the dot product always gives some particular value

For any three vectors, and, the scalar triple product (×) ⋅ is denoted by [ ×, ]. [ ×, ] is read as box a, b, c. For this reason and also because the absolute value of a scalar triple product represents the volume of a box (rectangular parallelepiped),a scalar triple product is also called a box product The scalar triple product is a pseudoscalar (i.e., it reverses sign under inversion). The scalar triple product can also be written in terms of the permutation symbol as (6) where Einstein summation has been used to sum over repeated indices Scalar triple product is one of the important concepts of the vector algebra in which we take the product of three vectors. This can be performed by taking dot product of one vector with the cross product of the other two vectors and results in some scalar quantity as dot product always gives some particular value

The vector triple product is defined as the cross product of one vector with the cross product of the other two. The following relationship holds, where a, b and c are vectors: a x (b x c) = (a•c)b - (a•b)c Clearly, this is a vector, since (a•c) and (a•b) are scalars The value of this product is clearly 0 by the properties of triple scalar products (see Appendix A.3), hence coplanarity has been shown.
