- As explained below, the cross product can be expressed in the form of a determinant of a special 3 × 3 matrix. According to Sarrus's rule, this involves multiplications between matrix elements identified by crossed diagonals.

In geometry and algebra, the triple product is a product of three 3-dimensional vectors, usually Euclidean vectors. The name "triple product" is used for two different products, the scalar-valued scalar triple product and, less often, the vector-valued vector triple product.
In mathematics, the cross product or vector product (occasionally directed area product, to emphasize its geometric significance) is a binary operation on two vectors in a three-dimensional oriented Euclidean vector space (named here ), and is denoted by the symbol .
Oct 2, 2023 · The Triple Scalar Product. Because the cross product of two vectors is a vector, it is possible to combine the dot product and the cross product. The dot product of a vector with the cross product of two other vectors is called the triple scalar product because the result is a scalar.
The cross product of two vectors a and b gives a third vector c that is perpendicular to both a and b. The magnitude of the cross product is equal to the area of the parallelogram formed by a and b. The base of this parallelogram has length |a|, and the height has length |b| sin (theta).

This product, like the determinant, changes sign if you just reverse the vectors in the cross product. The vector triple product, A(BC) is a vector, is normal to A and normal to BC which means it is in the plane of B and C. And it is linear in all three vectors.
The vector triple product (also called triple product expansion or Lagrange's formula) is the product of one vector with the product of two other vectors. If u, v and w are 3 vectors, then the vector triple product operation is u×(v×w).
