 PlanetMath: triple scalar product The triple scalar product of three vectors is an extension of the cross product. Thus, the magnitude of the triple scalar product is equivalent to the volume of the parallelepiped formed by the three vectors. The latter is implied by the properties of the cross product. planetmath.org /encyclopedia/TripleScalarProduct.html   (238 words)

 Vector Operations Scalar Product: The simplest way to multiply two vectors is called the   scalar product (often called the   dot product). We usually use the scalar product when what is important is not the whole magnitude of a vector, but only its magnitude along some direction. There are several ways to compute the vector product, but the most useful way for this course is to memorize the rules for the cross products of the unit vectors. maxwell.byu.edu /~spencerr/websumm122/node8.html   (738 words)

 Vector : Scalar product   (Site not responding. Last check: 2007-10-08) First, the absolute value of the box product is the volume of the parallelepiped which has edges that are defined by the three vectors. Second, the scalar triple product is zero if and only if the three vectors are linearly dependent, which can be easily proved by considering that in order for the three vectors to not make a volume, they must all lie in the same plane. In coordinates, if the three vectors are thought of as rows, the scalar triple product is simply the determinant of the 3-by-3 matrix having the three vectors as rows. www.eurofreehost.com /sc/Scalar_product_6.html   (325 words)
