In vector algebra a branch of mathematics 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 productThere 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.. The vector triple product is defined byScalar Product of Vectors. The scalar product and the vector product are the two ways of multiplying vectors which see the most application in physics and astronomy. The scalar product of two vectors can be constructed by taking the component of one vector in the direction of the other and multiplying it times the magnitude of the other vector. This can be expressed in the form

In this section we will discuss the mathematical and geometric interpretation of the sum and difference of two vectors. We also define and give a geometric interpretation for scalar multiplication. We also give some of the basic properties of vector arithmetic and introduce the common i j k notation for vectors.Definition of a vector. A vector is an object that has both a magnitude and a direction. Geometrically we can picture a vector as a directed line segment whose vectorgth is the magnitude of the vector and with an arrow indicating the direction.The dot product between two vectors is based on the projection of one vector onto another. Lets imagine we have two vectors vca and vcb and we want to calculate how much of vca is pointing in the same direction as the vector vcb.

Defining the Cross Product. The dot product represents the similarity between vectors as a single number. For example we can say that North and East are 0% similar since (0 1) cdot (1 0) 0. Or that North and Northeast are 70% similar (cos(45) .707 remember that trig functions are percentages.)The similarity shows the amount of one vector that shows up in the other.In mathematics the dot product is an operation that takes two vectors as input and that returns a scalar number as output. The number returned is dependent on the vectorgth of both vectors and on the angle between them. The name is derived from the centered dot that is often used to designate this operation the alternative name scalar product emphasizes the scalar (rather than vector Vector Questions a selection of answers from the Dr. Math archives.
