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: . This is known as triple product expansion, or Lagrange's formula, although the latter name is also used for several other formulas. Its right hand side can be remembered by using the mnemonic "… Weba b a b proj a b Alternatively, the vector proj b a smashes a directly onto b and gives us the component of a in the b direction: a b a b proj b a It turns out that this is a very useful …

Scalar Triple Product - Properties, Formula and Solved Examples

WebProperties of the cross product: If a, b, and c are vectors and c is a scalar, then 1. a x b = –b x a 2. (ca) x b = c(a x b) = a x (cb) 3. a x (b + c) = a x b + a x c 4. (a + b) x c = a x c + … The cross product of two vectors a and b is defined only in three-dimensional space and is denoted by a × b. In physics and applied mathematics, the wedge notation a ∧ b is often used (in conjunction with the name vector product), although in pure mathematics such notation is usually reserved for just the exterior … See more 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 See more Coordinate notation If (i, j, k) is a positively oriented orthonormal basis, the basis vectors satisfy the following equalities which imply, by the anticommutativity of the cross product, that See more Conversion to matrix multiplication The vector cross product also can be expressed as the product of a skew-symmetric matrix and … See more The cross product can be defined in terms of the exterior product. It can be generalized to an external product in other than three … See more In 1842, William Rowan Hamilton discovered the algebra of quaternions and the non-commutative Hamilton product.
