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 $${\displaystyle E}$$), and is denoted by the symbol See more 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 … See more Coordinate notation If (i, j, k) is a positively oriented orthonormal basis, the basis vectors satisfy the following equalities See more Conversion to matrix multiplication The vector cross product also can be expressed as the product of a skew-symmetric matrix and a vector: The columns [a]×,i of the skew-symmetric matrix for a vector a can be also obtained by calculating the … 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 dimensions. This view allows a natural geometric interpretation of the cross product. In exterior algebra the exterior product of … See more In 1842, William Rowan Hamilton discovered the algebra of quaternions and the non-commutative Hamilton product. In particular, when the Hamilton product of two vectors (that is, pure quaternions with zero scalar part) is performed, it results in a quaternion with a … See more Geometric meaning The magnitude of the cross product can be interpreted as the positive area of the parallelogram having … See more The cross product has applications in various contexts. For example, it is used in computational geometry, physics and engineering. A non-exhaustive list of examples follows. See more WebCross Product Definition. The cross product is a binary operation on two vectors in three-dimensional space. The symbol that is used to denote the cross product is ×. It is also called a vector product. Sometimes it is referred to as direct area product to accentuate the geometric significance.
