Cross Product Wikiversity The cross product, also known as the "vector product", is a vector associated with a pair of vectors in 3 dimensional space. the cross product is perpendicular to the vectors a and b, and points in the direction of the thumb of the right hand when the fingers curl in the direction to move a to b. Given two linearly independent vectors a and b, the cross product, a × b (read "a cross b"), is a vector that is perpendicular to both a and b, [1] and thus normal to the plane containing them. it has many applications in mathematics, physics, engineering, and computer programming.
Cross Product Wikiversity A vector has magnitude (how long it is) and direction: two vectors can be multiplied using the cross product (also see dot product). The cross product, also known as the vector product, is a binary operation that takes two vectors in a three dimensional euclidean space and produces another vector. Cross product, a method of multiplying two vectors that produces a vector perpendicular to both vectors involved in the multiplication; that is, a × b = c, where c is perpendicular to both a and b. The cross product will always be orthogonal to the other two vectors and must remain a right hand triple since the cross product would have to reverse direction in order to have the triple transform into a left hand triple.
Properties Of The Cross Product Cross product, a method of multiplying two vectors that produces a vector perpendicular to both vectors involved in the multiplication; that is, a × b = c, where c is perpendicular to both a and b. The cross product will always be orthogonal to the other two vectors and must remain a right hand triple since the cross product would have to reverse direction in order to have the triple transform into a left hand triple. The cross, or vector, product of two vectors a → and b → is denoted by a → × b →. it is defined as a vector perpendicular to both a → and b → (that is to say, to the plane that contains them both), with a magnitude given by (9.3.1) | a → × b → | = a b sin θ. Finally, we will take a look at some algebraic properties of the cross product. most of these are similar to the properties of the dot product, but there is one important difference. The cross product is useful because ~v ~w is perpendicular to both ~v and ~w. you can directly show this by taking the dot product ~v (~v ~w) and check that it is zero. The answer is, "nothing: you can't cross a scaler with a vector," a reference to the fact the cross product can be applied only to two vectors and not a scalar and a vector (or two scalars, for that matter).
