Unit Vector Cross Product Rules
The cross product of two vectors and is a vector orthogonal to both vectors and is given by properties of cross product the cross product is a vector and there may a need as in eletromagnetism and many other topics in physics to find the orientation of this vector.
Unit vector cross product rules. Since the cross product must be perpendicular to the two unit vectors it must be equal to the other unit vector or the opposite of that unit vector. Cross product of two vectors will give the resultant as a vector. Hence by the geometric definition the cross product must be a unit vector. The scalar multipliers u1 u2 and u3are known as the components of uin the base described by the basevectors e1 e2 and e3.
Calculating the dot and cross products when vectors are presented in their x y and z or i j and k components. The dot product of two unit vectors behaves just oppositely. Similar to the gradient where each axis casts a vote for the direction of greatest increase. The direction of n is determined by the right hand rule which will be discussed shortly.
6 components 6 votes and their total is the cross product. It is zero when the unit vectors are perpendicular and 1 if the unit vectors are parallel. A b ab sin o n. Since this product has magnitude and direction it is also known as the vector product.
The vector n n hat is a unit vector perpendicular to the plane formed by the two vectors. When the vectors are crossed each pair of orthogonal components like ax by a x b y casts a vote for where the orthogonal vector should point. Calculating the dot and cross products when vectors are presented in their x y and z or i j and k components.

Given two unit vectors their cross product has a magnitude of 1 if the two are perpendicular and a magnitude of zero if the two are parallel. The cross product is distributive a b c a b a c. If youre seeing this message it means were having trouble loading external resources on our website.
