Laws of vector operations
Vector operations, like many other mathematical objects, obey a few laws:
- Vector addition
- associativity
- commutativity
- identity element
- $\vec{A} + \vec{0} = \vec{0} + \vec{A} = \vec{A}
- Inverse element
- associativity
- Scalar multiplication
- associativity
- distributive law
- Distributive law for scalar addition
- identity element
- Unit vector
- Dividing a vector by its magnitude results in a vector of unit length, denoted by the caret symbol
