BaseVector

BaseVector[ n1, n2 (, n3) ]

BaseVector[ n1, n2 (, n3) ] represents the mathematical concept of a basis vector, where n1 represents the change in horizontal direction, and n2 represents the change in the vertical direction. A vector in basis vector notation is written in the form n1 i + n2 j.
