Basis Vector
A basis vector in an n-dimensional vector space is one of any chosen set of n vectors in the space forming a vector basis, i.e., having the property that every vector in the space can be written uniquely as a linear combination of them.
For example, in the Euclidean plane, the unit vectors e^->_1=(1,0) and e^->_2=(0,1) form a vector basis since for any point (x,y),
| (x,y)=xe_1+ye_2, |
so for this basis, e^->_1 and e^->_2 are basis vectors
