CHAPTER 6. LINEAR EQUATIONS Part 1. Single Linear Equations
... For a quick example, we note that vectors u = (1, 0) and v = (1, 1) are linearly independent. To see this, we take a linear relation au + bv = 0. Then a(1, 0) + b(1, 1) = (0, 0), or (a + b, b) = (0, 0), that is, a + b = 0 and b = 0, which give a = 0, b = 0. The converse of linear independence is li ...

Basis (linear algebra)
Basis vector redirects here. For basis vector in the context of crystals, see crystal structure. For a more general concept in physics, see frame of reference.A set of vectors in a vector space V is called a basis, or a set of basis vectors, if the vectors are linearly independent and every vector in the vector space is a linear combination of this set. In more general terms, a basis is a linearly independent spanning set.Given a basis of a vector space V, every element of V can be expressed uniquely as a linear combination of basis vectors, whose coefficients are referred to as vector coordinates or components. A vector space can have several distinct sets of basis vectors; however each such set has the same number of elements, with this number being the dimension of the vector space.
