... A translation by a nonzero vector is not a linear map, because linear maps must send the zero vector to the zero vector. However, translations are very useful in performing coordinate transformations. I’ll introduce the following terminology for the composite of a linear transformation and a transla ...

... plane P through the origin is spanned by any two non collinear vectors on P , and two any two non collinear vectors on P are linearly independent. Thus P has a basis consisting of two vectors. It should noted that the trivial vector space {0} does not have a basis, since in order to contain a linear ...

... A linear, homogeneous differential equation is constant-coefficient if the coefficient functions f0 (x), f1 (x), . . . , fn (x) are constants. For example, a second-order constant-coefficient linear homogeneous differential equation has the form a1 y 00 + a2 y 0 + a3 y = 0, where a1 , a2 , and a3 ar ...

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.
