Subspaces, basis, dimension, and rank
math.hmc.edu › ~dk › math40Dimension Example dim(Rn)=n Side-note since any set containing the zero vector is linearly dependent, Theorem. Any two bases of a subspace have the same number of vectors. proof by contradiction Definition The number of vectors in a basis of a subspace S is called the dimension of S. since {e 1,e 2,...,e n} = 1

https://mathforyou.net/en/online/vectors/basisThe basis in -dimensional space is called the ordered system of linearly independent vectors. For the following description, intoduce some additional concepts. Expression of the form: , where − some scalars and is called linear combination of the vectors . If there are exist the numbers such as at least one of then is not equal to zero (for example ) and the condition:
