| Teaching linear algebra independence via unique representation |
The important role of linear independence in introductory linear algebra is to guarantee the uniqueness of coordinates defined with respect to a basis. It is suggested that students might grasp the essential idea better if the idea of unique representation was stressed first, instead of either proceeding straight to a formal definition or first discussing examples of geometrical dependence of vectors.
