Isomorphic Vector Spaces and Isomorphisms | Linear Algebra

We introduce vector space isomorphisms and isomorphic vector spaces. We'll see several examples of isomorphic vector spaces and isomorphisms between them, and we'll prove a fundamental theorem stating that two finite-dimensional vector spaces are isomorphic if and only if they have the same dimension. This means every n-dimensional vector space is isomorphic to R^n. We'll also see the isomorphism from an n-dimensional space to R^n. #linearalgebra
