Dimension of a Vector Space | Linear Algebra

Показать описание
We define the dimension of a vector space by first looking at some important facts concerning the number of vectors in a basis for a vector space. We then see some familiar examples of vector spaces and their dimensions, including R^n, Pn, and Mmn, and finish by finding the dimension of the solution space of a homogenous linear system. #linearalgebra

How weird. I clicked to watch this video and Youtube said I wasn't subscribed. So I subscribed again and immediately appeared that the bell was activated ... Youtube's bug?
