The Orthogonal Group
Channel: Andrew Misseldine
Date: 2020-12-03

In this video, we review properties about transposition of real matrices and orthogonal matrices from Linear Algebra. With this in hand, we present the orthogonal group O(n) and the special orthogonal group SO(n), with examples, and discuss briefly their importance as classical matrix groups.
