The application of the Fundamental Theorem of Linear Algebra is the constant theme of Professor Strang's lectures:http://mathworld.wolfram.com/FundamentalTheoremofLinearAlgebra.htmlI never heard of this theorem before these lectures, and I'm an Old Bastard. So this has been a fun learning experience!####[['Fundamental Theorem of Linear Algebra', 'Mathematical_Related_Concept', 'POS'], ['lectures', 'Course_General_Feedback', 'POS']]
