I'm a physics major taking Linear Algebra right now. It's been pretty boring but I'm doing well. I'm just wondering about which concepts from this subject should I really focus on understanding and knowing how to apply well? Obviously I'm focusing on everything and trying to receive and A in the course. I am just curious as to what other physics majors who have been through this have taken from this course as being very valuable. Thanks in advance to whomever replies and gives me some nuggets of wisdom!
