We prove the trace of a product of two nxn matrices A and B is the same regardless of the order in which A and B are multiplied. That is, we prove tr(AB) = tr(BA).
This is a great explanation that is so helpful for a beginner like me! Too many math teachers don't take the trouble to explain the terms bit by bit. I'm so glad this video exists 🖤 thank you and kudos!!
@@just_a_carl I was desperately looking for a channel like yours because I'm back in academia after 10 years of not doing hand calculation and really, really need to work on my ODE and PDE. Just checked out your playlists and I saw you have one for multivariable calculus, yay! Subscribing :D
You're very welcome! Thanks for watching.
Thanks. It was really helpful :)
This really helped. Thank you so much!
You are most welcome! Wow - this video is 11 years old! How time flies!
