Lately, I have become interested in learning math methods (actually reviewing, because I have taken a math methods course already). I have watched some of Prof. Strang's (MIT) Math Methods for Engineer videos, and couldn't say that I was a big fan of that video series. For one, it was for graduate students, and seemed to assume some knowledge of math methods already. I was wondering if there is another resource somewhere that's really good for learning math methods. Video lectures similar to the ones offered by Prof. Susskind (Stanford) would be great, or good course notes on math methods would be good as well. I feel that such a resource would be good for any physics student.
