Hey all, I'm new here. I was just looking at a problem set from Florida Atlantic University from 2010 (http://www.physics.fau.edu/~cbeetle/Fall10/PHZ5115/Assignments/pset3.pdf) and it looks absolutely ridiculous. I'm taking a course now as a sophomore called "Mathematical Methods in the Physical Sciences" and we're using Boaz as our textbook. We haven't gone over any of this crazy looking stuff, should I be worried? Thanks.
