Hi, This isn't a homework problem per say but a question about the homework problems in textbooks assigned to upper-division undergraduates. To give some context: I am currently taking my last quarter of EM and using Griffith's book. Since the solution manual is very easily found online, pretty much all my peers(and I) are just using the solutions manual instead of actually doing the problems, and we all do pretty well on tests(though the problems are easier than the ones assigned in homework). My question is: are we really supposed to be able to do ALL of the problems in these textbooks? How badly are we shooting ourselves in the foot by not actually doing these problems? I feel that a lot of these problems involve mathematical tricks that would involve hours of playing around with the equations.
