Hey guys, I'm a junior electrical engineering major. I took vector calculus last year, and I don't remember too much. Next semester I am taking Electromagnetics, so I want to brush up on my line and surface integrals and all that stuff. Do you guys have any advice where I could go to reteach myself some of that? Websites, specific books, study aids, anything. I probably won't buy a textbook, but I would consider buying a study guide. Thanks a lot!
