Oh, differential equations. I'm doing ECE at university now and I have an exam in about 7 weeks. I've found that it's quite hard to identify what sort of differential equation a given problem is, and then how to solve it. However I've found that by looking around for other material I can understand it better. For example web searching "type 4 differential equation" bought up this gem: https://www.math.ucdavis.edu/~thomases/W11_16C1_lec_1_7_11.pdf https://www.math.ucdavis.edu/~thomases/W11_16C1_lec_1_7_11.p... I think I'll try out Khan Academy because I've found that the lecturer's problem sheets probably aren't enough on their own.
