Hey all. I've recently graduated high school and will be entering college this fall. I managed to get my hands on an inexpensive copy of of Griffith's Introduction to Quantum Mechanics and thought I'd jump on the opportunity to teach myself something I have immense interest in. I started reading the first chapter, and quickly found myself overcome by the difficulty of the mathematics involved. I've done my fair share of mathematics - teaching myself the introductions to differential equations and linear algebra. I've already done the equivalent of Calculus I and II. I was wondering simply, should the math be this difficult? In fairness, I haven't really taken a class in differential equations so much as taught myself the basics, and my linear algebra skills are marginal at best. I managed to wade through several of the problems and got correct answers on my own, but some are simply way over my head. Thanks for any help.
