Hi there, fellow physics forums members & guests. I'm starting the 1st semester of grad school, and I'm faced with a tough choice between two different classes. I could take Intermediate Analysis 1 or Applied Linear Algebra. The only course I've taken involving proofs is Discrete Math, and I had no problem there. However, I am concerned that since I have never been exposed to Advanced Calculus, the Intermediate Analysis 1 course could destroy me. On the other hand, I would really need to understand this stuff, if I am going to get a PhD. I am working on a Masters degree, and I would like to move on with my life and start working in the real world. As far as Applied Linear Algebra goes, I'm not worried. I took Linear Algebra as an undergrad and rocked it. Anybody have any insights to offer? Is Analysis impossibly hard to understand without prior exposure?
