Ok I am sort of a math noob so bare with me. First and foremost, I am thinking about changing majors from boring Accounting to Mathematics and I now have a whole slew of questions. If I was initially a math major I would try to understand everything, just so you know. When you take the standard undergrad beginning math such as Calc 1-3, differential equations, linear algebra, are you expected to understand any of the proofs? Reason I ask is because I took Calc I at a community college and I feel it was made too easy to pass and I now feel I am missing what should have really been learned. Instead of going back and trying to figure out what I missed is there any specified courses that deal specifically with proofs and theories so that I can brush up on in the future what I maybe should have known? We never touched any proofs at all...not even epsilon delta proof, not even mentioned by teacher. So that is what I mean...is there any higher level courses that deal with it specifically? Are you expected to understand how to prove chain rule, power rule etc. in Calc I? Is this specifically dealt with in any other math courses?
