Hi guys, I had taken Calc 1, Calc 2, Calc 3, ODE and Linear Algebra in university, in the range of 5 to 7 years ago. I am about to go back to school, how should I re-teach myself calculus? Back then I used Stewart (Calc 1/2), Adams (Calc 3), and DiPrima/Boyce (ODE) for Calculus and ODEs. In each of those classes, I did OK for the most part, worst grade was in ODE with a C, got an A for Calc 3 (multi-var calculus and series). I studied Economics back then, now I am going back to school for Chemistry and a little worried about Physical Chemistry and Quantum Chem classes and their heavy use of Calculus, which I had mainly forgotten. I had gotten a copy of Courant to (hopefully) teach myself Calculus starting from the Single Variable, but in a more ground up, rigorous way. I would like to relearn everything but not so much the computational side of things; like how to find derivatives/integral of some function, but more on developing intuitions and strong fundamentals on calculus. Is this the right way to approach this? Which book should I use? I have the Courant book, still have my Adams and DiPrima/Boyce books as well How should I approach this? How should I brush up on this? How advanced would one's Calculus knowledge for Physical Chemistry/Quantum Chemistry? Thank you so much.
