I just finished up calc II this semester. So far, seems fairly easy and I got an A no problem. However, there was a lot of material in each of the chapters that we didn't cover as well as more difficult problems in the sections that we didn't work on. Our professor told us it really isn't feasible to try to learn how to do the most difficult sections of most chapters because it is just too time-consuming and that any of the more in-depth material that you need to know for your major will be covered more extensively later on. So, on that note, I do want to put at least some of my study time into calc, but I also don't want to waste time on stuff I won't use much later on. I want to start learning computer programming over the break and start working on the Morin book for classical mechanics. So, what type of stuff from calc I to calc II is really important later on? What would be worthwhile putting practice into to improve on? I have heard so far that the hyperbolics really aren't too important since you hardly ever see them later on, but I'm not sure what I should try to improve on? I know this is difficult to answer generally speaking, but I guess if I could get an idea of what I will see more of later on in physics, I will know where I could most productively spend my time on calc? The only feedback beyond the hyperbolics that I have gotten so far is that natural log, exponential functions, and sin/cos functions pop up a lot in physics, so it's good to have the derivatives and integrals of those down solid. Any additional feedback would be greatly appreciated.
