Hey Everyone, I am extremely glad to have found and joined the physicsforums community, and look forward to working and learning from others who share my enthusiam. I'm currently enrolled in Precalculus, but find the class to be a little slow and really scripted towards teaching students the HOW TO, but not the Why. I am really interested in moving beyond the superficial classroom and learning Calculus on my own. I have stumbled upon a few great resources including: Khan Academy PatrickJmt I plan on taking Calculus (I or II depending on how far I get in selfstudy) this coming spring at my local community college. For someone self-studying Calculus, do you think that these resources would be sufficient enough in preparing for/substituting a college level class in Cal I, possibly Calc II? I know I'll need to practice problems, so any workbooks that you would recommend would be helpful. In addition to the resources mentioned above, I've really been searching for a good book (or other resource) that would really walk me through the concepts of calculus and really teach me WHY and not just how. I first looked at books like "How to ace Calculus: a streetwise guide", but have read that these types of books are meant to go along with a course, and are not meant as selfstudy guides. Plus, they don't really explain the Why. Spivak and Apostol seem to be very prominent amongst the community, but after much research, I believe these books would be better approached after mastering the basic concepts of calc. I'm looking for a book that really explains the fundamentals, and everything else covered in a college course, without the rigor of an analysis book. Any help is much appreciated. Please be as specific as you can, Thank you!
