Looking for good calculus teaching website I'm looking for any free resource (which you will most likely post in the form of a website) which you dictate as a great resource to learning calculus. I am currently in Calc 1, but I'm getting my rear-end handed to me. I have difficulty in understanding my textbook, but not all of the textbook. I'm looking for something that would be a great supplemental aid in learning calculus. Something like "Learning calc for dummies" would get me the basic concepts and understanding, then I apply that in terms of my textbook. Obviously the best guide would be an in-depth, easy to understand resource that could replace the textbook in most, if not all, areas. Anything you guys can give would be awesome! Thanks!
