If you want to work additional problems, go on Amazon or Alibris or whatever and buy a cheap used copy of one of the enormous Calculus books, and/or a Shaum's Outlines book on Calculus, or one of those "1001 solved problems in $SUBJECT" books. Just restart the video when you finish the problem or if you get stuck. Listen, take notes, and then when he puts an example on the board pause the video and work through the example. Note that most of his lectures are live lectures to an actual class, so IMO the best way to approach it is to pretend you're right there in class. and treat any Calculus they learn as "found money." But assuming you remember at least a little algebra and really want to learn Calculus, I think he's one of the best at teaching it. TBH, I think a person who wanted to learn the equivalent of high-school algebra could just about doing it by watching his Calc I series. So he does a very thorough job of explaining all of the subtle algebraic manipulations that go on as he works through derivatives, integrals, etc. He points out that most students who struggle with Calculus struggle because they (never mastered | forgot | whatever) their basic Algebra. And in particular because he is very detailed in his explanations. I consider him one of the best lecturers in math education, at least for these subjects. > Does anyone know any other good resources for learning calculus at home? Even though I understand how NSA works, I'd prefer to use any of those. Many approaches to Calculus do not require assertions about the existence of sets that we cannot construct, even in principle. And therefore NSA can prove anything about Calculus that I care about without needing any axiom beyond ZF.īut in the end this is using a mathematical sledgehammer to drive in a thumb tack. That which we can actually calculate in any useful way can all be calculated on a computer. And we know that it is true without any additional axioms beyond ZF! So take any calculation we can talk about that can be approximated on a computer. (Note, they must be statable in PA, but not necessarily provable there.) But PA can encode any statement we can make about computation. ![]() How is this possible? From Shoenfield's absoluteness theorem, you can prove that all statements that an be made in the Peano Axioms that can be proven in ZFC, are also true in ZF. But for all cases I care about, I can already prove it with NSA without ANY additional axioms! I find it a mildly interesting intellectual exercise that you can do NSA with weaker axioms than choice. The axiom of choice is necessary to prove the existence of non-principal ultrafilters in (choice-free) set theory, but the existence of non-principal ultrafilters is not sufficient to prove the axiom of choice. Essentially, the set of properties satisfied by a fixed nonstandard hypernatural gives rise to a non-principal ultrafilter over the naturals. The three axioms of Hrbacek and Katz presented in the article "Infinitesimal analysis without the Axiom of Choice" are the best recent example: these axioms allow you to do everything that is done in Keisler's book and more (including defining the derivative), and you never need to invoke the axiom of choice to justify them. However, there are axioms for nonstandard analysis which are conservative over the usual choice-free set theory ZF. Only model-theoretic approaches, which justify the infinitesimal methods by constructing a hyperreal field, require (a weak form of) the axiom of choice. ![]() You write, "we shouldn't need the axiom of choice to define the derivative."
