Calculus

Standard calculus textbooks

These books are those designed to be the required textbook for a standard high school or university calculus course. Many of them have had a large number of revisions, which makes it likely that you can find slightly older but still perfectly useful copies on the used market. They try to have everything – proofs, intuitive explanations, illustrations, problems – but they aren’t necessarily great at anything. These books are widely derided by math majors, though I suspect this to be in part motivated by elitism and by grad students’ dislike of teaching lower-level math courses. In any case, these are useful even if you just want a cheap source of problems to practice with.

The OpenStax series follows a very common sequencing of topics, which I list here as a representative of what you can expect to find in the books in this section. OpenStax splits these into three separate books, but most series combine them all into one huge book of about 1000 pages. It’s also common to see 1 & 2 combined, and a separate book for 3.

Here are some books in this category, including the most popular ones that I know of. I’ve tried to link mainly to the best-priced editions so you can get a book for $5-10 (though prices change).

Elite calculus textbooks

These are books that math majors get enthusiastic about. They are typically used in elite universities and honors courses. They emphasize theory from the ground up beginning with the real number system, but they have fewer calculation problems and applications problems (no applications, in some cases). Note that many, maybe most students who read these books do not actually start calculus with them: often they’ve seen calculus before, maybe they’ve even had a course or two.

Other textbooks of note

These books don’t fit cleanly into the categories that I described above.

Intuitive approaches

These take the attitude that emphasis on rigorous proofs gets in the way of understanding calculus.

Online calculus resources

MIT OCW has a series of online lectures for calculus. The lecturing isn’t outstanding, but the material covered is good for the most part. The lectures can be watched on YouTube here:

Other online lecture offerings include ones from Ohio State and Khan Academy. Both seemed a bit slow and basic for my taste, whereas MIT’s was more my speed, but then again I’d already taken some calculus in high school so I wasn’t starting from scratch.

The University of Wisconsin-Madison also has free calculus texts that you can get online; they don’t look at all adequate as stand-alone texts for self study, but they do have problems with some solutions included. Whitman College also has free calculus texts.

Vector calculus

For multivariate calculus, there seems to be a general consensus that the texts that teach “all” of calculus don’t do a great job with it. (Leithold, for example, stops giving so many proofs at that point in the curriculum and states that they belong in a book dedicated to the subject.) The following texts are dedicated to this part of the calculus curriculum in particular (arranged in descending order according to my impression of their usefulness):

The Feynman Lectures also discuss vector calculus in the context of electromagnetism, which is supposedly a great way to tie it in with your understanding of the physical, if you already have some background in physics. See Physics.

Calculus problem books

It may be that the problems in whatever textbook you’re using don’t give you as much practice as you want. One option is to get another textbook and do the problems from that, too. However, there are a number of books dedicated to providing problems. One advantage to these is that they generally tend to give you explanations of how to solve them as well.

John Erdman of Portland State University has posted a number of free problem books as PDFs on his website (answers to odd-numbered exercises given): http://web.pdx.edu/~erdman/

Advanced Calculus

The term “advanced calculus” seems to be somewhat vague. Sometimes it means calculus of several variables, sometimes it means analysis, sometimes it means applications that become possible after you have a couple of years of calculus under your belt. The ones I list here straddle the line between calculus and analysis.
