I wouldn't say this one is programmers-oriented either - it was posted to HN, sure, but maths and physics students could benefit from some visualizations too as a supplement to a more rigorous text.

As for the things you mentioned as omitted, I think if you want to do a complete treatment you have to introduce more mathematical prerequisites which limits the audience of your book. For a mathematician, I'd say classical linear algebra in itself is not particularly interesting - it's very well-behaved and pretty much "solved". What you care about is how it relates to other structures (groups, modules, fields), how it develops into other topics (functional analysis) and how it's used to study other objects (representation theory, tangent spaces of manifolds). In isolation, most of what's left is the computational aspect which is what non-mathematicians mostly care about.

My personal favorite is a former NASA employee who recorded a series of lessons for students to use to supplement their normal undergrad studies, prepare for exams, that kind of thing. He has a YouTube channel which has all sorts of topics (for free), but his site has paid videos on math, chemistry, electricity, some electronics, statistics, and a few other topics. You can find it on the high seas if you want a preview. Look up MathTutorDVD. It is not the end all, be all, but it is very helpful and I’ve learned in my own spare time lots. He covers high school math to Calculus 3 and probably beyond. I haven’t looked in a long time.

Khan Academy is also an option but I have not used it much so I can’t sufficiently comment on it. The things I’ve seen there have been decent and their main faculty are highly technical people who went into teaching. People have said great things about K.A., and likely they have a better way to track your progress and they might have better quizzes and tests.

One thing I remember specifically being called out is that majority of students who struggle with Calculus struggle almost exclusively due to linear algebra and formula manipulation. That the actual Calculus part is not the problem, it’s the lack of pre-requisite practice and learning more than anything.

The standard Calculus book by James Stewart will do. It covers most of the same. It is readable and quite affordable because it is so widespread.

A nice “1000 problems solved in Calculus” work book will also help. Practice is always good here, and it feels good when ideas learned from multiple sources work together.

Lastly, there are a couple of solid books that go into translating mathematical concepts so as to be usable in computer software, meaning how to take math formulas and turn them into usable algorithms. I want to bring to your attention their existence because eventually this is something that needs to be done, but trying to do everything at once will overwhelm you and distract you. It is however a “thing” when you get things down.

I recommend getting some notebooks - lined and square, a set of colored pens, and writing each and every exercise, lecture down. Color code notes, formulas, your own solutions and corrections. Grade yourself if need be. Keep your notebooks, labeled after each subject. I don’t know to what extent digital note taking is done today but I’ve always personally found it ineffective. So if you already self identify as a slow learner, writing things down in a meticulous way should help you greatly. Notebooks and pens are otherwise cheap, better to have an excess than not enough.

I hope this helps. I’m sure other people here have far better resources and I’ve forgotten all the stuff I used, but I’m not dead set on any one method.
