Reddit mentions of Advanced Engineering Mathematics

I would strongly suggest you get a textbook called "Advanced Engineering Mathematics" (you can buy used cheap) - you won't need everything in it most likely, but it covers a huge amount of material and can be used as a reference as well as a textbook. Rather than spending a lot of time giving you examples and explaining topics it has a format where it presents a theorem, proves it, gives you one example, then moves on to the next theorem then gives you a set of problems which you can work through. In this way it fits differential equations, linear algebra, vector algebra, multivariable calculus, as well as some complex analysis and partial differential equations into one book.

You can skip all the differential equations generally and go straight for the Linear algebra and vector parts.

I took my Differential Equations class with a DiffEq textbook by the same textbook author (Dennis Zill - all his students hate him) - it was the first time I ever remember a math textbook standing out to me in my math courses. I absolutely love the book A.E.M. and would never keep it far from me while programming even if I only need it occasionally. If I were required to dispose of my entire library and was allowed to keep only two books - I would keep the OED and that textbook.

When I went back to grad school I took an advanced engineering math class based on the book:

Looking at the table if contents it's VERY comprehensive. Maybe too comprehensive.... And it doesn't mention probability and statistics.
