Hehe, everyone is all like, "Boyce and DiPrima's Elementary Differential Equations and Boundary Value Problems"!
A little while ago, I was at UBC Main Library (the new one, with the three-story steel array) and I was looking for a book on the shelves. I couldn't find it, so I wandered around that aisle for a few minutes. One book I noticed was Boyce and DiPrima, &c, because it's got several mentions in this neat handbook I have. The cover seemed unusual for some reason, and it drew my attention. There were two copies there, and another copy at the other end of the aisle - it must have been misfiled or something. There were so many of them!
On the way home, I remembered something, and so later (the next day), I looked at my bookshelf. Yes, the name was familiar; I had bought the book at least half a year ago from ABC!* I proceeded on the principle that the best stuff is usually hidden, and I checked the little stacks of books at knee-level, the ones nobody looks at. One of the books was Boyce and DiPrima, and I was curious, so I bought it. It cost a shiny dollar.
I kept on reading in my handbook, and it seemed like almost all of the entries I was looking at had some kind of reference like, "Also see Boyce and DiPrima [3, pages 140-156]," and similar to that.
And then I found this entry just now, so I said, "oh no!"
Truly it is a well-known book! Good, though?
*And then ignored it completely (after reading a little and learning about "Lyapunov functions," namely functions f(x', x) that decrease with time and that have a local minimum "nearby"; and the stability of a linear system (Near a fixed point (It depends on the Jordan form.).).)
