Advanced Engineering Mathematics was the standard text book that was used in India by all the top engineering institutes.  I used it and so did my brother in the late 1970s/ early 1980s.  It doesn't teach you about math concepts.  It has practical engineering applications/ examples to show the reader as to how to apply these math concepts in real life engineering problems.  Very few engineering math books do this to show the practical application of math concepts.  That is what makes this book a top notch read.  Otherwise, math is just a few algebriac steps which defeats the very purpose of studying engineering math.  But this book is different.  I recommended this book to both my sons.  My first son enjoyed it a lot.  My second son is enjoying it.  He likes the direct approach without being verbose.
