Based on 5th ed. I prefer this to Engineering Mathematics with Stroud, most of the time. Both are good for looping back over a wide range of maths. This volume tends to be more concise than Stroud and the layout/diagrams/print are better - sharper, well done, and succinct. Where Stroud is more verbose and geared toward actually educating via example/process this volume skips that and provides the meat and potatoes, it just doesn't show you how to eat. In my view that is a benefit when you don't want to wade through process example to get to what you are looking for. Still keep both around, just tend to refer to this one more.
