I've used chapters of this book from the beginning of my BSc in Physics, now in my MSc in engineering and finally got a physical copy to accompany me for my PhD. It has been on "recommended reading" lists for almost all of my more mathematical modules for a good reason; it covers a lot of mathematical TOOLS needed for us applied folks : calculus (single, multivariate and vector), linear algebra, stats, numerical methods or even group theory!)<br><br>The book is big and aims to cover a lot of topics where quantity comes at the expense of depth, akin to general physics by Tipler &amp; Mosca, or similar texts by other authors.<br><br>I find the contents best used as a reference to brush up on some maths I might not have used in years, which I feel is the exact purpose of this book. Like other (undergraduate) reviewers I found it a bit lacking for learning the subjects from ground zero during my first years at uni but this is only to be expected with a subject such as mathematics. Having said that, it goes into enough depth to justify a lot of mathematical results at least for the target audience (i.e. not mathematicians, who are a level above us in the hierarchy of rigour).<br><br>Treat it as you would other general tools; you won't build a house with a penknife or discover the intricacies of the universe from an encyclopedia, but A LOT can be achieved with them nevertheless.
