This book is a companion volume to Essential Mathematics for Economic Analysis by Knut Sydsaeter and Peter Hammond. The new book is intended for advanced undergraduate and graduate students of economics whose requirements go beyond the material usually taught in undergraduate mathematics courses for economists. It presents most of the mathematical tools that are required for advanced courses in economic theory - both micro and macro.
I have found this book to great at teaching many of the mathematical tools needed for the economics, especially the many different optimisation problems with multivariabel calculus and linear algebra. Though i would have liked the linear algebra section to include that of the first book more in depth rather than a brief review (Essential Mathematics for Economic Analysis). It could also at times feel very difficult due to the mathematical rigour. It has many problems/excercises that are of economic nature and of a practical nature to solve and learn. All in all this book has been a great learning experience.
