Method'S mathematics, as the entire Method'X collection has an important advantage: it helps to assimilate the course through methods. If the definitions, theorems and other properties are not obvious to grasp and apply in a year, the price negotiated through methods and issues can quickly assimilate the concepts and how to apply them without any problem in all situations. From the moment you master the methods, it is not necessary to do hundreds of exercises to train before an exam: you know how to get out quickly, and you feel comfortable in each theme. The humor and laid back atmosphere of the book also participate in fun we used this book. I recommend it especially and the holiday notebook'S Method which is used with.
