1. Different book specifications lead to different cover areas.
For mathematics books, the specifications are different, including large textbooks and portable reference books. So the area of different covers will also change. However, generally speaking, the cover size of a math book is about 18x25.
2. Different coverage areas do not affect the quality of internal knowledge.
The cover size of a math book does not represent the quality of the knowledge it contains. Regardless of the size of the cover, the knowledge in the book has been carefully sorted out and reviewed by professionals, supported by scientific theories and with high authority.
It is more important to choose the book that suits you.
For math lovers, it is more important to choose books that suit them. Whether the content of a book is rich and accurate and whether it can meet your own needs is the key issue to consider when choosing a book, not the cover size of the book.
How to choose a math book that suits you?
1, determine your goals and needs.
When choosing a math book, you need to determine your needs and goals first. If you want to learn mathematics knowledge in a certain field systematically, then you need to choose the corresponding teaching materials or professional books. If you just want to know the solution to a specific problem, you can choose reference books related to the problem.
2. Know the author and publisher of the book.
When choosing a book, you also need to know the author and publishing house of the book. A good author can guarantee the quality, and a good publishing house can guarantee the authenticity and printing quality.
3. Refer to other people's comments and opinions.
On the Internet, you can check other readers' comments and opinions on this book, and you can also ask friends or teachers who know math. In this way, we can have a more comprehensive understanding of the content, difficulty and suitable readers of the book.
