"Newton Premium Preservation Edition: Differentiation and Integration" Price: ¥3173 Content Introduction Mathematics is often said to be "difficult and not good at...", but among them, differentiation and integration may have a particularly strong image of being so. Differentiation and integration, in a word, are "mathematics for calculating change." Specifically, they are indispensable "tools" in the design of buildings, machines, and musical instruments, and in predicting economic trends, and they support our lives behind the scenes. Also, it can be said that the key to understanding the mechanisms of natural phenomena lies in differential equations. In this book, from the basics to the applications of differentiation and integration, we have carefully compiled them with "beautiful illustrations and easy-to-understand explanations unique to Newton" so that "you can enjoy reading it from zero knowledge." Through this book, please enjoy the profound world of differentiation and integration.
