Ma Zuqiang is a Chinese author about whom limited public information is available. At present, it is known only that one book appears under his name, namely Calculus. According to the library's classification, the book is placed in the examination category, suggesting that its writing and publication are oriented toward exam preparation and study support, and that it may be used by readers as review material or within a supplementary teaching series. Calculus is itself a foundational subject in higher mathematics, with a large and steady body of examinees; books of this kind usually emphasize the organization of key concepts, mastery of formulas, and practice in problem solving, so this volume can be understood in light of the general features of similar study guides.
