自从1908年出版以来，这本书已经成为一部经典之著。一代又一代崭露头角的数学家正是通过这本书的指引，步入了数学的殿堂。
在本书中，作者怀着对教育工作的无限热忱，以一种严格的纯粹学者的态度，揭示了微积分的基本思想、无穷级数的性质以及包括极限概念在内的其他题材。
作者简介
G. H.Hardy英国数学家(1877—1947)。1896年考入剑桥三一学院，并子1900年在剑桥获得史密斯奖。之后，在英国牛津大学。剑桥大学任教，是20世纪初著名的数学分析家之一。
他的贡献包括数论中的丢番图逼近、堆垒数论、素数分布理论与黎曼函数，调和分析中的三角级数理论。发散级数求和与陶伯定理。不等式、积分变换与积分方程等方面，对分析学的发展有深刻的影响。以他的名字命名的Hp空间(哈代空间)，至今仍是数学研究中十分活跃的领域。
除本书外，他还著有《不等式》、《发散级数》等10多部书籍与300多篇文章。
