卓里奇数学分析第一卷。我们本科教的微积分忽视了对于集合尤其是数集（自然数、有理数、实数、复数）结构的讨论，而且微积分很多概念如连续、导数、黎曼积分阐述不明，容易在推导中导致错误结论，请参看上册(Charidge is the first in mathematical analysis. We ignore the science of calculus for set number set (especially natural numbers, rational numbers, real and complex) structure are discussed, and a lot of calculus concepts such as continuous, derivative, integral of Riemann is unknown, easily lead to wrong conclusions in the derivation, please refer to the list)
