Mainly because their contents are different, the content of Gao Shu 1 is mainly calculus. The content of advanced mathematics 2 is probability theory and mathematical statistics. High number 2 needs to be based on high number 1, so generally learn high number 1 first.

Another French mathematician, Lagrand, established one of several mean value theorems in differential calculus, which made up for the deficiency of Rolle theorem and established Lagrange multiplication.

L'H?pital, a French mathematician, established L'H?pital's law in 1696 and published infinitesimal analysis of curves, which is the earliest textbook in calculus. L'H?pital's law is a derivative method of Cauchy's mean value theorem combined with infinite limit, which realizes a simple and practical mathematical principle.
