If you use advanced mathematics of Tongji University, then the unary calculus in the first volume is the basis of the next volume, otherwise you won't do the problem.

At present, Advanced Mathematics written by Yao of Peking University is commonly used in the Department of Economics. The first volume is about limit, unary calculus and multivariate calculus, as well as series and ordinary differential equations. The second volume is about linear algebra and probability theory. If you use this book, it can be said that it has little connection. Although calculus is the basis of continuous random variables in probability theory, it is generally only a conclusion, so it has little connection.

These two books are the main advanced mathematics textbooks commonly used here.
