The textbooks of the Department of Applied Mathematics of Tongji University are generally aimed at mathematics and economic students. If you want to take the postgraduate entrance examination in the department of mathematics, you must use the textbook of Mathematics One and Mathematics One. If you are a graduate student in the Department of Mathematics, you must be in the Department of Mathematics.
Compared with Math One and Math Three, there are many more things. There are many things that mathematics needs to know, and mathematics needs to be mastered and applied. For example, triple integral mathematics three is not involved, but mathematics one must be learned. Another example is Taylor's formula. As long as it can be expanded in Math III, there is no need to discuss the form of R(n), but Math I must be able to use several different residuals. For another example, in Math III, Fourier series is not tested. Even if the test is very simple, in Math I, Fourier series is very important. Wait, I won't give examples one by one.
Why not? You have to go to the math department to buy it.
PS: Be sure to read the outline and review it accordingly.
