Basically, every major in the university will learn a course called advanced mathematics, which is divided into two volumes, but in general, it is a subject calculus. When you take the postgraduate exam, you may know that the real exam of calculus may be much more difficult than your science, because later you find that the difficulty of your science math exam is really equivalent to the entry level, that is, you don't need to master any operation skills. As long as you know the basic theorem, you can calculate the answer casually, but the postgraduate mathematics is definitely not that simple, so calculus is a big problem. It can be said that calculus is the most difficult part of postgraduate mathematics, and the latter two subjects are easy to do.
Sometimes the university canteen is funny to do some formulas, such as calculus. In fact, it has fixed simplification rules. If you want to solve integrals, such as one yuan, two yuan, one fold and two fold, the most basic, you should know some simplification methods, such as infinitesimal substitution, such as L'H?pital's law, such as its formula. These are the most basic things, and then it comes to the reverse order of integrals.
And I have to mention that not all hematology majors learn advanced mathematics, and some majors don't learn mathematics. For example, medicine has a friend who is studying medicine. Even if he doesn't study math, he won't take this test in the postgraduate entrance examination. There are also professional masters who generally don't take math exams, so it's getting harder and harder to take politics exams in professional courses. Calculus is not as helpful to real life as you think, but it is something to think about.
