Moderately difficult math? Methods, MM, there are matrices, functions (various functions: linear, quadratic, cubic, inverse proportion, trigonometric function, inverse function), deformation of functions (that is, moving up and down, zooming in and out), normal distribution (which means a little statistical graph and is also the content of MF compulsory chapter), logarithmic one, exponential function, probability (the most annoying part of China students).
The most difficult advanced mathematics specialty? Mathematics, MS, imaginary numbers, vectors, vector functions, trigonometric functions, calculus, and many sports problems related to physics.
I have seen all three, and MF relies more on calculators; Well, I like it the least. This is a large number of questions, and it is very long, so it is difficult to read. MS is considered extremely difficult to learn by people here, but there is no child from China who doesn't learn MS, which definitely gives him extra points.
Attached are two pictures, MM and MS book catalogues, which are clear at a glance.
