Hope there are experts who can help you!

The accounting postgraduate examination is divided into accounting master's degree and accounting master's degree, which are collectively referred to as accounting postgraduate examination, but the mathematical content to be tested is different.

The mathematics in the accounting master's degree is in the joint entrance examination, which is what we call the 199 management joint examination.

The mathematics tested in the 199 management joint examination belongs to basic mathematics, and the content of the test is the mathematics knowledge learned in high school, which is very simple.

The Master of Accounting is what we often call accounting, and the accounting test is mathematics III.

Postgraduate Mathematics III is a test of advanced mathematics, linear algebra, probability theory and mathematical statistics.

Mathematics III has a full score of 150 points, and from the perspective of the structure of the test paper, there are three types of questions: multiple-choice questions (8 questions with a total of 32 points), fill-in-the-blank questions (6 questions with a total of 24 points), and solution questions (9 questions with a total of 94 points). By analyzing the test points given in the exam syllabus in recent years, the third number requires 173 test points, and the basic knowledge will account for 70% of the total score, that is, 150*70%=105 points.

At the same time, there will also be a focus, and the number three requires mastery of economic application issues.

Postgraduate Mathematics First Exam:

High linear algebra.

Probability theory, mathematical statistics.

1. Functions, Limits, and Continuities (1) Changes in the content of the exam New knowledge points:

Someone who has come over suggests that you must take a good look at the past questions, which is the most useful, especially in recent years; That's how everyone crossed the river by feeling the stones.

High math, line algebra probability is mainly these three parts, you have to buy this book, specifically look at the chapters and knowledge points of the test, Chen Wendeng and Li Yongle's books are OK

Ah, how many math questions are taken in the math graduate school entrance examination.

All exams... Mathematics 1 content is to be fully examined. High numbers, line algebra probability.

bars 52, running water is not rotten, the hub is not beetle, and the people's livelihood is diligent. In the era of information flying all over the sky, full of doubts, I found the ideal course, Gong Zhong search: "Seven Steps Online Course".

..Let's talk about my postgraduate entrance examination experience, I had a sense of crisis in my junior year, and I wanted to improve myself, so I made up my mind to go to graduate school, but at that time, I knew that my self-control was not very good, there was no teacher in the university who would care about you, many classmates were getting by, and I was no exception, I almost didn't settle down to study hard, and I didn't go to the library a few times.

The key is stubble, the key is the key

There are three courses, high number line algebra and probability, but the focus of the exam is different from the courses in the university, and it needs to be studied in a targeted manner. At present, the Hebei Middle School Congregation Enjoyment Course is especially suitable for students who are admitted to graduate school in mathematics, and it is recommended to connect.

f(x) is a function with x as an independent variable.

Derivative, also known as derivative value. Also known as micro-quotient, it is an important basic concept in calculus. When the independent variable x of the function y=f(x) produces an incremental δx at a point x0, the ratio of the incremental δy of the output value of the function to the incremental δx of the independent variable is at the limit a when δx approaches 0 if it exists, a is the derivative at x0 and is denoted as f'(x0) or df(x0) dx.

f(x) is a function with x as an independent variable.

Given a set of numbers a, suppose the element in it is x. Now apply the corresponding rule f to the element x in a, denoted as f(x), to get another set b. Suppose the element in b is y. Then the equivalence relationship between y and x can be expressed by y=f(x).

For example, y=x can also be written as f(x)=x, which means the same.

f(a)=0, which means that in the function f(x), when x=a, the function value is 0.

A function is a correspondence that occurs between sets. Then, it is necessary to understand that there is more than one function relationship between a and b. Finally, it is important to understand the three elements of a function.

The correspondence of functions is usually expressed in analytical, but a large number of functional relations cannot be expressed analytically, and can be expressed in images, ** and other forms.

In a process of change, the amount of change is called a variable (in mathematics, it is often x, and y changes with the change of x value), and some values do not change with the variable, we call them constants.

Independent variable (function): A variable that is associated with a quantity, and any value of this quantity can find a fixed value in its quantity.

Dependent variable (function): When the independent variable changes and the independent variable takes a unique value, the dependent variable (function) has and only a unique value corresponding to it.

Function value: In a function where y is x, x determines a value, y determines a value, and when x takes a, y is determined as b, and b is called the function value of a.

From a {2}, the solution is b=-3, c=4, and the result comes out when it is brought in, it is 3 2, he is x 2-6x+7=0 to solve it, embarrassed ......

f stands for functions,functions is the meaning of function,The concept of function is actually very broad,Basically, anything in our world can be described or represented by a function,To give you an example,For example, the market of TV** and your desire to buy can form a functional relationship,**low your desire to buy is high,**high your desire to buy is low,so**with your desire to buy can be expressed by a function。 Later you will learn the philosophical concept that things are universally connected, and functions are used to express specific relationships between things that are universally connected.

f(x) in x is an independent variable, as the name suggests, it refers to the amount that does not depend on other things to change as much as you want, it contains more active meaning, f(x) represents the meaning of change because x changes with change, so it is called dependent variable. f represents how f(x) changes with x.

To give some examples of the properties of the function: f(x) = 3x + 2 x on the right side of the equation and the x in f(x) parentheses mean the same thing. If f(x-1) = 3x + 2, then f(x-1) = 3(x-1) + 5, so f(x) = 3x+5, whether it is a hidden function or an explicit function, as long as the amount in parentheses is the independent variable can be solved, in addition, the function must be looked at with the thinking of change, the function is not static, it contains various meanings of change, including the range of change, the way of change, etc.

f(x) is actually a function symbol that represents a function related to x.

For example, we used y=3x+2 to express the relationship between x and y, x is the independent variable, y is the dependent variable, and y is a function of x;

Now use f(x) instead of y, and the one just now can be expressed as f(x)=3x+2, and the relationship is exactly the same. It's just more important that this is a function and is related to the independent variable x.

This expression with f(x) mainly started in high school, at that time there were many chapters dedicated to functions, the introduction of the concept of functions is generally about mapping, but also a relationship between quantities, and f generally represents the mapping method, f(x) represents the quantity obtained by x after mapping f, if the mapping method is 3x+2, then the quantity f(x) is y.

In a word, just use f(x) as a symbol.

I don't know how to explain it scientifically, but I can only say that I understand it.

f(x) is an evolved expression of y, and f(x) and y have the same meaning, but there is an extra x to express.

When y=2x+3.

f（x）=2x+3

f(1)=2×1+3=5

f(2)=2×2+3=7

f(3)=2×3+3=9

f(n)=2×n+3=…

Solution: From f(x) x, we get f(x)-x=0, that is, x 2+(b-1)x+c=0

From a {2}, we can get the solution of the above equation only x=2, and substitute it to get 4+2(b-1)+c=0 (1) and discriminant formula to get the tower = (b-1) 2-4c=0 (2) solution (1) (2) of the system of simultaneous equations, to get b=-3 and c=4, i.e., f(x)=x 2-3x+4

From f(x-1) x+1 there is (x-1) 2-3(x-1)+4=x+1 to obtain x=-1 or x=7

So the set b=

P.S. f(x) represents a function with a variable of x.

I won't say much more.

I'll help you solve the problem.

f(x) x squared + bx + c = x 2 + bx + ca {x|f(x) x}, and a {2}

Explain that the equation f(x) x has a unique solution x=2

x 2 + bx + c = x has a unique solution x = 2

x^2+(b-1)x+c=0

Then discriminant (b-1) 2-4c=0 4c=（b-1)^2 (1)

and 4+2(b-1)+c=0, 2+2b+c=0, 8+8b+4c=0 (2).

1) Generations (2).

b-1)^2+8+8b=0

b^2+6b+9=0

b=-3 ,c=4

Then f(x)=x 2+bx+c=x 2-3x+4f(x-1)=(x-1) 2-3(x-1)+4=x 2-5x+8 pairs bf(x-1) x+1

then x 2-5x+8=x+1

x^2-6x+7=0

x=3±√2

f stands for functions, which means function.

x is the independent variable, f(x) is the dependent variable, that is, the equation with x as an unknown quantity changes with x, and f(x) also changes.

Each x corresponds to a value of f(x) (the value of f(x) can be equal) e.g., f(x) = 2x, f(x) = x 2 (square of x), and so on.
