What are the questions that are often tested in mathematics?

At most, it should be a quadratic function, I'm talking about middle school!

Scope of the Senior Secondary Mathematics Examination: The content of the five modules of compulsory "Mathematics 1" to "Mathematics 5" stipulated in the General High School Mathematics Curriculum Standards (Experimental). The details are as follows:

1. Sets and Simple Logic Imaginary Jujubes.

1. There are 2" subsets of a set of n elements.

2. Characteristics of collective elements: certainty, disorder, and mutual heterogeneity.

3. The operation of sets: intersection, union, and complement.

4. Common logical terms: or, and, not: sufficient and necessary conditions.

2. Functions. 1. Define domains, value ranges, analytic formulas and properties.

2. Piecewise functions.

3. Exponents. 4. Logarithms: (1) Negative numbers and zeros have no logarithms; (2) The logarithm of 1 is equal to 0; (3) The logarithm of the base is equal to 1; (4) The logarithm of the product, the logarithm of the quotient, and the logarithm of the power.

3. Sequences. 1. The sum of the first n terms of the series; The first n terms of the number series and their relationship to the general terms.

2. Equal difference series, general term formula, first n term and, equal difference middle term.

3. Proportional series, general term formula, first n terms, and proportional middle terms.

4. General method.

4. Trigonometric functions.

1. Radian system.

2. Trigonometric functions, trigonometric values of special hunger angles, and basic relations of trigonometric functions at the same angle.

3. The sine, cosine, tangent, auxiliary angle formula, double angle formula, and solution triangle of the sum and difference of the two angles.

4. Induction formula: sine is positive; The right side of the cosine is positive; Tangent one three is positive.

5. Plane vectors.

1. Coordinate operation is returned.

2. Important conclusions.

6. Inequality.

1. Mean inequality.

2. Methods for solving exponential and logarithmic inequalities.

There are usually big questions in the mathematics exam. Different provinces have different situations, and the proportion and score of the big stool questions are also different.

The grade results of the mathematics test of the HKCEE are ranked from high to low: A, B, C, D, and E. The proportion of the number of people in each grade is as follows: 15 for grade A, 30 for grade B, 30 for grade C, and 25 for grade D and E (including 0 points, the same below).

Grade E is unqualified.

The cultural subjects of the high school diploma examination are held twice a year, and the first time is arranged around January, of which the three subjects of Chinese, mathematics and foreign language are mainly for senior high school candidates, and the other subjects are mainly for senior high school students; The second time is arranged around June, and the six subjects of ideology and politics, physics, chemistry, biology, history, geography, etc., are mainly for sophomore high school candidates.

If candidates do not participate in the spring college entrance examination, they may not take the qualification examination for Chinese, mathematics and English subjects; More than 98% of the total number of candidates in Chinese, mathematics and foreign language subjects in the unified college entrance examination can be regarded as passing the corresponding subject test results.

The above information refers to the encyclopedia - general examination.

Summary. Can you describe the problem in detail?

Can you describe the problem in detail?

Question 6: How to write it, brother.

Can you make the question clearer?

What now. Why are you so dizzy as soon as you read it?

A: 50+ years old.

According to the calculation, a 50-year-old man can live to be a good year. Look).

<> draw a diagram and find the number of vertical rows of an unknown family, and it will be solved. You can also look at the beams to see if there's an easier way.

Generational nature f(-x)=-f(x).

2 (-x)+b] [2 (2-x+2)+a]=-2 x+b] [2 (x+2)+a] is squared.

Multiply the top and bottom on the left by 2 x, and then the numerator and denominator on the left and right sides are equal.

a=4 b=1
