What are the scores of compulsory one to five and elective courses in senior high school mathematics? (Tianjin) Which part of the college entrance examination is important?

It's hard to say that the required courses of high school mathematics 1 to 5 and the elective courses each account for this. Let me talk about specific knowledge points.

Sequence 5+ 12

1, select or fill in the blanks.

Test a simple sum or a project

2. Short answer (there is a complete opportunity to complete it)

Proof (arithmetic progression or geometric progression)

Find the general formula (construction method, definition method, etc.). ), summation (general test dislocation subtraction), proving inequality

Triangle 5+ 12

1, select or fill in the blanks.

The test is relatively simple (test images, properties, telescopic transformation (generally in the second question), basic properties, inductive formula, trigonometric solution)

2. Short answer (impossible ending)

Generally, it is the first big question.

The first problem to find f(x) is simplified by the knowledge of double angle formula.

The triangle part requires simplification of asinx+bcosx, accounting for 12.

y=asinx+bcosx

=√(a？ +b？ )【sinx*a/√(a？ +b？ )+cosx*b/√(a？ +b？ )]

Let cosφ=a/√(a? +b？ )

So sinφ=√( 1-cos? φ)=b/√(a？ +b？ )

So the original formula =√(a? +b？ )(sinxcosφ+cosxsinφ)

The second problem is monotonicity, maximum, range, period, telescopic transformation and so on.

Space geometry 5+ 12

1, select or fill in the blanks.

Calculate the distance or relationship between a straight line and a plane (judge right or wrong)

2. Short answer (impossible ending)

Syndrome is parallel or vertical.

Find dihedral angle, find distance

Function 5+5+5+ 12 (inequality application)

1, 3 Select or fill in the blanks.

Check the image, find the domain, and combine with inequality, and it will be established.

2, short answer (may be the finale)

Derivation, monotonicity, extreme value, inequality proof, constant establishment, discussion of quadratic function root

Analytic geometry 12+5 (linear programming) +5 (equations of lines and circles) +5

1, 3 Select or fill in the blanks.

Linear programming, equations of straight lines and circles, elliptic hyperbola, equations, parameters, distances, etc.

2, short answer (can be the finale)

Nothing more than a circle, an ellipse, a hyperbola or a parabola. (Find the slope, find the length of the line segment, find the standard equations, evaluation domain, existing problems and so on. There are many variations, sometimes involving vectors. I think it is more difficult.

Program block diagram 5

Do a multiple-choice question

Probability 12+5

1, select or fill in the blanks.

Finding the probability is relatively simple.

2. Short answer (not the finale)

Test probability, test variance and expected value

Necessary and sufficient conditions 5

Choose or fill in the blanks.

This is not easy to do.

Complex number 5

A choice, the simplification of complex numbers
