1, trigonometric function:

There are two ways to test trigonometric functions. They are the solutions of triangles and trigonometric functions themselves. About 10% to 20% probability to solve the triangle, 80% to 90% probability to skillfully use the trigonometric function itself.

2, probability statistics:

Taking science mathematics as an example, the test center covers the compulsory and optional chapters of probability statistics, and examines the basic knowledge such as sampling method, statistical chart, digital characteristics of data, estimating the whole with samples, regression analysis, independence test, classical probability, geometric probability, conditional probability, probability of independent repeated trials, distribution list of discrete random variables, mathematical expectation and variance, hypergeometric distribution, binomial distribution and normal distribution.

3, solid geometry:

There are two or three problems with this question. The first problem is the size of a line or the proof that a line or a surface is parallel or perpendicular to another line or another surface. The last question is to find the dihedral angle.

4. Series:

The sequence is mainly to solve the sum of the general term formula and the first n terms. The first is the general formula, which depends on the conditional form given in the title. Different forms correspond to different problem-solving methods, including formula method, accumulation method, accumulation method, undetermined coefficient method, mathematical induction method, reciprocal change method and so on. Skillfully use these methods, accumulate examples and achieve proficiency.

5. Conic curve:

The general routine is that the first half is the investigation of basic properties, the second half is the intersection of straight lines, and the steps in the second half are similar.
