What are some of the more difficult types of questions in the required math test for the college entrance exam?

There are some relatively difficult types of questions in the compulsory high school math test that require a high level of mathematical thinking and problem solving skills. The following are some of the more difficult types of questions:

1. Functions and equations: Functions and equations are an important part of high school mathematics, involving the properties of functions, images, and solutions to equations. Among them, the composite and inverse function of function, the most value problem of quadratic function, the image transformation of trigonometric function are more difficult to understand and master the knowledge points.

2. Series and mathematical induction: series is the basic content of high school mathematics, involving the equal-difference series, equal-ratio series, recursive series, etc.. And mathematical induction is a method of proof that requires candidates to have strong logical thinking and reasoning skills.

3. Probability and Statistics: Probability and statistics is an important part of high school mathematics, involving the calculation of probability, the probability of an event, and the probability distribution of random variables. Among them, binomial distribution, normal distribution, conditional probability, etc. are more difficult to understand and apply the knowledge points.

4. Analytic Geometry: Analytic geometry is an important part of high school mathematics, involving the relationship between the position of a straight line and a circle, and the relationship between the plane and space. Among them, the intersection of a straight line and a circle and the distance between a plane and space are difficult to understand and solve.

5. Derivatives and Differentials: Derivatives and differentials are an important part of high school mathematics, which involves the derivatives of functions, applications of derivatives, and so on. Among them, the calculation of derivatives, application problems of derivatives, etc. are more difficult to understand and solve the knowledge points.
