1, plane vector and trigonometric function, trigonometric transformation and its application, this part is the focus of the college entrance examination, but it is not difficult. It mainly produces some basic or intermediate problems.

2, probability statistics, this part is related to life, is an application problem.

3. Investigate the definition and properties of conic curve, trajectory equation problem, parameter problem, fixed point fixed value problem and range problem, and solve the problem through coordinate operation of points.

4. Investigate the related concepts of set operation and function, such as the definition domain, range, analytical formula, limit, continuity and derivative of function.

5. Prove parallelism or verticality, and find the angle and distance. This paper mainly investigates the familiarity and application of the theorem.
