1. trigonometric function: trigonometric function is an important knowledge point in high school mathematics, involving concepts such as angle, radian and trigonometric ratio. By learning trigonometric functions, we can solve many problems related to triangles, such as solving angles and side lengths.
2. Series and progression: Series is a series of numbers arranged according to certain rules, while progression is the process of adding items in the series. By studying sequence and series, we can study the properties of sequence, summation formula and convergence of series.
3. Probability statistics: Probability statistics is another important knowledge point of high school mathematics, involving random events, probability calculation, sampling survey, etc. By studying probability statistics, we can understand the basic concepts of probability, calculation methods and how to use statistical methods to analyze data.
4. Plane geometry: Plane geometry is a discipline that studies the properties and relationships of figures such as points, lines and angles on a plane. By studying plane geometry, we can master the properties, judgment theorems and proof methods of various figures, and cultivate logical thinking and spatial imagination.
5. Analytic geometry: Analytic geometry is a subject that studies the relationship between points, lines, curves and other figures on the plane and the coordinate system. By studying analytic geometry, geometric problems can be transformed into algebraic problems to solve, and the efficiency and accuracy of solving problems can be improved.
