1. Functions and equations: including the definition, properties, images and analytical expressions of functions, as well as quadratic equations and inequalities. These knowledge points are the foundation of high school mathematics and need to be mastered skillfully.
2. Number sequence and mathematical induction: Number sequence is an important content in high school mathematics, including arithmetic progression, geometric progression and recursive number sequence. Mathematical induction is a common method to prove the nature of sequence, and it is also one of the high-frequency test sites.
3. Trigonometric function: including the definition, properties, images and analytical expressions of trigonometric function, as well as the basic formulas and identities of trigonometric function. These knowledge points are often used in solving geometric and physical problems.
4. Plane vector: including the definition, operation, product and cross product of vector. Vector is often used to solve geometric problems and physical problems, so it is one of the high-frequency test sites.
5. Probability and statistics: including the definition, nature and calculation method of probability, as well as the basic concepts and methods of statistics. These knowledge points are often used in solving practical problems, so they are also one of the high-frequency test sites.
6. Derivative and differential: including the definition, properties and calculation methods of derivative, as well as the concept and application of differential. Derivative and differential are often used to solve the extreme and maximum values of functions, so they are also one of the high-frequency test sites.
7. Spatial geometry: including the positional relationship of points, lines and surfaces, as well as the properties and calculation methods of spatial graphics. Space geometry is often used in solving solid geometry problems, so it is also one of the high-frequency test sites.
The above are some high-frequency test sites in high school mathematics, and mastering these knowledge points is very important for improving mathematics scores. At the same time, we should consolidate and apply these knowledge points through a lot of exercises to improve our problem-solving ability.
