1, establish equations or equations and solve them. There are too many examples, such as the sports part in the required exam 1, which will be involved.

2. The application of function, the function image is often used to analyze physical problems, and the function formula is also often used to solve the maximum problem. The latter appears in the third year of high school, but it is generally not involved in the first year of high school.

3. Plane geometry and trigonometric functions. Commonly used are Pythagorean theorem, parallelogram angle relation, and some properties of a circle (central angle, vertical relation between tangent and radius, etc.). ), sine cosine, tangent trigonometric function, sine cosine theorem.

4. Plane vector, mainly applied to vectors. This is generally not the focus of mathematics application, because high school physics generally does not discuss real vector operation, but usually converts vector operation into number operation.

5, limit, this expansion in college is calculus, but it will not be involved in high school, just a popular mention. Because the operation of differential depends on advanced mathematics, it is beyond the scope of high school mathematics.
