1, high school mathematics has nothing to do with junior high school mathematics. As long as you have the basic operation ability of addition, subtraction, multiplication and division and the thinking ability of classified discussion, you can supplement the basic knowledge of linear function, quadratic function, inverse proportional function and special trigonometric function values. Like the similarity in junior high school, round knowledge and moving questions are basically not needed in senior high school.

So we should have confidence to learn high school mathematics well.

2. The first unit set of high school mathematics is new knowledge, and the monotonicity and parity of the second unit function are also new knowledge. The third unit exponential function and power function are related to junior high school power operation; Logarithmic functions are also new.

Junior high school uses compulsory trigonometric function, and plane vector is also a new content.

To sum up, high school mathematics has little to do with junior high school.

3. how to learn?

(1) It is suggested to review the contents of trigonometric functions and understand the three basic images well. Understanding and applying formulas of trigonometric functions. Preview the required five solutions to the triangle.

(2) Review several multiplication formulas, skillfully use the formulas to find the maximum value, and preview the required 5 series and inequalities.
