2. Solid geometry (space geometry is solid geometry), plane analytic geometry (straight lines, circles, equations, key and difficult points in the college entrance examination, the questions will be very lively! )

3. Algorithm, statistics, probability (this book is relatively simple, almost filling in the blanks in the college entrance examination)

4. trigonometric functions (sinx cosx images, etc. ), plane vector, trigonometric identity transformation (many formulas).

5. Solve triangles, sequences and inequalities

I hope it helps you! Generally speaking, high school mathematics is more systematic and easier to learn than junior high school mathematics, and it is by going up one flight of stairs than junior high school mathematics!
