Compulsory 1: the relationship between set and set representation and the monotonicity of operation function representation, the image and properties of odd linear function and the application of image and properties of quadratic function. The approximate solution of function zero is calculated by exponential power of real number and logarithmic function of operation exponential function. The application of power function is compulsory 2: the relationship between points, lines and surfaces in space geometry. Equation of the circle of plane analytic geometry compulsory 3: algorithm and program block diagram in the basic algorithm statement. In ancient mathematics in China, the random sampling of algorithm cases is to estimate the related events and probability of population variables with samples. The meaning and application of classical probabilistic random numbers are compulsory. 4. The concept and radian of trigonometric function with arbitrary angle. Analysis of linear motion vector and attribute vector of image and coordinate operation of vector. Application of quantitative product vector of plane vector and multiplication of angle formula, double angle formula, half angle formula and trigonometric function. Sum, difference, sum and product of difference must be five: positive and mysterious theorem, cosine theorem, recursive formula of triangle area series, etc. Arithmetic progression's conceptual nature and application geometric progression's conceptual nature and the application of inequality are all inequalities, and the practical application of solving inequality is a simple linear programming of plane area expressed by quadratic inequality in one variable.
