1. Common logical terms

(About 8 class hours) (1) Proposition and its relationship ① Understand the inverse proposition, negative proposition and negative proposition of a proposition. ② Understand the meanings of necessary conditions, sufficient conditions and necessary and sufficient conditions, and analyze the relationship among the four propositions. (2) Simple logical connectives understand the meaning of logical connectives "or" and "not". (3) Full-name quantifiers and existential quantifiers ① Understand the meanings of full-name quantifiers and existential quantifiers. ② Propositions containing quantifiers can be correctly denied.

2. Conic curves and equations

(about 16 class hours) (1) conic curve ① Understand the actual background of conic curve and feel the role of conic curve in depicting the real world and solving practical problems. ② Experience the process of abstracting ellipse and parabola models from specific situations, and master their definitions, standard equations, geometric figures and simple properties. ③ Understand the definition, geometry and standard equation of hyperbola, and know the related properties of hyperbola. ④ Coordinate method can be used to solve some simple geometric problems (the positional relationship between straight lines and conic curves) and practical problems related to conic curves. ⑤ Through the study of conic curve, we can further understand the idea of combining numbers with shapes. (2) Curve and equation Understand the corresponding relationship between curve and equation, and further feel the basic idea of combining numbers and shapes. (3) Elliptic standard equation x2/a2+y2/b2 of ellipse, hyperbola and parabola =1(a > b >; 0, c 2 = a 2-b 2) (focus on the x axis) focus F 1(-c, 0), eccentricity of F2(c, 0) e=c/a hyperbolic standard equation X 2/A 2-Y 2/B 2 = 65432. 0, b>0, c 2 = a 2+b 2) (focus on x axis) focus F 1(-c, 0), eccentricity of F2(c, 0) e=c/a parabola standard equation y 2 = 2px (p > 0) (focus is on the positive semi-axis of X axis) Focus F (p/2,0)

3. Space vector and solid geometry

(about 12 class hour) (1) space vector and its operation (2) application of space vector
