The review of mathematical derivatives in Guangxi Adult College Entrance Examination focuses on: ① Finding the derivatives of several common polynomial functions.
② Use the geometric meaning of derivative to find the tangent equation of curve, and use derivative as a tool to find the monotonous interval, extreme value, maximum value or minimum value of function.
③ Solve simple practical application problems and find the maximum or minimum value.
Triangle part: On the basis of understanding trigonometric functions and related concepts, master the transformation of trigonometric functions, including the basic relationship between trigonometric functions with the same angle, the inductive formula of trigonometric functions, the formula of trigonometric functions with two angles and their differences, and the sine, cosine and tangent formulas of double angles, and calculate and simplify them with formulas.
Plane analytic geometry: Analytic geometry studies geometric problems by algebraic methods through coordinate systems and equations of straight lines and conic curves. In the chapter of plane vector, on the basis of understanding vectors and related concepts, we focus on the algorithm of vectors and the necessary and sufficient conditions for vectors to be vertical and parallel. The review of the straight line chapter focuses on the inclination angle and slope of the straight line, the five forms of the straight line equation and the positional relationship between the two straight lines.
Solid geometry part: In recent years, the requirements of the examination syllabus for this part have been significantly reduced. The focus of the investigation is on the various positional relationships between straight lines, straight lines and planes, and planes and planes, as well as the basic knowledge of the calculation of the surface area and volume of prisms, pyramids and spheres.
In the chapter of probability statistics: permutation and combination, we should pay attention to the main differences between the principle of classified counting and the principle of step-by-step counting, and remember the calculation formula of permutation or combination number, which will solve simple practical problems about permutation or combination.
