Problem-solving skills of common mathematical problems in function synthesis of senior high school entrance examination
This kind of math problem for the senior high school entrance examination is to directly give the rectangular coordinate system and geometric figures to the candidates for the senior high school entrance examination. First, the analytic expression of the function is obtained, and then the figure is studied, and the coordinates of points or some properties of the figure are studied. The main method to find the analytic expression of known functions is the undetermined coefficient method, and the key is to find the coordinates of points, while the basic methods to find the coordinates of points are geometric method (graphic method) and algebraic method (analytical method).
Geometric synthesis problem
This kind of math problem for senior high school entrance examination is to assign geometric figures to the candidates for senior high school entrance examination, calculate according to the known conditions, and then move the moving point (or moving line segment), which will correspondingly produce changes in line segment and area, find the analytical formula of the corresponding (unknown) function, find the value range of the independent variables of the function, and finally explore and study according to the obtained functional relationship.
The problem-solving skills of multiple-choice mathematics in senior high school entrance examination are mainly to highlight the ability. Small problems are usually done in a small way. In addition to direct solution, we should also pay attention to clever solution. Students are good at using the methods of combination of numbers and shapes, special values, exclusion, verification, transformation, analysis and estimation when doing multiple-choice questions in mathematics for senior high school entrance examination. Once the thinking is clear, you will answer quickly. Don't dwell on one or two small problems. If you really don't have any ideas, you can get one first and make a mark. Even if you get "Meng", there is a 25% winning rate, so you can choose to do it later.
Solutions to Common Fill-in-the-blank Questions in Mathematics for Senior High School Entrance Examination Because there are similarities between Fill-in-the-blank Questions in Mathematics for Senior High School Entrance Examination and multiple-choice questions, we can use some problem-solving methods and strategies. Fill in the blanks in the senior high school entrance examination should be carefully calculated, and the expression results must be accurate in value and standardized in form, otherwise the previous efforts will be in vain, because there is no process in filling in the blanks.
