Answer: in a determinant, rows and columns have the same status, and the nature of a determinant always holds true for rows and columns If all the elements in a certain column of a determinant are multiplied by the same multiple, it is equal to multiplying this multiple by this column Multiply the elements of a certain column of a determinant by the same multiple and add them to the corresponding elements of another column. The determinant remains unchanged Answer: B [test point click] this question was examined in the second major question and the 14th minor question of the real question in April 2007. The main knowledge points examined are the conditions for homogeneous linear equations to have non-zero solutions. [key points] equations have non-zero solutions, so the coefficient determinant In linear algebra, determinants are related to the coefficients of equations and coefficient matrices. The system of equations is related to the augmented matrix, the rank of the augmented matrix, and the rank of the vector system.

Functions, equations and inequalities are closely related and mutually transformed. Using the idea of equations, we can solve the analytic formula of functions by the method of undetermined coefficients. By equivalently transforming functions into equations of curves, we can discuss the number of square roots (or the number of zero points of functions) with the help of the image of functions. Because functions and inequalities have close internal relations, inequality is often used as a tool to study the properties of functions, For example, to prove (discuss) the monotonicity of the function and discuss the maximum value of the rain number, when dealing with the problem of constant inequality, it is often necessary to use the constructor to convert the image or property of the function, so as to determine the range of relevant parameters. The mutual transformation between the function and the equation and inequality is not only manifested in the quadratic function and the one-dimensional quadratic equation and the one-dimensional quadratic inequality, that is, the three ones, but also in the exponential function, Logarithmic functions, exponential and logarithmic equations, and exponential and logarithmic inequalities are mainly manifested in the following four aspects in solving problems.

It is difficult to win awards and the winning rate is low. It is difficult to improve in a short time. In order to meet the needs of students for the preparation of the competition, the micro store of digital modeling paradise has been officially launched. At present, more than 40 kinds of products related to mathematical modeling have been put on the store: including the explanation of real problems of the national competition, super excellent papers, summary of necessary models, tutorials of commonly used mathematical modeling software The preparation package for the National Games and other preparation materials are available.

This is what Dad wants to explain to you. 1. Start to prepare for the postgraduate entrance examination early, so that there is still enough time after class. Math and English can start reciting English words and reading the review book in the first semester of junior high school.

It often needs to be converted into area sum or area difference by means of cut and complement method, or by equal product transformation. Summary: as can be seen from the above examples, there are various areas of the shadow part of the circle, and there are also many ways to solve it. However, as long as the shadow in the thinking is removed through appropriate transformation and flexible processing according to the characteristics of the figure, it will certainly bring a bright future to the solution of the problem. Finally, I will improve the content of this part, using the characteristics of the coordinate system to solve the area of relevant graphics, and the specific graphics are proposed and solved by students themselves, so as to cultivate students' divergent thinking and feel the application of cut and fill here.

Amazing app, I've been using it for years and it works amazing. Solved every problem I couldn't and with their explanations I figured out how to solve similar problems. All in all, very useful and amazing app

This app is amazing! Has saved my stupid self a million times. Once I couldn't understand some question and I had a math paper that morning, I used this app and it told me the correct solution, it also explains everything step by step so that's really convenient! Overall, I'd say this app is really good! Totally worth the download!
