The Best App that can do any math problem
App that can do any math problem can be a useful tool for these scholars. Many linear algebra books think that it is more suitable for computers to solve the inverse of a matrix, because it involves less algebraic operations, but it may not be effective for matrices in 3D. Cramer's rule is a method for solving linear equations. The solution of the unknown in the i-th column is the determinant of the replacement matrix generated by replacing the i-th column of the coefficient matrix with the constant column, divided by the number obtained by the determinant of the original matrix. In the operation of matrix data, STL or a third-party library are generally not used, but data pointers are directly used.
Compared with the traditional CFD method, which needs to solve the complex second-order nonlinear N-S equation, the Boltzmann equation solved by LBM is a simple linear equation, and its mathematical processing is much simpler. In addition, LBM shows propulsion in the time domain based on the statistical distribution of particles, which is completely different from the traditional CFD Euler method based on implicit iteration. Zhang Chaoyang first reviewed the power series solution of Legendre equation with netizens, and explained under what circumstances the power series solution can bring convenience to the solution process. For this homogeneous linear equation, if the recurrence relationship of the coefficients obtained after substituting the solution in the form of power series is only related to two coefficients, it will be easy to get the growth of the coefficients, so that it is easy to analyze the boundary behavior of the solution; If the obtained coefficient recurrence relationship is related to multiple coefficients, it is difficult to know the changes of the coefficients. The exploration of quantum computing for scientific computing can start with HHL quantum algorithm.
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.
There are more than three solutions to any problem. Let's have a parent-child brainstorming to explore a variety of possibilities. Thank you for the emergence of this problem, which gives us the opportunity to learn new solutions to the same type of problems. So, how to judge whether the problem-solving list made by parents and children is really helpful to children? Positive discipline puts forward four elements for solving problems: It is a great wisdom of parents to calm down before solving problems. In the face of the grinding behavior of children in the rebellious period, we should first deal with our emotions and then solve problems.
