Obviously, this equation is a univariate quadratic equation that we learned in junior high school, which is called the characteristic equation of differential equations here. So we transform a more complex second-order homogeneous linear differential equation with constant coefficients into a simpler one-dimensional quadratic equation, which has exactly two roots. One of the problems often encountered in mathematics is the solution of equations, especially in linear algebra. Today, we will use matlab to explore the solution of linear equations. There are still a few differential equations that can be solved strictly, but many differential equations, including partial differential equations, can be approximated by series solutions. So using series to approximate function is an important part of calculus. Many differential equations can be solved by integrating directly, but some differential equations are not. In other words, it is difficult to find suitable differential homeomorphisms directly for these differential equations to rectify the original equations. For this reason, Newton thought of using Taylor expansion to solve it. The general idea is as follows: Differential equations are developed along with calculus. Newton and Leibniz, the founders of calculus, have dealt with problems related to differential equations in their works. Differential equations are widely used and can solve many problems related to derivatives. In physics, many kinematics and dynamics problems involving variable forces, such as the falling body motion with air resistance as a function of speed, can be solved by differential equations. In addition, differential equations have applications in chemistry, engineering, economics and demography. When using numerical methods to solve the governing equations, we always try to discretize the governing equations in the space domain, and then solve the resulting discrete equations. In order to discretize the governing equations in the spatial domain, grids must be used. A variety of methods for discretizing various regions to generate grids have been developed, collectively known as grid generation technology. The production process of grid is the coordinate mapping process from computing plane to physical plane. Explain the neural network as a discrete format for solving differential equations? The field of numerical solution will pay attention to the numerical convergence of discrete schemes, but what is the connection between this and differential equations? How to map the input-output mapping of the network connection to the infinite dimensional mapping of differential equations? Using the knowledge of dynamic system to analyze the properties of neural network? As a numerical analysis method, the whole solution process of finite element method is completely different from those classical analytical methods in solving mathematical and physical equations. The following table lists the differences between the mechanical analytical solution and the finite element method. While the function represents the change of state, the differential equation studies the relationship between the change of state and its change field. Since we regard the state to be solved as an arbitrary state, the final differential equation actually replaces the whole by studying the tiny local area. We think that as long as the local area is solved, it can be directly extended to the whole or the whole through recursion, so recursion is the essential idea of global solution. In practical application, many problems are quite complex, and the differential equations constructed are also extremely complex. It is impossible to get the expression of y = f (x). Fortunately, many problems do not need to solve the expression, only the value of y can be calculated. Since Newton, many mathematicians have studied the numerical solution methods of differential equations. Let y = UX be converted into a differential equation with separable variables for solution. For a first-order ordinary differential equation, if every function y except the first derivative term is the same as the power of X of the independent variable, it is called a homogeneous equation. Note: the homogeneous here means that the function y is the same as the power of the independent variable x. ① Clem's law There are two preconditions for solving the equations with Clem's law, one is that the number of equations should be equal to the number of unknowns, and the other is that the determinant of the coefficient matrix should not be equal to zero. Solving equations with cram's rule is actually equivalent to solving linear equations with the inverse matrix method, which establishes the relationship between the solution of linear equations and its coefficients and constants. However, since n + 1 n-order determinants need to be calculated when solving, the workload is often very large, so cram's rule is often used in theoretical proof and rarely used for specific solutions. For the 3D problem, its essence is to solve the elastic mechanics problem with 6 independent stress components (shear stress is equal to each other), 6 independent strain components and 3 displacement components. This problem can be solved by simultaneous equilibrium equations (3), geometric equations (6) and physical equations (generalized Hooke's law, 6). The relevant equations are shown in the figure below, which include inertial force for analyzing dynamic problems. These two problems should be very natural when we learn to solve differential equations, especially for high school students. In addition, there is no complete proof in furthermath's book, but only a numerical example. So here is an explanation for your learning and understanding. I personally feel that this method of deep learning is more suitable for solving scenarios where people are difficult to model with mathematical and physical equations and do not have high accuracy requirements, so it has a taste of compromise. Many scenarios in the real physical world have been abstracted into groups of equations and many laws. Solving equations directly is the most convenient way to get satisfactory answers. Second: the knowledge of higher numbers used in Electrotechnics is derivative, differential, integral, and differential equation. Here, solving differential equations is the focus. Because when we learn about capacitance and inductance, their expressions are solved by differential equations. Lagrange found that this method is general, that is, for any equation, this process is deterministic, rather than free to evaluate and prove like the predecessors So he applied it to the solution of the quintic equation, but at this time he encountered the same trouble as the final one in the previous section: unlike the quadratic, cubic and quartic equations, the number of presolutions constructed can be one lower than the number of equations to be solved, and the solution of the presolutions constructed by solving the quintic equation will eventually be the sixth equation! So it can't be solved recursively Similar to the solution of ordinary differential equations, we can first find the general solution of the above partial differential equations; In addition, in order to obtain a unique and definite reasonable solution, we also need definite solution conditions. Since u is a function of position and time, we can intuitively understand that the definite solution conditions include initial conditions and boundary conditions, that is, the physical state at the initial time t = 0 and the boundary condition of the whole physical process (because the boundary state will affect the whole region studied point by point through the continuum).
