Methods of Obtaining Differential Equations
The paper explores various methods of defining differential equations by starting points of processes. Apart from the classical approach based on drawing up and the solving the system of linear equations, we use methods of modification of this system proceeding from the nature of the process. Modification of starting points additional functions, the use of additional links between coefficients in the system of the equations, as well as optimization of the obtained coefficients by other criteria of accuracy of the equation are proposed.
