To provide enough information and tips so that users can pose problems to DSolve in the most appropriate form and apply the solutions in their work.For this reason, these tutorials have the following basic goals. ![]() The process described is done internally and does not require any intervention from the user. For example, higher-order ODEs are typically solved by reducing their order to 1 or 2. The code has a hierarchical structure whereby the solution of complex problems is reduced to the solution of relatively simpler problems, for which a greater variety of methods is available. Once a problem has been classified (as described in "Classification of Differential Equations"), the available methods for that class are tried in a specific sequence until a solution is obtained. The design of DSolve is modular: the algorithms for different classes of problems work independently of one another. Goals of Differential Equation Solving with DSolve Tutorials As with PDEs, it is difficult to find exact solutions to DAEs, but DSolve can solve many examples of such systems that occur in applications. Differential-Algebraic Equations (DAEs), in which some members of the system are differential equations and the others are purely algebraic, having no derivatives in them.Finding exact symbolic solutions of PDEs is a difficult problem, but DSolve can solve most first-order PDEs and a limited number of the second-order PDEs found in standard reference books. Partial Differential Equations (PDEs), in which there are two or more independent variables and one dependent variable.DSolve is equipped with a wide variety of techniques for solving single ODEs as well as systems of ODEs. Ordinary Differential Equations (ODEs), in which there is a single independent variable and one or more dependent variables.(The Wolfram Language function NDSolve, on the other hand, is a general numerical differential equation solver.) DSolve can handle the following types of equations: The Wolfram Language function DSolve finds symbolic solutions to differential equations.
