Form of particular solution to inhomogeneous differential equation. Unformatted text preview: Verifying Solutions to Differential Equations Verifying Solutions to Differential Equations To determine whether or not a given relation is the solution to a differential equation we can use substitution rather than solve the differential equation for the solution.To do this you will need expressions of any of the following that appear in the solution: , , , , . I can write a differential equation from a verbal statement about a function’s rate of change. See Example 1 . It only takes a minute to sign up. A solution to a differential equation is valid if it can be substituted into each side of the original equation and simplified to produce equal values on both sides of the equation. It also depends on whether or not the equations are nonlinear. Differential Equations. Solutions to this differential equation suggest that natural population growth is exponential. Solutions of this type are called analytic solutions. In the numerical solution of partial differential equations (PDEs) there has been a similar (although more advanced) effort in developing efficient numerical methods and corresponding verification tools for special classes of problems.
