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. solution, most de’s have inﬁnitely many solutions. For example, the differential equation needs a general solution of a function or series of functions (a general solution has a constant “c” at the end of the equation): Related Differential Equations News on Phys.org. 7. When a differential equation specifies an initial condition, the equation is called an initial value problem.Initial conditions require you to search for a particular (specific) solution for a differential equation.
