Dear Anim, Can you provide an example to illustrate your question? As a first guess, I suggest you to check whether you supplied initial conditions. If they are specified, the constants within the homogenous solution will be solved for to match them. See below. Bye Ben (* no initial condition : homogenous solution *) DSolve[{x'[t]\[Equal]0}, x[t],t] Out[1]= {{x[t]\[Rule]C[1]}} (* initial condition : particular solution *) DSolve[{x'[t]\[Equal]0, x[0]\[Equal]0},x[t],t] Out[2]= {{x[t]\[Rule]0}} Tanim Islam schrieb: > Hi: > > I was wondering how to extract the homogenous solution (rather than the > exact or particular solution) when employing DSolve?
