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}}
