چکیده
|
The present paper presents the comparison of analytical tech-niques. we establish the existence of the phenomena of the noise terms in the perturbation series solution and find the exact solution of the nonlin-ear problems. if the noise terms exist,the homotopy perturbation method gives the same series solution as in adomian decomposition method and we get the exact solution using two iterations only.
