Abstract:
In this dissertation,three methods,which are homotopy perturbation method and variational iteration method and wavelet method are used for solving the Fokker Plnck equation. In the Varational Iteration Method by using the correct functioal of the differntial equation which has made by selectingthe appropriate initial approximation,by using recursion relation and that u = limn!1 un ’ve gained answer the question. In the Homotopy Perturbation Method,first introduced a homotopy,secondly, cosider the answer in series and gains limit this series and earned equation. Wavelets constitute a family offunctions constructed from dilation and translation of a single function called the mother
wavelet. Wavelet theory in applied mathematics is a relatively new events.math rich content and ability to use wavelets are so satisfied and confident that given the speed,engineers and members with diverse expertise drew to solve various problems with this theory.
