Abstract

In this thesis, a novel wavelet method is successfully used to find the numerical solution to the Burger's Fisher problem. This strategy exhibits reasonably rapid convergence when compared to other strategies currently in use. Examples are given as illustrations to show how the new wavelet method works and how strong it is. By comparing the results, finding the precise solution, and using the numerical output from the cas wavelet and the haar wavelet, we were able to develop the general formulas for n different wavelet integrals

Keywords
