We also, study the numerical stability by Fourier (Von-Neumann) method for the two scheme which used in the solution on all mesh points to ensure the stability of the point which had been treated in the suggested style, we using two interval with two initial condition and the numerical results obtained by using these schemes are compare with Exact Solution of Equation Excellent approximate is found between the Exact Solution and numerical Solutions of these methods. 2024 19 26 3217 https://creativecommons.org/licenses/by/4.0/ 10.54216/NIF.040204 https://americaspg.com/journal/39/article/3217 https://americaspg.com/storage/articles/manuscripts/01M3R15S5C10HNHSPZP0ZNK0M2.pdf
