Numerical solutions of a class of second order boundary value problems on using Bernoulli Polynomials
This is an incremental contribution for researchers working on numerical solutions of boundary value problems, offering an alternative approach with competitive accuracy.
This paper presents a method using Bernoulli polynomials as trial functions in a Galerkin weighted residual approach to solve second-order linear and nonlinear boundary value problems with various boundary conditions. The method achieves good accuracy compared to exact solutions and existing methods, as demonstrated through numerical examples.
The aim of this paper is to find the numerical solutions of the second order linear and nonlinear differential equations with Dirichlet, Neumann and Robin boundary conditions. We use the Bernoulli polynomials as linear combination to the approximate solutions of 2nd order boundary value problems. Here the Bernoulli polynomials over the interval [0, 1] are chosen as trial functions so that care has been taken to satisfy the corresponding homogeneous form of the Dirichlet boundary conditions in the Galerkin weighted residual method. In addition to that the given differential equation over arbitrary finite domain [a, b] and the boundary conditions are converted into its equivalent form over the interval [0, 1]. All the formulas are verified by considering numerical examples. The approximate solutions are compared with the exact solutions, and also with the solutions of the existing methods. A reliable good accuracy is obtained in all cases.
