Direct Method for Variational Problems Using Boubaker Wavelets

The wavelets have many applications in engineering and the sciences, especially mathematics. Recently, 2021, wavelet Boubaker (WB) polynomials were used for first time to study their properties detail. They also utilized solving Lane-Emden equation. aim of this paper is show truncated Wavelet variation problems. In research, direct method using was presented variational reduces problem into a set linear algebraic equations. fundamental idea problems convert function one that involves finite number variables. Different numerical examples given demonstrate applicability validity Matlab program. Also, results technique compared with exact solution, graphs added these test convergence method.
