Numerical solution of sixth-order boundary-value problems using Legendre wavelet collocation method

•Sixth order boundary value problems using Legendre wavelet collocation method.•Systems of equations obtained from boundary conditions and collocation.•Comparisons with different methods are given in tables. An efficient method is proposed to approximate sixth order boundary value problems. The proposed method is based on Legendre wavelet in which Legendre polynomial is used. The mechanism of the method is to use collocation points that converts the differential equation into a system of algebraic equations. For validation two test problems are discussed. The results obtained from proposed method are quite accurate, also close to exact solution, and other different methods. The proposed method is computationally more effective and leads to more accurate results as compared to other methods from literature.
