Solution of Boundary Value Problems by Approaching Spline Techniques

الملخص EN

In the present work a nonpolynomial spline function is used to approximate the solution of the second order two point boundary value problems.

The classes of numerical methods of second order, for a specific choice of parameters involved in nonpolynomial spline, have been developed.

Numerical examples are presented to illustrate the applications of this method.

The solutions (u(x)) of these examples are found at the nodal points with various step sizes and with various parameters (α, β).

The absolute errors in each example are estimated, and the comparison of approximate values, exact values, and absolute errors of u(x) at the nodal points are shown graphically.

Further, shown that nonpolynomial spline produces accurate results in comparison with the results obtained by the B-spline method and finite difference method.
