The derivative approximation program is a tool designed to calculate the approximation of a derivative using four different methods: Mid-point approximation, left approximation ...

The user can modify the limits used in the program to calculate the approximation. By adjusting the limits, the program can calculate the derivative of any function in the desired range. Additionally, ...

Asymptotic approximations of radiation integrals: Endpoint and double endpoint diffraction

Abstract: The asymptotic approximation of a radiation integral, in which the integrand has a stationary phase point near one of the integration boundaries, is well known (endpoint diffraction). An ...

Polynomial Approximations of Functions with Endpoint Singularities and Product Integration Formulas

Several problems of mathematical physics lead to Fredholm integral equations of the second kind where the kernels are either weakly or strongly singular and the known terms are smooth. These equations ...
