A new formula expressing explicitly the derivatives of Bernstein polynomials of any degree and for any order in terms of Bernstein polynomials themselves is proved, and a formula expressing the Bernstein coefficients of the general-order derivative of a differentiable function in terms of its Bernstein coefficients is deduced. An application of how to use(More)
Keywords: Bernstein polynomials Spectral method High order differential equations a b s t r a c t A new explicit formula for the integrals of Bernstein polynomials of any degree for any order in terms of Bernstein polynomials themselves is derived. A fast and accurate algorithm is developed for the solution of high even-order boundary value problems (BVPs)(More)

It is well known that spectral methods (tau, Galerkin, collocation) have a condition number of O.N 4 / where N is the number of retained modes of polynomial approximations. This paper presents some efficient spectral algorithms, which have a condition number of O.N 2 /, based on the ultraspherical-Galerkin methods for the integrated forms of second-order(More)
