“…The optimal stable, nonnegative Bernstein polynomial basis gained popularity among several researchers and useful properties have been applied to solve regular as well as singular second to higher order BVPs and eigenvalue problems [ [9] , [10] , [11] , 22 , 23 , [29] , [30] , [31] , [32] , [33] , [34] , [35] , [36] , [37] , [38] ]. As stated in [22] , the polynomials can be used to form a basis over [0, 1] which is complete.…”
