In this paper the problem of verified numerical computation of algebraic fast decreasing polynomials approximating the Dirac delta function is considered. We find the smallest degree of the polynomials and give precise estimates for this degree. It is shown that the computer algebra system Maple does not always graph such polynomials reliably because of evaluating the expressions in usual floating-point arithmetic. We propose a procedure for verified computation of the polynomials and use it to produce their correct graphic presentation in Maple.
