Abstract
This paper is devoted to the derivation of exact formulas for trigonometric sums at different nodes. These sums are obtained by the use of Hermite interpolations whose nodes are basically zeros of Chebyshev polynomials of the first and second kinds. We prove that some trigonometric sums are integer-valued and we derive some asymptotic formulas.
