Three extremal problems for trigonometric polynomials are studied in this paper. The first was initiated by Maiorov. It relates to the trigonometric polynomials with n nonzero harmonics. The L p -norm of the Weyl derivative is compared with the L q -norm of the polynomial. The other two problems hav
