We answer Totik's question on weighted Bernstein's inequalities by showing that

holds for all trigonometric polynomials and certain nondoubling weights . Moreover, we find necessary conditions on for Bernstein's inequality to hold. We also prove weighted Markov, Remez, and Nikolskii inequalities for trigonometric and algebraic polynomials.
