### The determination of the potential q (x) in terms of natural frequencies of oscillations

Title The determination of the potential q (x) in terms of natural frequencies of oscillations I. M. Utyashev11Mavlyutov Institute of Mechanics, Ufa Branch of the Russian Academy of Sciences The problem of determining the potential $q (x)$ of a special type with respect to natural frequencies of oscillations is considered. In particular, we consider a potential of the form $q (x) = q_1 + q_2 x$, which describes a linear change in the elasticity coefficient of the medium. It is shown that the coefficients $q_1$ and $q_2$ characterizing the linear change in the elasticity coefficient of the medium are uniquely determined by the three natural frequencies of the string vibrating in this medium.
