Abstract :
The conditions for a polynomial response and obtaining its analytical expression are considered. The responses in a forced regime of work arise from a linear input/output system of second order with varying coefficients in time of a polynomial type. The necessary and sufficient conditions have been obtained for the forced response of the system to be of a polynomial shape in time. An analytical expression of this response is given
