Title	Differential equations for recovery of dependence from its harmonics
Authors	N. D. Kuzmichev¹ ¹National Research Mordovian State University
Annotation	The article presents non-homogeneous differential equations used for restoring the derivative of the experimentally studied dependence from its first harmonic. Based on the differential equations of the 2nd and 4th orders, an example of dependence recovery is considered. The solution of the Cauchy problem was carried out numerically by the Runge-Kutta method of the fourth order of accuracy.
