The influence of violations of the conditions of Theorem Sampling on results of the numerical integration of the equations of motion of nonlinear dynamical systems is demonstrated by the example of modeling of self-oscillations in the Van der Pol oscillator. It is shown that the phenomenon of frequency locking is found in the numerical solution for autonomous self-oscillating system.
