ON PERIODICITY OSCILLATORY SOLUTIONS OF LINEAR NEUTRAL DIFFERENTIAL EQUATIONS WITH SECOND ORDER CONSTANT COEFFICIENT |
| |
| Abstract: | This paper discusses linear neutial differential equations with second order constant coefficient. The sufficient and necessary conditions are presented when the equations have periodicity oscillatoly solutions with attenuation amplitude of vibiarion. The method to solve this kind of equations is also shown in this paper. |
