Document Summary

Ltv has no ptc and the system is changing. Lti has a ptc and the system is invariant. Net rate of change of fluid volume = 0 = . If 2 is some constant then lti and has ptc. System form: dependent variable on left hand side. Section 2. 7: number 44: rocket motion ( ) = (0 ) . The equation is linear (0 ) + ( ) = (0 ) Lti or ltv? (0 ) coefficients are varying with respect to dependent variable, hence it is ltc therefore. State space: dp dt dp dt dp dt h. Where and are constant coefficients and are linear terms. The associated differential equations comes from application of newton"s law. All problems are lti and has a ptc. All linear constant coefficients in ordinary differential equations have a single form of their solutions. = + = 0 is what we are looking for (unknown) = 0,
