hallo every body 

please can you help me 

how do i solve this differential linear system with respect lambda is positive number  

i use maple 18

Let the differential system with $\lambda>0$

\begin{equation}
\begin{array}{ccc}
\dot{x}=y(t)\\
\dot{y}=z(t)\\
\dot{z}=-\lambda y(t)-h(t)
\end{array}
\end{equation}
