The purpose of this paper is to investigate instability of the trivial solution of non-linear vector differential equation of the fifth order by constructing a Lyapunov function to get a new instability result and also to give an example indicate the importance of the topic. Related to a scalar differential equation mentioned in the literature, the findings of this study are beneficial for result of instability of the trivial solution of five order non-linear vectoral differential equations.
