ABSTRACT
The important step in studying the qualitative behavior of non-linear dynamical
system is how to detect the presence of chaos. There are several methods that used
to determine the presence of chaos signature. This paper presents a proposed
method in detecting the presence of chaos. This method combines two techniques
namely: the normal form analysis and largest Lyapunov exponent (LLE). Computer
programs were generated to investigate these two techniques and the proposed
detecting method. An example was given to furnish the herein given computer
algebra techniques based on real applications. The obtained results in this work
were verified with that published by other researchers. The proposed method can
provide highly active and efficient ability when studying the nature of non-linear
dynamical systems and its chaotic presence.
