Due to their simplicity these are suitable for those who deal with this topic and want to gain useful experience in this field. Furthermore, our aim is to give these equations a general form which facilitates the studying of the different models by computer even for an individual programmer. At the same time it facilitates the use of different mathematical auxiliary-programmes. By giving the equations this way we get a chance of studying the relations between the individual systems.application/pdfnonlinear differential equation systemgrowth modelcombat modelprey-predator modeloscillationfolyóiratcikkOpen AccessGábor Gedahttps://doi.org/10.5485/TMCS.2008.0164Teaching Mathematics and Computer Science16Teach.
