Antwi A. Akom,Aekta Shah,Aaron Nakaiodel is made up of one or several equations from which we aim to determine one or several unknown quantities of interest in terms of other, prescribed, quantities. The unknown quantities turn out in many cases to be functions of a set of variables. Since very often the physical or empirical laws gov

Even if the model is nonlinear, the study of its linearized version can provide valuable hints about the quantitative and qualitative behavior of the full model, and perhaps suggest a method that might lead to its complete solution.
