Simple mathematical models
WebbMathematical Modeling and Basic Concepts Model and Mathematical Model: According to Lesh and Doerr (2003a), a model consists of both conceptual systems in learners’ minds and the external notation systems of these systems (e.g., ideas, representations, rules, and materials). A model is used to understand and interpret complex systems in nature. WebbCreating a mathematical model: • We are given a word problem • Determine what question we are to answer • Assign variables to quantities in the problem so that you can answer the question using these variables • Derive mathematical equations containing these variables • Use these equations to find the values of these variables

Webb1 sep. 1971 · Simple models are developed for gravity drainage where vertical flow occurs, for water underrunning of viscous oils, for gravity segregation of water banks in gas caps, and for control of coning by injection of oil. Introduction WebbAbstract. First-order difference equations arise in many contexts in the biological, economic and social sciences. Such equations, even though simple and deterministic, can exhibit a surprising array of dynamical behaviour, from stable points, to a bifurcating hierarchy of stable cycles, to apparently random fluctuations. There are consequently ...
