Differential and difference equations constitute main tools that scientists and engineers use to make mathematical models of important practical problems. This course aims to involve engineering students in mathematical modelling by means of differential and difference equations and to develop skill with solution techniques in order to understand complex physical phenomena. The students who succeeded in this course; At the end of this course, students will learn; 1) formulating a model, using differential or difference equations; 2) analyzing the model, both by solving the differential (difference) equation and by extracting qualitative information about the solution from the equation; 3) interpreting the analysis in light of the physical (practical) setting modeled in step 1). Differential equations and solutions, models of vertical motion, single-species population models, multiple-species population models, mechanical oscillators, modeling electric circuits, diffusion models, modeling by means of difference equations.
