There's lots of good stuff in Taubes, "Modeling Differential Equations in Biology" The control structure of governing partial differential equations (PDEs) is changed into appropriate ordinary differential equations (ODEs) by suitable transformations. A fractional differential equations (FDEs)-based theory involving 1- and 2-term equations was developed to predict the nonlinear survival and growth curves of foodborne pathogens. Differential Equations: some simple examples, including Simple harmonic motionand forced oscillations. In elementary ODE textbooks, an early chapter is usually dedicated to first order equations. Separation of the variable is done when the differential equation can be written in the form of dy/dx = f(y)g(x) where f is the function of y only and g is the function of x only. I have the same problem. I am not sure what you mean by 'cool', but differential equations are in more places than you might think. Differential equations first came into existence with the invention of calculus by Newton and Leibniz.In Chapter 2 of his 1671 work Methodus fluxionum et Serierum Infinitarum, Isaac Newton listed three kinds of differential equations: = = (,) ∂ ∂ + ∂ ∂ = In all these cases, y is an unknown function of x (or of and ), and f is a given function. Included are most of the standard topics in 1st and 2nd order differential equations, Laplace transforms, systems of differential eqauations, series solutions as well as a brief introduction to boundary value problems, Fourier series and partial differntial equations. We also give some improvements for the proof of the existence and uniqueness of the solution in fractional differential equations.
