Please write this following our layout guide Tagged since July 2009 A picture of airflow . This model shows the airflow when it goes into a duct . It was modeled using the Navier-Stokes equations A differential equation is a mathematical equation that involves variables like x or y, as well as the rate at which those variables change. While listening to a weather forecast , the meteorologist might say that the air pressure is 772 and falling. The fact that the air pressure is falling is as important to predicting the weather as the actual pressure itself. This is the kind of situation that might be described by a differential equation. Many areas of science engineering , and economics use differential equations. The magnetic field inside an electromagnet depends on the rate at which the electric current passing through it is changing. Force is equal to the rate at which momentum changes. The rate at which the value of the dollar is falling might tell us something about the rate at which the price of gold is rising. In

Problem Set Index Let's start with a definition of a differential equation. A differential equation is an equation that defines a relationship between a function and one or more derivatives of that function. Let y be some function of the independent variable t . Then following are some differential equations relating y to one or more of its derivatives. The equation states that the first derivative of the function y equals the product of and the function y itself. An additional, implicit statement in this differential equation is that the stated relationship holds only for all t for which both the function and its first derivative are defined. Some other differential equations: The typical real world situation that involves modeling with differential equations is one in which a quantity that changes in time, y(t) , is related to the rate at which it changes, , and/or the acceleration of the change, . Usually these relationships can be stated in equations such as those above without knowing the exact function y(t) that satisfies the relationship. To solve a differential equation means to find a

Next: About this document Differential Equations Comp Neuroscience PDF Version of Notes Neural processes are dynamic phenomena, which means that they change in time. These temporal variations are extremely important; indeed, many sensory stimuli are coded according tho firing rates of the neurons and not their absolute membrane potentials. The most accepted models of memory and learning depend on the rates of change of the neurons, that is, the correllation between the activities of the post- and pre-synaptic cells. Recent evidence has pointed to the importance of 40 Hz oscillations in binding diverse properties of visual and olfactory stimuli. Dynamic phenomena play an obvious role in motor activity as well. Locomotion, whether stereotypical, such as trotting of horses and grinding of the lobster stomato-gastric system, or driven by feedback, as in navigation of an obstacle course, depends on precise temporal relations between the limbs and the various components of the locomotor event. Autonomic processes such as breathing, hormonal secretion, circadian cycles, and others also depend on temporal processes such as regular rhythms and more complex phemonena, e.g. spike bursts and irregular activity. Many pathologies are due to temporal difficulties in neural systems; notable among these are epilepsy, Parkinsonian seizures, and various EEG abnormalities. Indeed, the EEG is nothing more than a time series of the lumped activity of many active neurons.

Next: Markov chains Up: Random WalksMarkov Chains Previous: Monte Carlo Integration Differential Equations One of the classic scientific applications of the Monte Carlo method is in the solution of differential equations. The cautions about the applicability of Monte Carlo that were mentioned earlier, are especially important here. Using Monte Carlo to solve differential equations is very inefficient , but if there are special conditions then it might be the best way to go. The idea here is to set up a random walk within the domain that the equation applies, starting at the point at which we want the solution. The probability of moving in each possible direction is determined by the differential equation that is being solved, it is not necessarily the same in each direction. The random walk continues until the particle reaches the boundary of the domain. At this point the particle may be absorbed, the probability of this occuring depends upon the type of boundary condition that applies at that point. If the particle is not absorbed, the walk continues on until it reaches a boundary and finally does get absorbed. As a simple example, let us consider the steady state temperature distribution of a annulus. Lets assume that the inner radius (

Announcements What is AUTO? Evolution Distribution ... Lecture Notes AUTO SOFTWARE FOR CONTINUATION AND BIFURCATION PROBLEMS IN ORDINARY DIFFERENTIAL EQUATIONS This is the Home Page of the AUTO Web Site, established in January 1996. ANNOUNCEMENTS [February 14, 2010] Version 0.7 of AUTO-07p is available at SourceForge. INTRODUCTION AUTO is a software for continuation and bifurcation problems in ordinary differential equations, originally developed by Eusebius Doedel, with subsequent major contribution by several people, including Alan Champneys, Fabio Dercole, Thomas Fairgrieve, Yuri Kuznetsov, Bart Oldeman, Randy Paffenroth, Bjorn Sandstede, Xianjun Wang, and Chenghai Zhang. AUTO can do a limited bifurcation analysis of algebraic systems of the form f(u,p) = 0, f,u in R n and of systems of ordinary differential equations of the form u'(t) = f(u(t),p), f,u in R n subject to initial conditions, boundary conditions, and integral constraints. Here p denotes one or more parameters. AUTO can also do certain continuation and evolution computations for parabolic PDEs. It also includes the software HOMCONT for the bifurcation analysis of homoclinic orbits. AUTO is quite fast and can benefit from multiple processors; therefore it is applicable to rather large systems of differential equations. For further information and details, see the

Transform Methods for Solving Partial Differential Equations, Second Edition problems taken from the actual scientific and engineering literature. Transform methods provide a bridge between the commonly used method of separation variables and numerical techniques for solving linear partial differential equations. While in some ways similar to separation of variables and numerical transform methods can be effective for a wider class of problems. Even when the inverse of the transform cannot be found analytically, numeric and asymptotic techniques now exist for their inversion. Because the problem retains some of its analytic aspects, one can gain greater physical insight than typically obtained from a purely numerical approach. Transform Methods for Solving Partial Differential Equations, Second Edition illustrates the use of Laplace, Fourier, and Hankel transforms to solve partial differential equations encountered in science and engineering. The author has expanded the second edition to provide a broader perspective on the applicability and use of transform methods and incorporated a number of significant refinements: New in the Second Edition: Expanded scope that includes numerical methods and asymptotic techniques for inverting particularly complicated transforms Discussions throughout the book that compare and contrast transform methods with separation of variables, asymptotic methods, and numerical techniques Many added examples and exercises taken from a wide variety of scientific and engineering sources

120. Lee Lady: Calculus For The Intelligent Person A set of downloadable lectures. http://www.math.hawaii.edu/~lee/calculus/#Series-Sol

Calculus for the Intelligent Person Lee Lady For years, I used to tell people that I wished someone would write Calculus for Dummies , using the style of that popular series. Namely, I wanted a book written by someone who actually knows how to write how-to books instead of by a mathematician writing something that will make sense to other mathematicians. Then one day in the bookstore, I discovered that someone had finally done this. But looking through it, I saw that it was not what I had hoped for at all. Although certainly more readable then most calculus textbooks (which, I must say, is certainly not saying a lot), and probably very helpful for many students (see the reviews on Amazon Calculus For Dummies seemed to simply take the standard approach to calculus and present it in a more intelligible fashion without offering much more real insight. The notes that follow are not addressed to beginning students, and certain not to dummies. They are addressed to students who have already seen these concepts presented in class, and have probably done quite a few homework problems, but found that somehow they still didn't see what the basic ideas were. These are thoughts that occurred to me after I had presented these concepts on the blackboard many many times, and then one day asked myself, "Yeah, fine, but what is this actually saying?" Many books and a lot of professors do a fine job of explaining on intuitive grounds the standard definition of the derivative of a function in terms of a limit. For my part, for most of my life I preached to students that in fact the concept of the limit is the foundation for all of calculus.
