In Chapter 1, the table of contents remains the same. However, many new exercises have been added, and they often introduce models that are new to the text. For example, the theta model for the spiking of a neuron appears in the exercise sets of Sections 1. The concept of a time constant is introduced in Section 1. The velocity of a freefalling skydiver is discussed in three exercise sets. In Section 1.
Chapter 2 has undergone a complete overhaul.
We added a section Section 2. We include this topic for two reasons.
First, many of our students had first-hand experience with the H1N1 pandemic in — Second, many users of the preliminary edition liked the fact that we discussed nullclines in Chapter 2. Section 2. Chapter 2 now has eight sections rather than five.
Sections 2. This model is so important that it deserves a section of its own rather than being buried at the end of a section as it was in previous editions. The remaining analytic techniques that we presented in the previous editions can now be found in Section 2. The Existence and Uniqueness Theorem for systems along with its consequences has its own section Section 2.
This material is presented in smaller sections to give the instructor more flexibility to pick and choose topics from Chapter 2. Only Sections 2. Chapter 2 has always been the most difficult one to teach, and now instructors can cover as many or as few sections from Chapter 2 as they see fit. Pathways Through This Book There are a number of possible tracks that instructors can follow in using this book. Chapters 1—3 form the core with the possible exception of Sections 2.
Most of the later chapters assume familiarity with this material. Certain sections such as Section 1. However, the material on phase lines and phase planes, qualitative analysis, and solutions of linear systems is central. A typical track for an engineering-oriented course would follow Chapters 1—3 perhaps skipping Sections 1.
Appendix A changing variables can be covered at the end of Chapter 1. These chapters will take roughly twothirds of a semester.
The final third of the course might cover Sections 4. Chapters 4 and 5 are independent of each other and can be covered in either order. In particular, Section 5. Appendix B power series goes well after Chapter 4. Incidentally, it is possible to cover Sections 6.
As we have learned from our colleagues in the College of Engineering at Boston University, some engineering programs teach a circuit theory course that uses the Laplace transform early in the course.
Consequently, Sections 6. However, if possible, we recommend waiting to cover Chapter 6 entirely until after the material in Sections 4. Instructors can substitute material on discrete dynamics Chapter 8 for Laplace transforms. A course for students with a strong background in physics might involve more of Chapter 5, including a treatment of systems that are Hamiltonian Section 5.
A course geared toward applied mathematics might include a more detailed discussion of numerical methods Chapter 7. We have sample syllabi contributed by users at various institutions as well as information about workshops and seminars dealing with the teaching of differential equations.
We also maintain a list of errata. Solution Builder, available Copyright Cengage Learning. PREFACE xi to instructors who have adopted the text for class use, creates customized, secure PDF copies of solutions matched exactly to the the exercises assigned for class.
The goal of that project was to rethink the traditional, sophomore-level differential equations course. We are especially thankful for that support. Paul Blanchard Robert L.
For this edition, we owe particular thanks to one individual, Brian Persaud. Over the course of almost two years, he was there when we needed him. He basically did all of the production work that was done at Boston University. He researched countless topics and gave us valuable feedback at every step in the process.
Thanks, Brian. Doug Wright on the second edition, Sebastian Marotta and Dan Look on the third edition, Brian has left his mark on the text in many positive ways. We also had help with the graphics programming from Nick Benes. Nick is currently serving in Afghanistan, but we have the light on in anticipation of his safe return. When we needed some last-minute accuracy checking, Dan Cuzzocreo was the man. We also thank Mark Kramer for giving us copies of his notes on the theta model for the spiking of a neuron.
He saved us countless hours during the formating of the text and the production of the figures. Much of the production work, solutions to exercises, accuracy checking and rendering of pictures was done by former Boston University graduate students Bill Basener, Lee DeVille, and Stephanie Jones during the production of the first edition. They spent many long days and nights in an alternately too-hot-or-too-cold windowless computer lab to bring this book to completion.
Many other individuals at Boston University have made important contributions. In particular, our teaching assistants Duff Campbell, Michael Hayes, Eileen Lee, and Clara Bodelon had to put up with the headaches associated with our experimentation.
Duff also advised us during the development of our power series appendix for the third edition, and he continues to provide valuable feedback whenever he teaches differential equations using this book. We received support from many of our colleagues at Boston University and at other institutions. It was a special pleasure for us to work closely with colleagues in the College of Engineering—Michael Ruane who often coordinates the circuits course , Moe Wasserman who permitted one of the authors to audit his course , and John Baillieul a member of our advisory board.
All contributed their scarce time during workshops and trips to Boston University. This software truly enhances the teaching and learning of differential equations.
As you will see while using these programs, Hu has the ability to visualize differential equations in a way that only an artist as he is can. It is always a pleasure to work with him. The ball's acceleration towards the ground is the acceleration due to gravity minus the acceleration due to air resistance.
Gravity is considered constant, and air resistance may be modeled as proportional to the ball's velocity. This means that the ball's acceleration, which is a derivative of its velocity, depends on the velocity and the velocity depends on time.
Finding the velocity as a function of time involves solving a differential equation and verifying its validity. Types[ edit ] Differential equations can be divided into several types. Apart from describing the properties of the equation itself, these classes of differential equations can help inform the choice of approach to a solution. This list is far from exhaustive; there are many other properties and subclasses of differential equations which can be very useful in specific contexts. Ordinary differential equations[ edit ] Main articles: Ordinary differential equation and Linear differential equation An ordinary differential equation ODE is an equation containing an unknown function of one real or complex variable x, its derivatives, and some given functions of x.
The unknown function is generally represented by a variable often denoted y , which, therefore, depends on x. Thus x is often called the independent variable of the equation. The term "ordinary" is used in contrast with the term partial differential equation , which may be with respect to more than one independent variable.
Linear differential equations are the differential equations that are linear in the unknown function and its derivatives. Their theory is well developed, and, in many cases, one may express their solutions in terms of integrals.
Most ODEs that are encountered in physics are linear, and, therefore, most special functions may be defined as solutions of linear differential equations see Holonomic function. A differential equation is an equation that relates a function with one or more of its derivatives. How to Solve Differential Equations.

Come to Algebra1help. As a consequence, the analysis of nonlinear systems of differential equations is much more accessible than it once was. Studies of various types of differential equations are determined by engi-neering applications. Today, the membership association is Linear Differential Equations In control system design the most common mathematical models of the behavior of interest are, in the time domain, linear ordinary differential equations with constant coefficients, and in the frequency or transform domain, transfer functions obtained from time domain descriptions via Laplace transforms.
We present examples where differential equations are widely applied to model natural phenomena, engineering systems and many other situations.
