We will again be offering this course during the Spring 2020 semester. We'll be following the lead of the mainstream 18.03 course and not have a specific required text. However, you may still want to use a reference text. See the left column and links for recommended texts. All problem sets will be made available as printable PDFs. Much of the course material will be derived from the 18.03 Supplementary Notes by Prof. Haynes Miller (used in recent years in the mainstream version of this course), the 18.03 Notes and Exercises by Prof. Arthur Mattuck, and Lecture Notes written specifically for our course.

This course employs a series of specially written Java™ applets, or Mathlets, developed by the Mathematics Department. Each problem set typically contains a problem based around one or another of them. [Full catalog of Mathlets from Math Dept.]

18.01 (Single Variable Calculus) is a prerequisite; 18.02 (Multivariable Calculus) is a corequisite, meaning students may take 18.02 and 18.03 simultaneously.
Texts: None required, but two good optional textx are:
(1) Differential Equations & Linear Algebra by Farlow, Hall, McDill, West. This text is published by Pearson and has ISBN #9780131860612.
(2) Elementary Differential Equations with Boundary Value Problems. 6th ed. by Edwards, C., and D. Penney. Upper Saddle River, NJ: Prentice Hall, 2008. ISBN: 9780136006138. [Note: The 5th Edition (ISBN: 9780131457744) or the 4th Edition will serve as well.]
Students will also need two sets of notes "18.03: Notes and Exercises" by Arthur Mattuck, and "18.03 Supplementary Notes" by Haynes Miller (both available online at no cost). We will primarily use these notes and our own Lecture Notes which may be revised as the course proceeds. Additional supplements may also be provided.
This course is a study of Ordinary Differential Equations (ODE's), including modeling physical systems. Topics include:
- Solution of First-order ODE's by Analytical, Graphical and Numerical Methods;
- Linear ODE's, Especially Second Order with Constant Coefficients;
- Undetermined Coefficients and Variation of Parameters;
- Sinusoidal and Exponential Signals: Oscillations, Damping, Resonance;
- Complex Numbers and Exponentials;
- Fourier Series, Periodic Solutions;
- Delta Functions, Convolution, and Laplace Transform Methods;
- Matrix and First-order Linear Systems: Eigenvalues and Eigenvectors; and
- Non-linear Autonomous Systems: Critical Point Analysis and Phase Plane Diagrams.
The Concourse version of the 18.03 course will closely parallel the mainstream 18.03 course. As has been the case for the last few semesters, there will be additional emphasis on Linear Algebra throughout the course, and some topics listed above may be less emphasized than in previous years.
The lecture period is used to help students gain expertise in understanding, constructing, solving, and interpreting differential equations. Students must come to lecture prepared to participate actively. Students may sometimes be asked to spend a minute responding to a short feedback question at the end of the lecture.
These meet twice a week to discuss and gain experience with the course material. Even more than the lectures, the recitations involve active participation. The recitation leader may begin by asking for questions or hand out problems to work on in small groups. Students are encouraged to ask questions early and often.
Regular office hours at times to be determined. You are encouraged to drop by for any matters that cannot adequately be addressed in class.
Tutors/graders are available within Concourse. Another resource of great value to students is the Mathematics Department tutoring room. This is staffed by experienced undergraduates. This is a good place to go to work on homework (as is the Concourse Lounge).
You may find the 18.03 lecture videos of Arthur Mattuck helpful. They are available on the Open Courseware site and were recorded in Spring 2003.
The Ten Essential Skills
Students should strive for personal mastery over the following skills. These are the skills that are used in other courses at MIT. This list of skills is widely disseminated among the faculty teaching courses listing 18.03 as a prerequisite. At the moment, 140 courses at MIT list 18.03 as a prerequisite or a corequisite.
- Model a simple system to obtain a first order ODE. Visualize solutions using direction fields and isoclines, and approximate them using Euler's method.
- Solve a first order linear ODE by the method of integrating factors or variation of parameter.
- Calculate with complex numbers and exponentials.
- Solve a constant coefficient second order linear initial value problem with driving term exponential times polynomial. If the input signal is sinusoidal, compute amplitude gain and phase shift.
- Compute Fourier coefficients, and find periodic solutions of linear ODEs by means of Fourier series.
- Utilize Delta functions to model abrupt phenomena, compute the unit impulse response, and express the system response to a general signal by means of the convolution integral.
- Find the weight function or unit impulse response and solve constant coefficient linear initial value problems using the Laplace transform together with tables of standard values. Relate the pole diagram of the transfer function to damping characteristics and the frequency response curve.
- Calculate eigenvalues, eigenvectors, and matrix exponentials, and use them to solve first order linear systems. Relate first order systems with higher-order ODEs.
- Recreate the phase portrait of a two-dimensional linear autonomous system from trace and determinant.
- Determine the qualitative behavior of an autonomous nonlinear two-dimensional system by means of an analysis of behavior near critical points.
The Ten Essential Skills is also available as a (PDF).
Homework assignments typically will have two parts: a first part drawn from the book or notes, and a second part consisting of problems which will be handed out. Both parts are keyed closely to the lectures. Students should form the habit of doing the relevant problems between successive lectures and not try to do the whole set the night before they are due.
There are 3 one-hour exams held during lecture session and a three-hour comprehensive final examination.
The final grade will be based on the following scheme (subject to minor modification):
25% homework, 35% hour exams, 40% Final Exam
ODE Manipulatives ("Mathlets"):
This course employs a series of specially written Java™ applets, or Mathlets, developed by the Mathematics Department. They may be used in lecture occasionally, and each problem set typically contains a problem based around one or another of them.
Topics and Assignments are posted in the Course Calendar.
