Course Highlights

This course includes lecture notes, assignments, and a full set of video lectures.

Course Description

Differential Equations are the language in which the laws of nature are expressed. Understanding properties of solutions of differential equations is fundamental to much of contemporary science and engineering. Ordinary differential equations (ODE's) deal with functions of one variable, which can often be thought of as time. 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.

Important Notes : -

It is a collection of lectures notes not ours. Our subjective is to help students to find all engineering notes with different lectures PowerPoint slides in ppt ,pdf or html file at one place. Because we always face that we lose much time by searching in Google or yahoo like search engines to find or downloading a good lecture notes in our subject area with free. Also it is difficult to find popular authoress or books slides with free of cost. If you find any copyrighted slides or notes then please inform me immediately by comments or email as following address .I will take actions to remove it. Please click bellow to download ppt slides/ pdf notes. If you face any problem in downloading or if you find any link not correctly work or if you have any idea to improve this blog/site or if you find any written mistake or you think some subjects notes should be include then give your suggestion as comment by clicking on comment link bellow the post (bottom of page) or email us in this address engineeringppt.blogspot@gmail.com?subject=comments on engineeringppt.blogspot.com. I will must consider your comments only within 1-2 days. if you have any good class notes/lecture slides in ppt or pdf or html format then please you upload these files to rapidshare.come and send us links or all files by our email address engineeringppt.blogspot@gmail.com?subject=comments on engineeringppt.blogspot.com.

To find your notes quickly please see the contents on the right hand side of this page which is alphabetically arranged and right click on it. After clicking immediately you find all the notes ppt/pdf/html/video of your searching subjects.

It is better to search your subject notes by clicking on search button which is present at middle of right side of this web page. Then enter your subject and press enter key then you can find all of your lectures notes and click on it.

Lecture Notes

Below are the lecture notes for every lecture session. Some lecture sessions also have supplementary files called "Muddy Card Responses." Students pick up half pages of scrap paper when they come into the classroom, jot down on them what they found to be the most confusing point in the day's lecture or the question they would have liked to ask. Responses are then made available to all students on the class Web site.

Video Lectures

These video lectures of Professor Arthur Mattuck teaching 18.03 were recorded live in the Spring 2003 and do not correspond precisely to the lectures taught in the Spring of 2006. Professor Mattuck has inspired and informed generations of MIT students with his engaging lectures.

The videotaping was made possible by The d'Arbeloff Fund for Excellence in MIT Education.

Note: Lecture 18, 34, and 35 are not available.
