Overview

This course is about differential equations and covers material that all engineers should know. Both basic theory and applications are taught. In the first five weeks we will learn about ordinary differential equations, and in the final week, partial differential equations.

The course is composed of 56 short lecture videos, with a few simple problems to solve following each lecture. And after each substantial topic, there is a short practice quiz. Solutions to the problems and practice quizzes can be found in instructor-provided lecture notes. There are a total of six weeks in the course, and at the end of each week there is an assessed quiz.

Syllabus

First-Order Differential Equations
-A differential equation is an equation for a function with one or more of its derivatives. We introduce differential equations and classify them. We then learn about the Euler method for numerically solving a first-order ordinary differential equation (ode). Then we learn analytical methods for solving separable and linear first-order odes. An explanation of the theory is followed by illustrative solutions of some simple odes. Finally, we learn about three real-world examples of first-order odes: compound interest, terminal velocity of a falling mass, and the resistor-capacitor electrical circuit.

Homogeneous Linear Differential Equations
-We generalize the Euler numerical method to a second-order ode. We then develop two theoretical concepts used for linear equations: the principle of superposition, and the Wronskian. Armed with these concepts, we can find analytical solutions to a homogeneous second-order ode with constant coefficients. We make use of an exponential ansatz, and transform the constant-coefficient ode to a quadratic equation called the characteristic equation of the ode. The characteristic equation may have real or complex roots and we learn solution methods for the different cases.

Inhomogeneous Linear Differential Equations
-We now add an inhomogeneous term to the constant-coefficient ode. The inhomogeneous term may be an exponential, a sine or cosine, or a polynomial. We also study the phenomena of resonance, when the forcing frequency is equal to the natural frequency of the oscillator. Finally, we learn about three important applications: the RLC electrical circuit, a mass on a spring, and the pendulum.

The Laplace Transform and Series Solution Methods
-We present two new analytical solution methods for solving linear odes. The first is the Laplace transform method, which is used to solve the constant-coefficient ode with a discontinuous or impulsive inhomogeneous term. The Laplace transform is a good vehicle in general for introducing sophisticated integral transform techniques within an easily understandable context. We also discuss the series solution of a linear ode. Although we do not go deeply here, an introduction to this technique may be useful to students that encounter it again in more advanced courses.

Systems of Differential Equations
-We learn how to solve a coupled system of homogeneous first-order differential equations with constant coefficients. This system of odes can be written in matrix form, and we learn how to convert these equations into a standard matrix algebra eigenvalue problem. The two-dimensional solutions are visualized using phase portraits. We then learn about the important application of coupled harmonic oscillators and the calculation of normal modes. The normal modes are those motions for which the individual masses that make up the system oscillate with the same frequency.

Partial Differential Equations
-To learn how to solve a partial differential equation (pde), we first define a Fourier series. We then derive the one-dimensional diffusion equation, which is a pde for the diffusion of a dye in a pipe. We proceed to solve this pde using the method of separation of variables.

Very interesting the way the teacher it's just not giving any unknown formulas that come from a physics analysis and tackle the, but he reallym directly makes you learn in a very simple way how to truly understand mathemathics while you're learning differential equations in the road, always viewed from a real physics perspective. Covered the most important subjects gave enough material to practice. Excellent and congratulations.

This course is modeled nicely and taught effectively making more interested. In each video Reviewing that topic covered was more attracted me. I have learnt many things from this course. Modelling using Heaviside was more interesting. SIR model given on CORONA was very interesting make us to thing on the current pandemic . Overall it was very nice and informative Learning .

The course throws light on the applications of ODE which is not often discussed in class for students. This approach will and has brought more interest for me in the subject as I am seeing the applications visually also. Thank you professor.

Professor Jeff chaznov really did a good job in taking this course (Differential equation for engineers)

At first when he started he went back to basic calculus and was nurturing us like babies(for the first three weeks of the course) and I appreciate that a lot. It was easy at first in the first three weeks but it became complex due to the introduction of Laplace transform,Heaviside's step function,Airy's expansion it was really fun cause I learnt a lot and I would love to know more.

This course was really challenging it made me think outside the Box,and I appreciate prof for tutoring this course like this.

I can boast now that there is nothing in calculus that I don't have knowledge of,because of the way this course was treated. I'm still in college but I believe this course will prove very useful in the future.

Thank you very much Jeff chaznov

It was worth it cause u changed lives

I studied differential equations in college many years ago so this is a review for me, and I am taking it with my wife who is taking it for the first time. Both of us find the course to be excellent. We like that the course is broken into many short modules, each with a review problem immediately following to reinforce the material. We find the videos to be generally clear and easy to understand. The examples are interesting and relevant. Our only challenge is finding enough time to complete each week's work. Although the time estimates are reasonable, we can only spend a couple of hours a week on the course so we will probably need 8-10 weeks to finish this 4 week course. We do appreciate being able to reset our deadlines. I would recommend this course to anyone who needs to learn this material, whether for the first time or as a review.

Good course for beigners, but it didn't contain every-thing which was in my syllabus for differential equations. The modelling of Differential equations and how to solve them is perfectly explained. But it doesn't includes Exact Linear Differential Equations, Reducible to Exact form and Reducible to linear form in first order. While in higher order differential equations only second order was considered. In Inhomogenous Higher order Differential Equations Legendre's and Cauchy's equations were not taught. This course also didn't consider the DE of higher degree. Simultaneous Differential equations are also not included in it. In PDE the first order and higher order PDE are not well defined and seperated. The application part was the best but as an improvement animations can be added to the slides. Quite good for revision!

This is an amazing course indeed. The Professor was so amicable and taught nicely. Last week was little bit difficult to me but I overcame the situation. Through the course, I came to know a lot of new things like laplace transform, dirac delta function, solving process of heaviside step function, system of differential equations solving method using matrix algebra, fourier series etc. Which of them was not taught by our teachers during ODE course. In the lecture videos, writing on the transparent screen attracted me most. The lecture note pdf was well arranged. Practise quiz and graded quiz made worth of learning.

Heartiest thanks to Professor for making this course wonderful. Finally, it was a remarkable course on Coursera.

It's a fantastic course to learn! The professor has prepared very detailed, informative and easily-understandable notes for the course, and I really enjoy the teaching style! It's very clear and straightforward. The course covers major consequencial part of the differential equation, especially ODE. I've learned a lot through the course.

One little suggestion: maybe the professor can talk more about PDE later in this course. And also, I'm quited interested in the disfussion application and maybe the professor can talk more about the real-life comprehension of those math equations and results.

Thanks so much for professor's efforts! It's really a rewarding course!

This differential equations course is aimed at engineers and appropriately focuses on physical (and financial) applications. Just enough theory is included to ensure the student can correctly apply the learnings.

The key to success (for me) in this course was to WORK THE PROBLEMS. Learning DE's is not a spectator sport. You've got to sharpen lots of pencils and put in the effort. It will be rewarded. The exercises are well structured and the accompanying e-text is invaluable.

I rated this 5 stars because of how completely I achieved my learning objectives. I will point out that doing so takes approx. twice as long as the time estimates in the syllabus.

It is a good course to learn different techniques to solve a variety of differential equations. Further, we also get surprising results in this course specially in the Fourier Series section which may seem interesting to all. I feel it is a good introduction but if you want to practice more, you may want to search for another course. I found that the number of problems given to solve were just sufficient but I could have fancied more problems to practice. If it is your first time at differential equations after high school, I will definitely recommend it.

In this course, Prof. Chasnov provides an "applications based" approach to differential equations. While the necessary minimum of theory is included, the focus remains on problem solving. As an engineer, I have always approached math as a tool rather than as an end in itself.

I particularly appreciated the many real world examples of how to apply the lecture material. A caution to prospective students - - you won't get much out of this by simply watching the lectures. You MUST do the problem sets to really benefit. It is worth the investment.

This course is very useful in my career. I am entering into an MFE program, and since I did not take PDE in my undergraduate, my program set this course as a prerequiste of PDE. This course is very interesting and easy understand. It took me 1 week to complete when I just concentrate on this course and set everything aside. Now I could take some advanced PDE application course in field of finance. Before this course, I really could not understand what is going on in terms like non-linear solver in my finance book. Great adventure!

For something as abstract as ODEs and PDEs, this course has done a great job in connecting the math, equation solving skills, and the real world applications. I personally enjoyed every lecture video, practice quiz, and graded quiz.

The configuration of the course is very helpful. The introduction of the concepts/skilss, followed by a quick summary in the video, then a practice session before any actual quiz helped me strengthen the material I learnt.

Prof. Chasnov showed great passion about what he teaches!

The course becomes relatively easy if you just do what the Professor tells you to. Basic knowledge about some topics are required, but that requires minimal effort. The explanation is pretty well and since most of the topics are connected, the flow is maintained and it's fun to learn. The most important part is the applications of Differential Equations in real world, as engineers. It's a great experience to learn some of those, especially the Diffusion Equation that covers the very important Fourier Series.

The course is very useful in particular for understanding how different maths skills are related and how important to use differential equation to see the dynamics of any system. The course helps visualize and structuralize all the maths thinking and problem solving skills needed for modelling and problem solving via the very clear presentation by Prof. Jeff and very logical structured and designed course framework. Looking forward to other courses that will be thought by Prof. Jeff in the future.
