Vector Calculus for Engineers

The Hong Kong University of Science and Technology via Coursera


Vector Calculus for Engineers covers both basic theory and applications. In the first week we learn about scalar and vector fields, in the second week about differentiating fields, in the third week about multidimensional integration and curvilinear coordinate systems. The fourth week covers line and surface integrals, and the fifth week covers the fundamental theorems of vector calculus, including the gradient theorem, the divergence theorem and Stokes’ theorem. These theorems are needed in core engineering subjects such as Electromagnetism and Fluid Mechanics.

Instead of Vector Calculus, some universities might call this course Multivariable or Multivariate Calculus or Calculus 3. Two semesters of single variable calculus (differentiation and integration) are a prerequisite.

The course is organized into 53 short lecture videos, with a few problems to solve following each video. 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 five weeks to the course, and at the end of each week there is an assessed quiz.

  • Vectors
    • A vector is a mathematical construct that has both length and direction. We will define vectors and learn how to add and subtract them, and how to multiply them using the scalar and vector products (dot and cross products). We will use vectors to learn some analytical geometry of lines and planes, and learn about the Kronecker delta and the Levi-Civita symbol to prove vector identities. The important concepts of scalar and vector fields will be introduced.
  • Differentiation
    • Scalar and vector fields can be differentiated. We define the partial derivative and derive the method of least squares as a minimization problem. We learn how to use the chain rule for a function of several variables, and derive the triple product rule used in chemical engineering. We define the gradient, divergence, curl and Laplacian. We learn some useful vector calculus identities and how to derive them using the Kronecker delta and Levi-Civita symbol. Vector identities are then used to derive the electromagnetic wave equation from Maxwell's equation in free space. Electromagnetic waves form the basis of all modern communication technologies.
  • Integration and Curvilinear Coordinates
    • Integration can be extended to functions of several variables. We learn how to perform double and triple integrals. Curvilinear coordinates, namely polar coordinates in two dimensions, and cylindrical and spherical coordinates in three dimensions, are used to simplify problems with circular, cylindrical or spherical symmetry. We learn how to write differential operators in curvilinear coordinates and how to change variables in multidimensional integrals using the Jacobian of the transformation.
  • Line and Surface Integrals
    • Scalar or vector fields can be integrated on curves or surfaces. We learn how to take the line integral of a scalar field and use line integrals to compute arc lengths. We then learn how to take line integrals of vector fields by taking the dot product of the vector field with tangent unit vectors to the curve. Consideration of the line integral of a force field results in the work-energy theorem. Next, we learn how to take the surface integral of a scalar field and compute surface areas. We then learn how to take the surface integral of a vector field by taking the dot product of the vector field with the normal unit vector to the surface. The surface integral of a velocity field is used to define the mass flux of a fluid through the surface.
  • Fundamental Theorems
    • The fundamental theorem of calculus links integration with differentiation. Here, we learn the related fundamental theorems of vector calculus. These include the gradient theorem, the divergence theorem, and Stokes' theorem. We show how these theorems are used to derive continuity equations, derive the law of conservation of energy, define the divergence and curl in coordinate-free form, and convert the integral version of Maxwell's equations into their more aesthetically pleasing differential form.

    The course is excellent, it helps you expand your knowledge within calculus and allows you to see the applications it has, since in engineering matters this knowledge is widely applied in any area.

    The demonstrations required by the course allow you to develop new math skills.

    Professor Chasnov is very good at explaining the topics of the course, I liked his excellent teaching style, I think this is what makes the course in general understandable. I highly recommend this course to people who want to increase their mathematical knowledge, especially in the area of ​​calculus. I hope the teacher continues to teach this type of course.

    This course covers all essential concept of partial, line and surface integral, gradient, divergence, curl, laplacian which are the useful mathematical tools for convert the abstraction of physics theory to nice, able to evaluated equations.

    Overall, the content of this course is more difficult than the general conception of matrix algebra and differential equation course , the formulas is complicated and its application is abstract and theoretical. It takes more time to digest these new knowledge! More challenging more attractive of the world of mathematics. Worth your time to enroll this course!

    This course has been one of the most challenging I've taken in a long time but at the same time probably also the most enriching and important courses, providing all the missing puzzle-pieces and tools I was looking for to move forward in my other interest areas.

    It was amazing how much I learned in these few weeks. I already look forward to applying some of what I learned here in my next course on discrete differential geometry, and I'll be sure to visit the other courses in the series soon as well.

    Thank you!

    I think this class was extremely well taught, but recommend more specific examples that tie in with the theory. Admittedly, I have been out of school for some time now and for this reason, this class was challenging to me. A very good cover of topics, however, and I found it to prove me with the opportunity to refresh my knowledge. Thank you for the opportunity to take this class with such a professional and knowledgeable professor. I hope to take another class with him sometime in the near future.

    Well structured and self explainatory videos with interesting assignments. All the major topics even those which are not taught in university courses. I personally found the description of different coordinate systems quite fascinating. Plus at the end of the course there were videos on the physical significance of divergence and curl. The application of vector calculus in solving Maxwell's equations was also quite interesting. Thoroughly enjoyed the course.

    This indeed is one of the BEST courses in Vector Calculus with the BEST instructor teaching it. Professor Chasnov is highly organized and presents the contents in a clear manner. I have become fond of his excellent teaching style. Over and above, all engineers must take this course. I hope he teaches courses in PDEs, Integral Transforms, Complex Variables, ... in times to come to benefit the motivated mathematics learners all around the globe! This is terrific effort from him. I wish the best comes his way as a reward for his dedication. God bless.

    One of the best courses with the best teaching method from Professor Chasnov. Thank so much Professor Chasnov and Coursera for giving me the opportunity to learn such difficult concepts of vector calculus. I am pretty sure that these concepts would be really handy in learning new concepts such as the displacement field of laminated composites with defects, potential fields for smart materials, magnetic fields for energy harvesting.

    Starting from the very basic, the course takes to the advanced concepts on Vector calculus. I took this course as a refresher and found it very helpful. The large number of reading problems helped strengthen the understanding. For some topics, when the professor mentions something but doesn't go at length to explain, some secondary complementary resources could be useful. I used khan academy videos to fill in the gaps.

    Week three is the pivotal week for learning that I struggled with. Line and Surface integrals just did not come easy to me. A tutorial on the line and surface integrals in greater depth would have helped me since it is difficult to visualize what these always mean. The instruction was excellent, but I feel I needed extra help. Would love to take a course in just line and surface integrals.

    An extremely valuable course for anyone in physics or engineering. Take it as soon as you can.

    It is an outstanding course based on five weeks. It includes all basics you need to know to be involved in Vector Calculus. From Vectors, Operators, Differentiation, Integration (Line and Surface integrals), Curvilinear Coordinates, and Fundamental Theorems. Also, it provides a book with detailed information on each topic. So then, Jeffrey Chasnov thanks for this amazing journey.

    I would like to thank the Professor Jeffrey for all!!!

    This course is a valious tool for students, teachers, engineers, interested in this area of knowlege because here exist a didactic content , very dificcult to meet in traditional books!!!

    Good luck for everyone!!!
  • Prashant Kanuru
    Gets in Deep into abstractions. The 3rd and 4th week are deep but great. I would be happy if some more depth in terms of optimization is added up through Lagrange Multipliers and if some more depth by bringing in Vector Spaces is done, would be great.

    All The Best!!!
