Fantastic course! I learned how to mathematically model mode shapes for simple 1DOF and 2DOF systems. The instructor was very easy to follow and very thorough.

Good for review

The instructor does make occasional errors in week 5 like the determinant square. the equations and the cases seem not to be 100% consistent eg the 2 DOF system having two end walls or one wall was interchanged. otherwise the results that arrived from the math are good and profound

A good introduction to the mathematics of vibrations, if a little difficult to follow.

Sometimes the professor lost himself, but it is really easy to understand.

Besides the amazing ability of the professor to write backwards such a Leonardo da Vinci, the course was not provide me what I expected. Too much mathematics, too much theory. I was expecting more practical applications and problem examples. In addition, I guess that for MOOC, the material should be already done in a presentation so the instructor can focus on explanation and examples and doing the lecture more dynamic and less time consuming. Almost an hour to explain a curve and a couple of equations is not practical for people that are interesting in learn by themselves.

The professor is so monotonous, and the lecture is going at a slow pace. The professor is also not looking into the screen. This is supposed to be a course not a lecture series. There is nothing new that the professor is teaching and there is nothing new that will bring the insights to the course. Just the same old course packaged as a MOOCS. Please improve
