I'm taking this course too, and it is my first signature track certificate to be as well. It's Week 6 now, and the impressions are very good. Definitely worth the money, in my oppinion.

Yup, and this is why Coursera courses are excellent in general - they're mostly led by industry professionals who are "in the thick of it".

I'm attending the course and the first impressions are great - the professor is great, there's a lots of readings, links and materials posted, and I expect anyone interested in the subject will profit greatly by taking the course.

These courses mostly work on the following principle: you have video lectures offered every week (following a specific course syllabus), and you can watch them whenever you want. However, you also have weekly assignments which have a due date for completion. In general, the platforms work just...

You mean, a statically indeterminate structure. You should look into the force method for this. Depends on what you need, I think you may also find tables with moment diagrams for such beams.

Unless I'm missing something, n has to be a natural number. Numbers of the form 1/n, where n is natural, are rational numbers.

For a. Is 1 <= x, for all x in your set? Revise the definitions of "greatest lower bound", i.e. "infimum".

The alduin fight wasn't specially difficult, I'm playing on normal difficulty though. I find it interesting that some stupid fights with some wildlife or forsaken appear to be more difficult at times. I'm at level 37 now, and at a point where I feel I'm not too strong - I want weapons with...

No "No!" option? Too much interventionism for me.

Happy New Year!

Could you paste your code here? Perhaps it's a problem of local/global variables? Do you refer to a variable which is defined inside a function?

Set up the linear combination and make it equal to your vector in order to find the coefficients a, b.

The difference is in the forces they "exhibit", as you stated. In beam elements, in general, you have a longitudinal force (tension or compression), a bending moment and a shear force. Of course, this goes for a 2D beam element. A frame is a system composed of beam elements, while a truss is a...

If this is really true, then it is terrible.

Well, let ε be some number in <0, 1>. Does there exist some positive integer N such that for all m, n >= N you have |xm - xn| < ε? Edit: sorry, micromass seems to have answered first.
