comment Why does $1+2+3+\cdots = -\frac{1}{12}$?
@GottfriedHelms, I don't know. Probably there is a way to evaluate not only c coefficient (-1/12) of this parabola, but a and b too. It works only with infinite number of points (excel can process only finite set).

@abstractnature, I typed in latex by myself with help of MathJax basic tutorial and quick reference. Also I used Detexify2 service for getting '\' code in latex. Why did you ask about it?

comment Solid angle between vectors in n-dimensional space
@Martin, you are right. Sorry for my mistake. I meant Exterior product there and I've already fixed my answer with it.
