Given that I haven't updated the notes on the circular functions in ages, I decided I might as well start making the translations. First, Spanish

I AM ALIVE and I have once again decided to overhaul the navigation because I am indecisive.

redid the UI again so it takes up less space. if you're seeing that the site content takes up almost no space, the thumbnail just needs to refresh

Finally overhauled the website. Now everything is in an iframe and there's a bar at the top for navigation.

I'll get back to updating the site eventually, but i think the whole thing could use an overhaul

>the_quintic_problem By the way historically the origin was the quintic problem. But that era has ended and Galois theory is used in number theory the most. I could even say that it is basically linear algebra for number theory. So study hard if you were interested in number theory.

>the_quintic_problem Therefore an equation of degree n has general solutions if and only if Sn is solvable. And since Sn is a finite group, it means whether Sn has a composition series in which all factor groups are Zp. This corresponds to that by adding the primitive p-th root of unity, you can extend the base field to the field that factorizes the polynomial. But for n>4, An is simple so that Sn is not solvable.

I've just started learning Esperanto!
Very excited to hear that!
