I have an answer to a question not yet asked. "Relatively Prime" does not mean it is "sort-of, more-or-less, kinda Prime", it means that two numbers have no common factors (except 1 or -1) - in other words if they were a fraction they couldn't be simplified further.

Now the general:

1.Elliptic curve:

It wasn't so hard.

Let have a cartesian plane with coordinates xOy.

The following equation is given:

If it's "true" we plot (x,y). Otherwase, we don't plot it.

Here's a plot of elliptic curve(picture 1).

Because the equation was 2 roots:y=sqrt(...) and y=-sqrt(...) the elliptic curve is a Riemann surface.

Now I should understand why every elliptic curve is Riemann surface with geus 1.
