C# Spiral - component

Hello :-)

I'm doing a spiral in c# to make a component after.

I'm not very good yet at coding in grasshopper, but I'm giving lot of passion to reach an acceptable level.
My coding background is on Unity, and its quiet different.

Anyways, I think this little exercice its a child's play for some of you.

The idea its to make the component more robust.
First I'm doing it in Rhino and then I will make a component with that spiral.

I writed annotations around in the grasshopper file.
It will be lot easier to understand than a text here.

Its quiet funny because, I didn't find any spiral with C#/Vb/Python here.
Then I can propose that one I guess !
I hope I'll find some fixes, let see.

Hope you'll be interrested to play also ^^.

The code :

    Point3d newCoord = new Point3d();


    newCoord = P;

    IEnumerable < double > squares = Enumerable.Range(start, end).Select(x => ( (P.X) + ((((((D / N) * x)) * Math.Cos(((D / N) * x)))) * factor)));
    IEnumerable < double > squares1 = Enumerable.Range(start, end).Select(x => ((P.Y) + ((((D / N) * x)) * Math.Sin(((D / N) * x)))) * factor);


    foreach (double num in squares)
    {
      //Print(num.ToString());
      xPoints = squares;
    }

    foreach (double num1 in squares1)
    {
      //Print(num1.ToString());
      yPoints = squares1;
    }

    foreach (double num1 in squares1)
    {
      //Print(num1.ToString());
      zPoints = newCoord.Z;
    }
