Hello all, I am looking for exact forms (as real number expressions) of the golden ration that are not rewrites of the one we all know and love, i.e.

g.r. = 1/2(5^(1/2)+1)

Searches in Google have yielded nothing so far :P

A good link, but I had already seen it. The trigonometric versions are just substitutions of the same expression, = 1/2(5^(1/2)+1).

I also checked out Wolfram and I noticed this,


which is a wonderful general form!

Anyone else have anything to add?
