Continued fraction of root 2

WebTo answer the question about patterns in the continued fractions of other numbers: to the best of my knowledge, nothing is known about the continued fractions of e.g. cube roots — not even whether their coefficients are bounded! — though it's known that they can't grow too quickly: this is a corollary of Roth's Theorem, which bounds the so ... Webthe regular continued fraction x is said to be purely periodic. For example, the regular continued fraction for the golden ratio φ – given by [1; 1, 1, 1, ...] – is purely periodic, while the regular continued fraction for the square root of two – [1; 2, 2, 2, ...] – is periodic, but not purely periodic.
