  2. Continued fraction - Wikipedia

    en.wikipedia.org/wiki/Continued_fraction

    Another meaning for generalized continued fraction is a generalization to higher dimensions. For example, there is a close relationship between the simple continued fraction in canonical form for the irrational real number α, and the way lattice points in two dimensions lie to either side of the line y = αx. Generalizing this idea, one might ...

  3. Euler's continued fraction formula - Wikipedia

    en.wikipedia.org/wiki/Euler's_continued_fraction...

    Euler derived the formula as connecting a finite sum of products with a finite continued fraction. (+ (+ (+))) = + + + + = + + + +The identity is easily established by induction on n, and is therefore applicable in the limit: if the expression on the left is extended to represent a convergent infinite series, the expression on the right can also be extended to represent a convergent infinite ...

  4. Periodic continued fraction - Wikipedia

    en.wikipedia.org/wiki/Periodic_continued_fraction

    By considering the complete quotients of periodic continued fractions, Euler was able to prove that if x is a regular periodic continued fraction, then x is a quadratic irrational number. The proof is straightforward. From the fraction itself, one can construct the quadratic equation with integral coefficients that x must satisfy.

  5. Simple continued fraction - Wikipedia

    en.wikipedia.org/wiki/Simple_continued_fraction

    A simple or regular continued fraction is a continued fraction with numerators all equal one, and denominators built from a sequence {} of integer numbers. The sequence can be finite or infinite, resulting in a finite (or terminated ) continued fraction like

  6. Solving quadratic equations with continued fractions - Wikipedia

    en.wikipedia.org/wiki/Solving_quadratic...

    If this infinite continued fraction converges at all, it must converge to one of the roots of the monic polynomial x 2 + bx + c = 0. Unfortunately, this particular continued fraction does not converge to a finite number in every case. We can easily see that this is so by considering the quadratic formula and a monic polynomial with real ...

  7. Gauss's continued fraction - Wikipedia

    en.wikipedia.org/wiki/Gauss's_continued_fraction

    The continued fractions on the right hand side will converge uniformly on any closed and bounded set that contains no poles of this function. [7] In the case , the radius of convergence of the series is 1 and the fraction on the left hand side is a meromorphic function within this circle. The continued fractions on the right hand side will ...

  8. Rogers–Ramanujan continued fraction - Wikipedia

    en.wikipedia.org/wiki/Rogers–Ramanujan...

    The Rogers–Ramanujan continued fraction is a continued fraction discovered by Rogers (1894) and independently by Srinivasa Ramanujan, and closely related to the Rogers–Ramanujan identities. It can be evaluated explicitly for a broad class of values of its argument.

  9. Chain sequence - Wikipedia

    en.wikipedia.org/wiki/Chain_sequence

    Since f(x) = x − x 2 is a maximum when x = ⁠ 1 / 2 ⁠, this example is the "biggest" chain sequence that can be generated with a single generating element; or, more precisely, if {g n} = {x}, and x < ⁠ 1 / 2 ⁠, the resulting sequence {a n} will be an endless repetition of a real number y that is less than ⁠ 1 / 4 ⁠.
