Natural Logarithm - Continued Fractions

Continued Fractions

While no simple continued fractions are available, several generalized continued fractions are, including:


\ln (1+x)=\frac{x^1}{1}-\frac{x^2}{2}+\frac{x^3}{3}-\frac{x^4}{4}+\frac{x^5}{5}-\cdots=
\cfrac{x}{1-0x+\cfrac{1^2x}{2-1x+\cfrac{2^2x}{3-2x+\cfrac{3^2x}{4-3x+\cfrac{4^2x}{5-4x+\ddots}}}}}

\ln \left( 1+\frac{2x}{y} \right) = \cfrac{2x} {y+\cfrac{x} {1+\cfrac{x} {3y+\cfrac{2x} {1+\cfrac{2x} {5y+\cfrac{3x} {1+\ddots}}}}}}
= \cfrac{2x} {y+x-\cfrac{(1x)^2} {3(y+x)-\cfrac{(2x)^2} {5(y+x)-\cfrac{(3x)^2} {7(y+x)-\ddots}}}}

Famous quotes containing the word continued:

    The problems of society will also be the problems of the predominant language of that society. It is the carrier of its perceptions, its attitudes, and its goals, for through it, the speakers absorb entrenched attitudes. The guilt of English then must be recognized and appreciated before its continued use can be advocated.
    Njabulo Ndebele (b. 1948)
