Abstract

In this paper, we use theta-function identities involving parameters &#x1D459;<sub>5,n</sub>, &#x1D459;'<sub>5,n</sub>, and &#x1D459;'<sub>5,4n</sub> to evaluate the Rogers-Ramanujan continued fractions <TEX>$R(e^{-2{\pi}{\sqrt{n/20}}})$</TEX> and <TEX>$S(e^{-{\pi}{\sqrt{n/5}}})$</TEX> for some positive rational numbers n.
