摘要:

应用beta积分加速超几何函数$2 F 1\left\{1, B; C ; w\right\}$,以推导常数(如$π$)及Gamma函数值的新无穷级数。文中给出了新无穷级数的汇编。基于初等反三角函数推导了类Ramanujan的pi公式,包括一个有理值公式,每项增加2.5位数字,使该级数比现有文献中的类似公式更紧凑。

英文摘要:

The beta integral is applied to accelerate the hypergeometric function $2 F 1\left\{1, B; C ; w\right\}$ to derive new infinite series for constants such as $π$ and values of the gamma function. A compendium of new infinite series is given. Ramanujan-like formulas for pi are also derived based on elementary inverse trigonometric functions, including a formula with rational values that adds 2.5 digits per terms, which makes the series much more compact than similar formulas in the existing literature.
