In this paper, we presented the Raabe's integral and Hermite's formula for q-gamma function Gamma(q)(x), 0 < q < 1. We deduced new proofs of the formulas Gamma(q)'(x)/Gamma(q)(x) and q-Gauss's multiplication using the Hermite's formula of Gamma(q)(x) and H. Jack's ...
is calculated by means of this formula, the relative error is less thanewln–1 and thus approaches 0 asnincreases without bound. Whenn= 10, for example, the formula yieldsn!= 3,598,700, whereas the exact value of 10! is 3,628,800. In this case, the relative error is less than 1...

Abstract Inspired by a formula of C. Mortici for approximation to Γ(n+1), we establish a class of asymptotic expansions for the gamma function. Based on these expansions, we present new upper and lower bounds for the gamma function.

Cauchy’s Integral for FunctionsC是简单闭合曲线(逆时针),函数f(z)在C以及其包围的区域内均为解析(连续可导),z0是区域内一点,则有 f(z0)=12πi∫Cf(z)z−z0dz 即如果已知在边界C上函数值f(z),意味着边界内任意点对应的函数值f(z0)已知。
1. Using gamma function,the paper popularized the common conceptions of the usual factorial,permutation and combination and proved some combination formulas in common use. 依照伽马函数,对通常的阶乘、排列、组合的概念进行了推广,并证明了一些常用的组合公式。
