ca.analysis and odes - How many ways can we characterize gamma function?

maybe I can give you some help.
Gamma function is also called the second Euler integral.



Here comes some characterizations.



a f(s)= t(x)=int+infty0t(s1)exp(t)dt

s>0



b f(s)=limn!ns/[s(s+1)...(s+n)]

nrightarrow+infty



c Bpq=Gamma(p)Gamma(q)/Gamma(pq

p>0 q>0



d Gamma(2s)=2(2s1Gamma(s)Gamma(s+1/2)/sqrt(2pi)

s>0



e Gamma(s)Gamma(1s)=pi/sin(spi)

0

May it help!
