Intergration of imcomplete gamma distribution

Click For Summary
SUMMARY

The discussion focuses on determining the integration of the incomplete gamma function, specifically the calculation of int_0^1 gammainc(3/4,r). The incomplete gamma function is defined as gammainc(a,x)=int_0^x t^(a-1)e^(-t) dt. A solution was achieved using Kummer's confluent hypergeometric function, demonstrating its applicability in solving such integrals.

Hey
Do you mean numerical integration or what?
For properties of the incomplete gamma function see http://en.wikipedia.org/wiki/Incomplete_gamma_function"
