SUMMARY

The discussion focuses on calculating the ratio of gamma functions, specifically \(\Gamma(7/3)/\Gamma(1/3)\). The key property utilized is \(\Gamma(z + 1) = z\Gamma(z)\), which simplifies the calculation by expressing \(\Gamma(7/3)\) in terms of \(\Gamma(4/3)\). This approach allows for a more manageable computation without resorting to first principles, demonstrating the utility of gamma function properties in solving complex problems.

PREREQUISITES
  • Understanding of gamma functions and their properties

Hi, I need to calculate \Gamma(7/3)/\Gamma(1/3)
is there some trick to doing this type of problem? I'm finding it really hard to do from first principles.
Any help would be great, thanks!
