SUMMARY

The discussion focuses on proving the identities \(\Gamma\left(\frac{1}{2}\right) = \sqrt{\pi}\) and \(\Gamma\left(\frac{3}{2}\right) = \frac{\sqrt{\pi}}{2}\). The first part is established through substitution and conversion to polar coordinates. The second part utilizes the property \(\Gamma(x+1) = x \Gamma(x)\) to derive the result without needing to repeat the entire proof process.

PREREQUISITES
  • Understanding of the Gamma function and its properties
  • Knowledge of polar coordinates and their application in integration
  • Familiarity with substitution techniques in calculus
  • Basic concepts of mathematical proofs and identities
NEXT STEPS
  • Study the derivation of the Gamma function and its relation to factorials
  • Learn about the properties of the Gamma function, including \(\Gamma(x+1) = x \Gamma(x)\)
  • Explore the application of polar coordinates in multiple integrals
  • Investigate other special values of the Gamma function
USEFUL FOR

Students of mathematics, particularly those studying calculus and special functions, as well as educators looking to enhance their understanding of the Gamma function and its applications.

Homework Statement



Prove \Gamma(1/2) = \sqrt{\pi}

hence proove \Gamma(3/2) = (\sqrt{\pi})/2

solution

i have proved the first part by using sustitution and changing to polar co ords.
To prove the the second part i guess i don't have to work it all out again. i know that \Gamma(x+1) = x \Gamma(x) but i can't this to help me...
