SUMMARY
The Gamma function is defined as Gamma(z) = ∫(0 to ∞) t^(z-1)e^(-t) dt. In this integral, 't' serves as the variable of integration, while 'z' is a parameter that determines the shape of the function. The integrand f(z,t) = t^(z-1)e^(-t) is a function of both 'z' and 't', but upon integration over the t-domain, the result is solely a function of 'z'. This understanding clarifies the relationship between the variables in the Gamma function.
