Hi, In the gamma function (shown below), what does "t" stand for? $\displaystyle \Gamma(z)=\int_{0}^{\infty}t^{z-1}e^{-t}$

Ah, so is this what you call an "implicit function?" Both the x and y variable (in this case z and t) being involved in the right side of the equation? Pardon my ignorance if this sounds really ignorant.

Thanks. I guess my basic question is how do I enter the function into my grapher so as to get the famous gamma function graph. Still no luck with this.
