I am confused as to where the function for the normal distribtuion comes from. Where does the e and pi come from? In my textbook I am presented with the function,but I am unsure about where it came from. I have spent hours on google and have yet to find a good proof that i can understand. Come someone provide a source that shows an elementary proof of the normal curve function.

    Where the function comes from. (1/s sqrt(2pi))e^(-x^2/(2s^2))2012-10-21
