Minimum of Normal Distribution Function

  1. Apr 15, 2013 #1
    1. The problem statement, all variables and given/known data

    Show that there is no minimum for the normal distribution function e^(-(x-μ)^2/(2 σ^2))/(sqrt(2 π) σ)

    2. Relevant equations

    3. The attempt at a solution

    I figured I'd take the derivative and set it equal to 0, but then what?

    What is the answer you got? And then, how do you tell the difference between a maximum and a minimum?
