Deriving the formula for the normal distribution (exponential derivative)
I'm trying to get my head around the formula for the normal distribution:
Should be a normalising constant so that the area below the curve is always equal to 1. If I am not mistaken, this normalising constant is the derivative of the exponential term. I've looked at the rules for taking derivatives and seem to be unable to get this as an answer for the derivative of the exponential.
In specific, I fail to see where the square root and pi come from..
I was hoping someone here could give me a clue. Many thanks in advance!
Can anyone give me
