Lecture 28: Normal Distribution of a Random Variable (Part 1)

[@anshikagoel4809]

Can you please provide a video to prove that the pdf of normal distribution is equal to 1

@anshikagoel4809 okay.. Meanwhile try to do this: Substitute x- mu/ sigma = Z, you get standard normal distribution then Substitute z^2/2= t and you get gamma function. You get Gamma(1/2) which is nothing but root(pi). Ultimately you get 1.

Can u show the derivation of the pdf of normal distribution. Thankzz

[@DrMathaholic]

Derivation of pdf🤔🤔🤔 Well, it was De moivre/ Gauss who came up with this nice function..and when u plot u get a bell shaped curve...
