We have for example: <x2> = <x>2+s2 <x4> - <x2>2 ≈ 4s2<x>2 (to first order) Now combining both equations yields: <x4> = <x>4+6s2<x>2 Unfortunately this doesn't work that easily for <x6>

Sorry, I forgot to mention. It's a first order Taylor approximation. Thanks for the reply, Cheers

Hello everybody, I'm looking for a proof of the following equation: <x6> = <x>6+15s2<x>4 where the brackets denote an expectationvalue and s is the standard deviation. Thanks in advance!
