1. The problem statement, all variables and given/known data Hey guys. Basically I have a wavefunction that looks like this http://imageshack.com/a/img843/3691/22r3.jpg [Broken] I have to find: (a) The normalization constant N, of course by normalizing it (b) Find <x> and <x^2> and use this to find Δx. 2. Relevant equations I'm just gona insert images, as i'm writing it all with my tablet: http://imageshack.com/a/img33/5705/czbs.jpg [Broken] 3. The attempt at a solution Okay, so I've found the normalization constant, N, but I've got 2 different answers depending on the way in which I solve the problem, and I want to know which is correct (and why, if possible). Please view the image below: http://imageshack.com/a/img11/7232/0hmb.jpg [Broken] So...which is correct? :S I need to know the explicit expression for the probability density to proceed further. Thanks a lot guys!
