quantum expectation values
1. The problem statement, all variables and given/known data
Consider a particle in an infinite one-dimensional box that has a length L and is centered at the origin. (Use h for Planck's constant, n, and L, as necessary.) Evaluate <x^2> for <x^2> at n=1.
2. Relevant equations
3. The attempt at a solution
I used this formula and got the answer (L^2/12)+(L^2/(2*pi^2)). My assignment is telling me this is incorrect. I took the same approach for the second part of my homework asking for this when n=2, and I got (L^2/12)-(L^2/(8*pi^2)) which it says is correct. I cannot figure out why my first answer is not correct as well. Any help would be much appreciated.

Sorry. Just figured it out.
