(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A particle with massmis trapped inside the infinite potential well:

0<x<L : U(x) = 0

otherwise: U(x) = ∞

ψ(x,t=0) = Ksin(3∏x/L)cos(∏x/L)

What energies can be measured from this system, what are the probabilities for these energies ?

2. Relevant equations

Schrödinger equation, |ψ(x,t)|^2 = 1

3. The attempt at a solution

I can solve this type of problem normally when ψ = Asin(...) + Bcos(...), but the look of the ψ function confuses me. My guess i should use the Schrödinger equation to give me E like normally.. but maybe that's not how im supposed to do this. If it is, my math skills are not good enough. I've been trying quite hard to get something good out of (d/dx)^2(ψ) / ψ .

So thanks in advance for any help i can get. :)
