1. The problem statement, all variables and given/known data

\Delta x_{n}\ Delta P_{n} in the situation of an infinite-square-well potential in the eigenstate |\psi_{n}> of the hamiltonian.

2. Relevant equations

psi(x)=Sqr(2/a) sin( n*Pi x / a) , for n = 1,2,3

3. The attempt at a solution

I need a hint to let me start solving the problem. the problem statement is not clear for me.

Thanks

R

The entire statement is not clear. They are asking to calculate \Delta x_{n}\ Delta P_{n} , This is not clear for me

How does $\Delta x$ come about usually ?
