Chapter 10, Problem 10.23E

The uncertainty principle is related to the order of the two operators operating on a wavefunction. Evaluate the expressions

$\text{<mover accent="true"> x <mo> ^ </mo> </mover>}\left(\widehat{p_{\text{x}}}\sin \pi \text{x}\right)$ and $\widehat{p_{\text{x}}}\left(\text{<mover accent="true"> x <mo> ^ </mo> </mover>}\sin \pi \text{x}\right)$ and demonstrate that you get different results.
