I've never seen an expectation value taken and would greatly appreciate seeing a step by step of how it is done. Feel free to use any wavefunction, this is the one I've been trying to do:(adsbygoogle = window.adsbygoogle || []).push({});

In the case of [tex]\Psi=c[/tex]_{1}[tex]\Psi[/tex]_{1}[tex] + c[/tex]_{2}[tex]\Psi[/tex]_{2}[tex] + ... + c[/tex]_{n}[tex]\Psi[/tex]_{n}

And theoperatorA(hat) => A(hat)[tex]\Psi[/tex]_{1}= a_{1}[tex]\Psi[/tex]_{1}; A(hat)[tex]\Psi[/tex]_{2}= a_{2}[tex]\Psi[/tex]_{2}; A(hat)[tex]\Psi[/tex]_{n}= a_{n}[tex]\Psi[/tex]_{n}

Calculate: [tex]\left\langle\Psi\left|A(hat)\right|\right\Psi\rangle[/tex]
