Question

Integration help!!!

Answer 1

\(\Psi = \sqrt{\dfrac 2 L} sin{(\dfrac {2\pi x}{L})}\) for 0\(\le\)x\(\le\) L.
Determine the expectation value.


The expectation value <x> is calculated as
\[<x> = \int_{-\infty}^{+\infty} \Psi^* x \Psi dx\] where \(\Psi^*\) is the complex conjugate of \(\Psi\). Anyone know how to do the calculation?

Answer 2

@roadjester seems u are doing one dimensional potential well problem

Answer 3

Indeed, except no one wants to help in physics and this IS integration which is calculus.

Answer 4

Unless you want to help me with the full problem? I'll post it in the physics group

Answer 5

yeah i will try to help u out
