First post and not used to the symbols that I have seen used in posting formulae, so please be patient!(adsbygoogle = window.adsbygoogle || []).push({});

The probability of obtaining theith energy eigenvalue Eiis given by the square modulus of the integral psi_i*(x)PSI(x,t)dx where PSI(x,t) is the wave function of the system.

How can this be calculated since the wavefunction is a product of the superposition of all the possible energy eigenfunctions, psi_i(x)? I guess what I am trying to ask is - how can we know PSI(x,t)? Every text I have read typically starts problems in this area with "Suppose we have a wavefunction,...."

Thanks to all that help
