i don't understand..
i am so sorry..
i know how to get Ψ1(x), Ψ2(x) and Ψ3(x) by simply substituting n = 1, 2, or 3 into the wavefunction equation.
what do you mean by inner product? dot product?
but i don't know how to continue from here.
thanks a lot for your help.
1. PROBLEM
Q: write down an expression for a superposition wavefunction \Psi(x) for an electron in a 1D box of length L consisting of the n = 1, 2, and 3 states. show that C12 + C22 + C32 = 1, and Cn represents the coefficients of the n state.
