Psi(x) = Sumationn CnPhin(x)
in order to find Cn, i have to multiply both side of the above equation by Phi*k(x) and take the integral. The result is Ck if n = k. My question is what is the value of Phi*k(x)?
i know that multiplying both side of the equation by Phi*k(x) would make the...
can you explain this statement "if psi is a solution of a schrodinger equation, then so is kpsi, where k is any constant".
why is that multplying psi by a constant does not its value?
