1. The problem statement, all variables and given/known data I need to square the magnitude of psi for each of my integrals 2. Relevant equations for x between 0 and a, [tex]\psi(x,0)[/tex] = A(x/a), where A and a are constants 3. The attempt at a solution So I take A(x/a) and square it since it is already positive. so [tex]A^2\ast(x^2/a^2)[/tex] . . but in the proof of my book, it makes use of the complex conjugate, which I am sure of how that fits for my particular psi function . . which makes me think that [tex]A^2\ast(x^2/a^2)[/tex] is not correct so is [tex]|\psi|^2[/tex] = [tex]A^2\ast(x^2/a^2)[/tex] if [tex]\psi[/tex] = A(x/a) in this example?
