Hi I have been working my way through some past papers and then checking the solutions but I am confused about the following. One question asked for the normalisation constant for the following wavefunction ψ( r, θ , ø ) = Aexp(-r/R) where R is a constant. The solution requires a triple volume integral using dV=r^2sinθdrdθdø. The 2nd question asks to normalise exp(imø) but this time the integral is just done over dø from 0 to 2∏. The 1st wavefunction only involves r but I have to do a triple integral. The 2nd only involves ø but I just need a single integral. I'm confused !
