A bound for the error between the expectation value of a self-adjoint operator B on the eigenfunction of a self -adjoint Hamiltonian H and the value given by an approximating vector, is obtained when H is a radial Schrodinger operator and B is multiplicative and unbounded. The analysis makes use of point and asymptotic estimates for the eigenfunction.
