Iterative Methods for Nonlinear Equations

Two novel identities arising from the second- and thirdorder derivatives of the reciprocal radial distance and involving delta functions are introduced, proven, and illustrated. A general procedure is described for establishing similar identities for higher-order derivatives of the reciprocal radial distance.
