This paper considers the computational solution of some first order delay differential equations (DDEs) using a class seventh Hybrid Extended Block Adams Moulton Methods (HEBAMM) without application interpolation techniques in evaluating term. The term was evaluated by valid expression sequence. By matrix inversion techniques, discrete schemes proposed method were obtained through its continuou...

Abstract Interior modeling of Jupiter and Saturn has advanced to a state where thousands models are generated that cover the uncertainty space many parameters. This approach demands fast method computing their gravity field shape. Moreover, Cassini mission at ongoing Juno delivered gravitational harmonics up J 12 . Here we report expansion theory figures, which is for shape computation, seventh...
