Comparative Dynamical Analysis of the Ratchet Potential with a Lagrange Polynomially Approximated Value by Usman A. Marte, Uchechukwu E. Vincent, Abdulahi N. Njah (pages 17-20)
Sale price: $5.00


The ratchet potential gradient (PG) was approximated using Lagrange interpolation, to obtain a (a) Third degree polynomial (b) A fourth degree polynomial (c) A fifth degree Polynomial and (d) A tenth degree polynomial. These polynomials were used to obtain the attractors and time history, and the results were compared with attractor and the time series plot (TS) of the exact potential gradient.
