Higher-order approximate solutions to the relativistic and Duffing-harmonic oscillators by modified He's homotopy methods
A modified He's homotopy perturbation method is used to calculate higher-order analytical approximate solutions to the relativistic and Duffing-harmonic oscillators.The He's homotopy perturbation method is modified by truncating the infinite series corresponding to the first order approximate solution before introducing this solution in the second order linear differential equation, and …
