A fast insight into the nonlinear oscillators with coordinate-dependent mass
The nonlinear oscillators with coordinate dependent mass is studied by Ren (Results in Physics, 2018(11):1052–1053) and Wu (Results in Physics, 2018(10):270–271) respectively. In this letter, He’s frequency-amplitude formulation combined with the average residuals is used to study this problem. The...
