Frequency and solution of an oscillator with a damping
The frequency is an intrinsic mathematical index for a nonlinear oscillator. The variational iteration method and He’s frequency formulation are used to handle the special oscillator x ¨ + ( 1 + x ˙ 2 ) x = 0 for its approximate frequency and solutions. The Laplace transform and Ren–Hu’s average res...
