چکیده
|
This paper presents a new generalization of the standard homotopy analysisapproach towards solving nonlinear oscillators equations with rational terms. by usingthis method, analytical approximations to the frequency of these oscillators and periodicsolutions are calculated. excellent agreement of the approximate frequencies and periodicsolutions with exact ones is demonstrated and discussed. it is shown that this method isvery simple, e ective and convenient for solving nonlinear oscillator problems with rationalterms.
