The limit cycles of these systems are studied by applying the homotopy analysis method (HAM). The amplitude and frequency obtained with this methodology are in good agreement with those calculated by computational methods. This puts in evidence that HAM is a useful tool to solve nonlinear differential equations. 000171149 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc$$uhttps://creativecommons.org/licenses/by-nc/4.0/deed.es 000171149 590__ $$a0.499$$b2011 000171149 591__ $$aMATHEMATICS, APPLIED$$b179 / 245 = 0.731$$c2011$$dQ3$$eT3 000171149 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000171149 700__ $$aLopez, J.
