To approximate the frequency-amplitude relationship of the singular oscillator, reproducing kernel method is employed. The approximate solution is compared with the exact solution as well as the results obtained by the He's frequency-amplitude formulation, to show the effectiveness of the proposed technique for solving the problem.eninfo:eu-repo/semantics/openAccessFrequency-amplitude relationshipnonlinear singular oscillatorreproducing kernel methodArticle40313631372Q2WOS:000681029400001Q12-s2.0-8509850614910.1177/1461348420980539
