Qiu, Yigui; Cai, Ping Numerical verification and error analysis of asymptotic solutions of strongly nonlinear oscillation. (Chinese. English summary) Zbl 1117.65342 J. Zhangzhou Teach. Coll., Nat. Sci. 19, No. 4, 31-36 (2006). Summary: The multiple scales method of G. E. Kuzmak [Prikl. Math. Mekh. 23, 515–526 (1959; Zbl 0089.29803)] and of J. C. Luke [Proc. R. Soc. Lond., Ser. A 292, 403–412 (1966; Zbl 0143.13603)] can be efficiently applied to obtain the solutions of strongly nonlinear oscillators with slowly varying parameters. A technique of numerical order verification is applied to verify that the asymptotic solutions are uniformly valid for small parameter. A numerical comparison of error shows that the asymptotic solutions obtained by the multiple scales method of Kuzmak-Luke [loc. cit.] are uniformly valid, and the errors are about one-tenth of the small parameter \({\varepsilon}\).
