A note on the method of multiple scales [PDF]

open access: yesQuarterly of Applied Mathematics, 1980
A modification of the method of multiple scales makes use of the expansion of parameters of the system in order to remove undesirable characteristics of the solution obtained by the usual multiple-scale method. When applied to the damped harmonic oscillator, the modification leads to the exact solution.
