In the paper under review, the authors obtain non-standard Lagrangians for some Liénard-type equations. For the proof, the authors use generalized Sundman transformations to transform the equations into either damped harmonic oscillator or of the Painlevé-Gambiér type, which admits non-standard Lagrangians.
