This article is devoted for the study of new extended hyperbolic function method (EHFM) to attain the exact soliton solutions of the perturbed Boussinesq equation (PBE) and KdV-Caudery-Dodd-Gibbon (KdV-CDG) equation. We can claim that these solutions are new and are not previously presented in the literature. In addition, 2d and 3d graphics are drawn to exhibit the physical behavior of obtained new exact solutions.eninfo:eu-repo/semantics/openAccessperturbed BEKdV-CDG equationEHFMsolitonArticle1111Q2WOS:000727299600001Q22-s2.0-8512283327010.3390/coatings11111429
