“…Homptopy perturbation method was first proposed by the Chinese mathematician He [16][17][18][19][20]. This method has been employed to solve a large variety of linear and nonlinear problems such as fractional partial differential equations [32], the nonlinear HirotaSatsuma coupled KdV partial differential equation [12], nonlinear boundary value problems [22], traveling wave solutions of nonlinear wave equations [21], Nonlinear convective-radiative cooling equation, nonlinear heat equation (porous media equation) and nonlinear heat equation with cubic nonlinearity [13], the Newton-like iteration methods for solving non-linear equations or improving the existing iteration methods [9], evaluating the efficiency of straight fins with temperature-dependent thermal conductivity and determining the temperature distribution within the fin [26], the inverse parabolic equations and computing an unknown time-dependent parameter [28], finding improved approximate solutions to conservative truly nonlinear oscillators [4], complicated integrals which cannot be expressed in terms of elementary functions or analytical formulae [10] and etc.…”
