“…Many linear and nonlinear phenomena appear in several areas of scientific fields like physics, chemistry and biology can be modeled by different type of partial differential equation [1][2][3][4]. A broad class of analytical methods and numerical methods have been introduced such as (G′/G)-expansion method [5], Exp-function method [6], Homotopy perturbation method [7], Homotopy analysis method [8], Laplace transform [9], Residual power series [10], Quasi wavelet method [11], Fourier series [12], Chebyshev-Tau method [13], Haar wavelets method [14], trial equation method [15] and Two scale approach [16] to handle these linear and nonlinear PDEs but to reach exact solutions is not an easy way. In past few decades, The Klein-Gordon and sine-Gordon equations are a type of hyperbolic partial differential equation which are often used to describe and simulate the physical phenomena in a variety of fields of engineering and science, i.e., physics, fluid dynamics, mathematical biology and quantum mechanics.…”
