Moreover, traveling wave hypothesis is used to obtain sech solution of type II coupled KdV system, in a more general setting. The results show that this method presents exact solutions compared with other methods and it is a powerful tool for solving systems of nonlinear PDEs. %U https://ijsts.shirazu.ac.ir/article_1500_b1de5bfa94c97202cecf6de98fec73a4.pdf
