Abstract
Extended F-expansion method is proposed to seek exact solutions of the Zhiber-Shabat (ZS) equation. As a result, many new and more general exact solutions are obtained. Interesting Jacobi doubly periodic wave solutions is obtained from the F-expansion (EFE) method with symbolic computation. It is shown that soliton solutions and triangular periodic solutions can be established as the limits of Jacobi doubly periodic wave solutions. In addition, as an illustrative sample, the properties for the Jacobi doubly periodic wave solutions of theses equations are shown with some figures. [Bhrawy AH, Obaid M.
