The exact solutions of fuzzy wave-like equations with variable coefficients by a variational iteration method

In present paper, the same strategy as Buckley–Feuring by the variational iteration method are used for find exact fuzzy solution of the fuzzy wave-like equations in one and two dimensions. Several examples are given to show the Buckley–Feuring solution and the Seikkala solution. The results show that the variational iteration method, without linearization or small perturbation, is very effective and convenient.
