This paper is concerned with the existence and uniqueness of a strong solution for linear problem by using a functional analysis method, which is based on an energy inequality and the density of the range of the operator generated by the problem. Applying an iterative process based on results obtained from the linear problem, we prove the existence and
uniqueness of the weak generalized solution of nonlinear hyperbolic Goursat problem with integral condition.
