In this paper, we consider the class of wave-type equations u,, = f(x, t, u)uxx, + g(x, t, u, ux, u,) and two special cases of it. We derive the equivalence transformations for these equations and using these transformations, we obtain differential invariants and invariant equations. We employ these invariants or/and invariant equations to classify all equations of this general class that can be mapped into a simple linear hyperbolic or into an elliptic equation. Additional applications are presented.
