This paper deals with the construction of continuous numerical solutions of mixed problems described by the time-dependent telegraph equation u"t"t + c(t)u"t + b(t)u = a(t)u"x"x, 0 0. Here a(t), b(t), andc(t) are positive functions with appropiate additional alternative hypotheses. First, using the separation of variables technique a theoretical series solution is obtained. Then, after truncation using one-step matrix methods and interpolating functions, a continuous numerical solution with a prefixed accuracy in a bounded subdomain is constructed.
