Analytic solution for Telegraph equation by differential transform method

In this article differential transform method (DTM) is considered to solve Telegraph equation. This method is a powerful tool for solving large amount of problems (Zhou (1986) 1], Chen and Ho (1999) 2], Jang et al. (2001) 3], Kangalgil and Ayaz (2009) 4], Ravi Kanth and Aruna (2009) 5], Arikoglu and Ozkol (2007) 6]). Using differential transform method, it is possible to find the exact solution or a closed approximate solution of an equation. To illustrate the ability and reliability of the method some examples are provided. The results reveal that the method is very effective and simple.
