### PERIODIC SOLUTION TO GENERAL CONDUCTION PROBLEMS

**ABSTRACT**

In this paper, we present a modified exp-function method, where hyperbolic cosine and cosine functions are used. The hyperbolic cosine functions are responsible for energy localization while cosine functions reveal the periodic effect. A general conduction problem is used as an example to illustrate the solution process.
