A brief exploration of the Lambert W function is presented in this article. Firstly, the basic information and history perspective of this function are reviewed. The calculus and examples are introduced accordingly. At the end, this function is applied to solving transcendental equations and delay equations as well as to computing the period of periodical solution to a Lokta-Volterra system for the predator-pray model. We hope the reader can get acquainted with the Lambert W function and its applications.
