Simple Equations Method for Obtaining Exact Solutions of Nonlinear Differential Equations with Polynomial or Nonpolynomial Nonlinearity
摘要
We discuss the Simple Equations Method for obtaining exact solutions of non-linear differential equations. We demonstrate the methodology on the basis of two examples. In the first example we show the effect of a transformation on an equation possessing nonpolynomial nonlinearity. The equation is transformed to an equations with a polynomial nonlinearity which can be solved by Jacobi elliptic functions. In the second example we obtain a solution of an equation which possesses polynomial nonlinearity.
