All of the Partial Differential Equation course into 5 chapters, where in each sub-chapter an example is given and at the end of each chapter is given practice questions in the hope that students can further develop their applications In addition. This book is also enriched with examples of applications whose visualization uses application programs such as Maple and MATLAB.

In the introductory chapter, the terms commonly used in partial differential equations are introduced, which are then continued by the next chapter with first-order linear partial differential equations. The concept of constructing partial differential equations with the elimination of any function and the elimination of any constant is presented in chapter 3 followed by nonlinear equations and their solution techniques. Next is the topic of the 2^nd order linear partial differential equation with constant coefficients in chapter 5. It ends with the issue of the Initial condition and boundary conditional outlined in chapter 6. It is hoped that students can learn more about the application of Partial Differential Equations in daily life.

          Hopefully the description in this book can help students in understanding and applying differential equations, especially partial differential equations as a tool in mathematical modelling and expressing the natural phenomena, either in the field of engineering, mathematics or in general in the field of mathematical applications in daily life.
