The laws of nature are expressed as differential and difference equations. Scientists 

and engineers must know how to model the world in terms of differential and 

difference equations, and how to solve those equations and interpret the solutions. 

A differential equation is an equation that defines a relation between a function and 

its derivatives. In this course we learn how to solve the basic types of differential 

and difference equations by elementary methods and to use them at applications in 

science and engineering. The study of the course continues the formation of 

students' general mathematical foundations to navigate them as future 

professionals in the flow of scientific and technical information and providing 

them the opportunity to use differential and difference equations in their 

professional activities.
