Part: Discrete Calculus and Difference Equations
This part is dedicated to the so-called discrete calculus, sometimes also called the calculus of finite differences. This is a subject providing methods for solving difference equations. As opposed to differential equations, difference equations are useful as a mathematical representation for certain physical problems.
The purpose of this part is to develop a calculus of "differences" and a "sums", in analogy to the calculus of
derivatives and Riemann integrals.
