This document provides an introduction and overview of differential equations including:
- It defines differential equations as equations that relate an unknown function to its derivatives.
- It classifies differential equations as ordinary or partial, and discusses homogeneous differential equations which can be solved using separation of variables.
- It provides examples of linear differential equations and discusses their applications in areas like software development, modeling natural phenomena, and theories.
- In conclusion, it states that differential equations are essential for both engineers and non-engineers as they underpin many software programs and describe the natural world.
