Linear Differential Equations

Linear Differential Equations are differential equations where the unknown function and its derivatives appear linearly. In other words, the equation is a linear combination of the function and its derivative, with constant coefficients. Such types of equations have solutions that can be expressed as a sum of particular and homogeneous solutions.

In this article, we will discuss all things linear differential equations, including their order, type, solutions, and applications in various fields of mathematics and science.
