In the 18th century, figures such as Leonhard Euler and Joseph-Louis Lagrange further advanced the field by providing systematic methods for solving ODEs. The 19th century saw the emergence of more rigorous mathematical frameworks, including the introduction of linear differential equations and the theory of existence and uniqueness of solutions. Throughout the 20th century, ODEs became essential in various scientific fields, leading to modern applications in physics, engineering, and biology.

In differential equations, the complementary solution (or homogeneous solution) is the solution to the associated homogeneous equation, which is obtained by setting the non-homogeneous part to zero. It represents the general behavior of the system without any external forcing or input. The complementary solution is typically found using methods such as characteristic equations for linear differential equations. It is a crucial component, as the general solution of the differential equation combines both the complementary solution and a particular solution that accounts for any non-homogeneous terms.
