Differential equations find a wide range of applications in various fields of mathematics, science, and engineering. In the real world, differential equations are used to model and solve complex problems that involve change and variability over time. Of particular interest are ordinary differential equations (ODEs) that describe the behavior of a system at a given point in time.

How to write differential equations?
To write a differential equation, one must first identify the dependent and independent variables and any terms containing derivatives. The equation should be written in the form:
d^n y/dx^n = f(x,y, dy/dx, d^2y/dx^2, ..., d^(n-1)y/dx^(n-1))
where n is the order of the differential equation and f(x,y, dy/dx, d^2y/dx^2, ..., d^(n-1)y/dx^(n-1)) is some function of the variables.
It is important to specify the order and degree of the differential equation, which can be determined by the highest derivative and degree of the equation, respectively.
Once the differential equation is written, it can be solved using various methods such as separation of variables, integrating factors, or using Laplace transforms.

The general solution to a differential equation is a family of functions that satisfies the differential equation, and includes all possible specific solutions by introducing arbitrary constants. Specifically, the general solution of a first-order differential equation can be expressed as an integral involving one arbitrary constant, the general solution of a second-order differential equation can be expressed as a linear combination of two specific solutions with two arbitrary constants, and so on. This general solution represents an m-parameter group of curves, satisfying the differential equation, and can be used to find the particular solution for any given set of initial or boundary conditions.
How to classify differential equations?
Differential equations can be classified as Ordinary Differential Equations (ODEs) or Partial Differential Equations (PDEs).
