What Is Differential Equation?

A differential equation is a mathematical equation that involves functions and their derivatives. It plays a fundamental role in various areas, such as physics, engineering, economics, and biology.

Understanding the intricacies of differential equations can be challenging, but our differential equation calculator simplifies the process for you. It provides the solution.

What Are the Different Types of Differential Equations?

Different differential equations are classified primarily based on the types of functions involved and the order of the highest derivative present. The primary types include:

• Ordinary Differential Equations (ODEs) include a function of a single variable and its derivatives.

  The general form of a first-order ODE is

  $$F\left(x,y,y^{\prime}\right)=0,$$

  where $$$y^{\prime}$$$ is the first derivative of $$$y$$$ with respect to $$$x$$$.

  An example of a first-order ODE is $$$y^{\prime}+2y=3$$$. The equation relates the function $$$y(x)$$$ to its derivative $$$y^{\prime}$$$ and constants.

• Partial Differential Equations (PDEs). These involve a function of multiple variables and their partial derivatives.

  The general form for a function of two variables is

  $$F\left(x,y,u,u_x,u_y\right)=0,$$

  where $$$u_x$$$ and $$$u_y$$$ are the partial derivatives of $$$u$$$ with respect to $$$x$$$ and $$$y$$$, respectively.

  The heat equation is an example of a PDE:

  $$\frac{\partial u}{\partial t}=k\left(\frac{\partial^2 u}{\partial x^2}+\frac{\partial^2 u}{\partial y^2}+\frac{\partial^2 u}{\partial z^2}\right),$$

  where $$$\frac{\partial u}{\partial t}$$$ is the time derivative, $$$k$$$ is a constant, and $$$\frac{\partial^2 u}{\partial x^2}+\frac{\partial^2 u}{\partial y^2}+\frac{\partial^2 u}{\partial z^2}$$$ is the Laplacian, representing a second-order spatial derivative.

• Linear and Nonlinear Differential Equations: If a DE can be expressed linearly with respect to the unknown function and its derivatives, it's a linear DE.

  An equation is linear if it can be expressed in the following form:

  $$a_n(x)y^{(n)}+a_{n-1}(x)y^{(n-1)}+\ldots+a_1(x)y^{\prime}+a_0(x)y=g(x),$$

  where the coefficients $$$a_i(x)$$$, $$$i=\overline{1,2,..n}$$$, are constants or functions of the independent variable $$$x$$$ but not of $$$y$$$ or its derivatives.

  An example of a linear DE is $$$y^{\prime\prime}-4y^{\prime}+4y=0$$$.

  An example of a nonlinear DE would be $$$y^{\prime\prime}+y^{\prime}y=0$$$.

• Homogeneous and Nonhomogeneous Differential Equations: If $$$g(x)=0$$$, the equation is homogeneous; otherwise, it is nonhomogeneous.

  An example of a homogeneous DE would be $$$y^{\prime}+y^2=0$$$.

  An example of a nonhomogeneous DE is $$$y^{\prime}+4y=3x+5$$$.
