How Does a General Solution Calculator Work?

A General Solution Calculator works by taking a differential equation as an input represented as y = f(x) and calculating the results of the differential equation. Solving a differential equation gives us insight into how quantities change and why this change occurs.

What Are Differential Equations?

A differential equation is an equation that contains the derivative of an unknown function. The derivatives of a function determine how quickly it changes at a given point. These derivatives are connected to the other functions using a differential equation. 

The principal applications of differential equations are used in the sciences of biology, physics, engineering, and many more. The differential equation’s primary goal is to study the solutions that satisfy the equations and the solutions’ characteristics.

Any equation with at least one ordinary or partial derivative of an unknown function is referred to as a differential equation. Assuming that a function’s rate of change about x is inversely proportional to y, we may write it down as $\frac{dy}{dx} = \frac{k}{y}$.

A differential equation in calculus is an equation that involves the dependent variable’s derivatives concerning the independent variable. The derivative is nothing more than a representation of the rate of change

The differential equation aids in presenting a relationship between the changing quantity and the change in another quantity. Let y=f(x) be a function, where f is an unknown function, x is an independent variable, and f is the dependent variable.

What Are Order of Differential Equations?

The order of a differential equation is the order that is determined by the highest order derivative that appears in the equation. Consider the following differential equations:

\[ \frac{dx}{dy} = e^{x} , (\frac{d^{4}x}{dy^{4}}) + y = 0 , (\frac{d^{3}x}{dy^{3}}) + x^{2}(\frac{d^{2}x}{dy^{2}}) = 0 \]

The highest derivatives in the examples of differential equations above are first, fourth, and third-order, respectively.

First Order of Differential Equations

The first example demonstrates a first-order differential equation with a degree of 1. The first order includes all linear equations that take the form of derivatives. It only has the first derivative, as shown by the equation $\frac{dy}{dx}$, where x and y are the two variables, and $\frac{dy}{dx} = f(x, y) = y’$.

Second-Order of Differential Equations

The second-order differential equation is the equation that contains the second-order derivative. Second-order derivates are represented by this equation $\frac{d}{dx}(\frac{dy}{dx}) = \frac{d^{2}y}{dx^{2}} = f”(x) = y” $.

What Are Ordinary Differential Equations?

An ordinary differential equation or ODE is a mathematical equation with only one independent variable and one or more of its derivatives. 

As a result, the ordinary differential equation is represented as a relationship between the real dependent variable y and one independent variable x, together with some of y’s derivatives about x. 

Since the differential equation in the example below lacks partial derivatives, it is an ordinary differential equation.

\[ (\frac{d^{2}y}{dx^{2}})+(\frac{dy}{dx})=3y\cos{x} \]

There are two types of homogeneous and non-homogeneous ordinary differential equations.

What Are Homogeneous Differential Equations?

Homogenous differential equations are differential equations in which all terms have the same degree. Since P(x,y) and Q(x,y) are homogeneous functions of the same degree, they can be generally expressed as P(x,y)dx + Q(x,y)dy = 0.

Here are some examples of homogeneous equations:

\[ y + x(\frac{dy}{dx}) = \text{0 is a homogeneous differential equation of degree 1} \]

\[ x^{4} + y^{4}(\frac{dy}{dx}) = \text{0 is a homogeneous differential equation of degree 4} \]

What Are Non-homogeneous Differential Equations?

A non-homogenous differential equation is an equation in which each term’s degree is different from the others. The equation $xy(\frac{dy}{dx}) + y^{2} + 2x = 0$ is an example of non-homogenous differential equation.

The linear differential equation is a kind of non-homogenous differential equation and is related to the linear equation.

What Are Partial Differential Equations?

A partial differential equation, or PDE, is an equation that only uses the partial derivatives of one or more functions of two or more independent variables. The following equations are examples of partial differential equations:

\[ \frac{\delta{u} }{dx} + \frac{\delta}{dy} = 0 \]

\[ \frac{\delta ^{2}u}{\delta x^{2}} + \frac{\delta ^{2}u}{\delta x^{2}} = 0 \]

Applications of Differential Equations

Ordinary differential equations are used in everyday life to compute the flow of electricity, the motion of an object back and forth like a pendulum, and to illustrate the principles of thermodynamics.

In medical terminology, they are also used to monitor disease progression graphically. Mathematical models involving population increase or radioactive decay can be described using differential equations.
