## 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.
