Differential Equation
A differential equation is an equation that involves a derivative of one or more unknown functions. It is used to model various phenomena in physics, engineering, economics, and other fields.
There are several types of differential equations, including:
- Oscillatory equations
- Epidemic models
- Heat transfer equations
- Electric circuits
- Chemical reactions
- Biological systems
Differential Equation Type | Description | Example |
---|---|---|
Oscillatory equations | Equations that model periodic phenomena, such as sound waves or population growth. | y'' + y = sin(x) |
Epidemic models | dy/dx = kS - kI | |
Heat transfer equations | ?u/?t = α ?^2 u/?x^2 + β (?u/?x) |
Solving Differential Equations
Solving differential equations involves finding the values of one or more unknown functions. There are several methods for solving differential equations, including:
- Separation of variables
- Integration
- Undetermined coefficients
- Variation of parameters
The steps for solving a differential equation using separation of variables are:
- Write down the differential equation
- Rearrange the equation to isolate one unknown function on one side
- Separate the constants from the dependent variable
Numerical methods for solving differential equations include:
- Runge-Kutta method
- Euler's method
- Newton-Raphson method
- Finite difference methods
