Applications of Partial Differential Equations
PDEs are applied in a lot of fields like mathematics, engineering, physics, finance, etc. Some of their applications are as follows:
- The concept of heat waves and their propagation can be conveniently expressed by way of a partial differential equation, given as,
uxx = ut
- Light and sound waves and the concept surrounding their propagation can also be explained easily by way of a partial differential equation given as,
uxx – uyy = 0
- PDEs are also used in the areas of accounting and economics. For example, the Black-Scholes equation is used to construct financial models.
Partial Differential Equation
Partial Differential Equation contains an unknown function of two or more variables and its partial derivatives with respect to these variables. The order of partial differential equations is that of the highest-order derivatives. Such equations aid in the relationship of a function with several variables to their partial derivatives. They are extremely important in analyzing natural phenomena such as sound, temperature, flow properties, and waves.
They are used to express issues that include an unknown function with numerous dependent and independent variables, as well as the second derivative of this function with respect to the independent variables.
In this article, we will learn the definition of Partial Differential Equations, their representation, their order, the types of partial differential equations, how to solve PDE, and many more details.
