What is a Differential Equation?

A differential equation is a mathematical equation that connects a function with its derivatives. These equations illustrate how a quantity changes over time or space, and they are commonly used in physics, engineering, biology, economics, and various other fields. Differential equations can be categorised as:

• Ordinary Differential Equations (ODEs): Involving derivatives with respect to a single variable.
• Partial Differential Equations (PDEs): Involving derivatives with respect to multiple variables.

For example: - ( y'(x) = x^2 ): An ODE where the derivative of ( y ) depends on ( x ). - ( \frac{\partial^2 u}{\partial x^2} + \frac{\partial^2 u}{\partial y^2} = 0 ): A PDE often used in physics.

Purpose of the Calculator
