Differential equations are mathematical equations that involve one or more functions and their corresponding derivatives. These equations play a crucial role in various fields, including physics, engineering, and economics. If the equation includes partial derivatives, it is referred to as a partial differential equation. The order of a differential equation is determined by the highest order derivative present in the equation.

In this formula, p(t) and g(t) are continuous functions.
The function y(t) can be expressed as:
Here,
Example of a Differential Equation
Example:
= 9.1 – 0.18v, v(0) = 46 , find the solution to this differential equation.
Solution:
Using the integrating factor, the differential equation becomes:
Integrating on both sides, we get:
Given, v(0) = 46
⇒ v(0) = 46 + ce -0.18(0)
⇒ 46 = 46 + c
⇒ c = 0
Hence, v(t) = 46
