What is Differential Equations?
“Differential Equation is a mathematical equation that relates one or more functions to its derivatives.”
General Form
\( F\left(x, y, \frac{dy}{dx}, \frac{d^2y}{dx^2}, \dots, \frac{d^n y}{dx^n} \right) = 0 \)
Explanation:
A differential equation describes the relationship between a quantity and its rate of change. Within this equation, function represents physical quantities while their derivatives show how those quantities change over time.
How To Solve Differential Equations?
- Rearrange to isolate the terms of each variable on different sides
- Perform integration on both sides, adding a constant of integration
- Manipulate the equation to isolate the dependent variables
- Substitute the given value to find the value of the constant of integration
Example:
Solve the differential equation: dy / dx = 3y
Solution:
Identify Type: This is a first-order linear differential equation.
Separate Variables: 1 / y dy = 3 dx
Integrate both sides: ∫1 / y dy = ∫ 3 dx
ln |y| =3x + C
Solve for y: y =e3x + C = Ce3x , Where C = eC (simplified constant).
Apply Initial Condition: if y (0) = 2
2 = Ce0 ⟹ C = 2
Final Solution = y = 2e3x

What are Types of Differential Equation?
Ordinary Differential Equations (ODEs)
It contains one or more derivatives of a function with respect to a single independent variable.
dy / dx + y = ex
Where y is the dependent variable, x is the independent variable.
Partial Differential Equations (PDEs)
A partial differential equation (PDE) involves partial derivatives of a function with respect to multiple independent variables.
∂u / ∂t = D ∂2u / ∂x2
Linear Differential Equations
The equation where the dependent variable and its derivatives appear only to the first power and are not multiplied together.
an(x) * (dn y) / (dxn) + an-1(x) * (d(n-1) y) / (dx(n-1)) + ... + a1(x) * (dy/dx) + a0(x) * y = f(x)
Where:
an(x) , an-1(x) and a0(x) are functions of x and f(x) is given function.
Nonlinear Differential Equations
The equation where the dependent variable or its derivatives appear with powers greater than one or are multiplied together.
(dy/dx)2 + y2 = x
Homogeneous Differential Equations
The equation where all terms involve the dependent variable or its derivatives.
d2y / dx2 + 5 dy/dx + 6y = 0
(Since the right-hand side is 0, this equation is homogeneous.)
Non-Homogeneous Differential Equations
A non-homogeneous differential equation has a nonzero function on the right-hand side.
d2y / dx2 + 5 dy/dx + 6y = ex
(The right-hand side is ex, making it non-homogeneous.)
