Common Mistakes to Avoid

Forgetting the Constant

When solving $\frac{dy}{dx} = y$ , the solution is $y = Ce^x$ , not just $y = e^x$ . Always include the arbitrary constant $C$ in your solution.

Wrong Integration Technique

For separable equations like $\frac{dy}{dx} = xy$ , separate variables first: $\frac{dy}{y} = x dx$ , then integrate both sides.

Incorrect Initial Conditions

When given initial conditions like $y(0) = 1$ , substitute $x = 0$ and $y = 1$ into your general solution to find the specific value of $C$ .

How to Solve Differential Equations

A differential equation is an equation that relates a function with its derivatives. Solving differential equations involves finding the function that satisfies the equation.

$F(x, y, y', y'', \ldots) = 0$

This is the general form of a differential equation where $y$ is the unknown function and $y'$ , $y''$ , etc. are its derivatives.

Solution Methods

Important Solution Techniques

$\frac{dy}{dx} = f(x)g(y) \Rightarrow \int \frac{dy}{g(y)} = \int f(x) dx$

$y' + P(x)y = Q(x) \Rightarrow y = e^{-\int P(x)dx}\left[\int Q(x)e^{\int P(x)dx}dx + C\right]$

Examples

First-Order Linear

$\frac{dy}{dx} = y$

Solution:

Separate variables: $\frac{dy}{y} = dx$
Integrate: $\ln|y| = x + C$
Solve for y: $y = Ce^x$

$y = Ce^x$

Separable Equation

$\frac{dy}{dx} = xy$

Solution:

Separate variables: $\frac{dy}{y} = x dx$
Integrate: $\ln|y| = \frac{x^2}{2} + C$
Solve for y: $y = Ce^{x^2/2}$

$y = Ce^{x^2/2}$

Second-Order Linear

$y'' + y = 0$

Solution:

Characteristic equation: $r^2 + 1 = 0$
Roots: $r = \pm i$
General solution: $y = C_1\cos(x) + C_2\sin(x)$

$y = C_1\cos(x) + C_2\sin(x)$

Frequently Asked Questions

What is a differential equation?

A differential equation is an equation that relates a function with its derivatives. It describes how a quantity changes with respect to another variable, often time or position. Differential equations are fundamental in modeling real-world phenomena in physics, engineering, biology, and economics.

What is the difference between ODE and PDE?

An ODE (Ordinary Differential Equation) involves functions of a single variable and their derivatives, like $\frac{dy}{dx} = y$ .
