Differential Equations

Introduction

Differential equations are equations that involve derivatives, or the rate of change of a function. They are an important part of mathematics, and are used to solve many problems in physics, engineering, economics, and other fields.

Differential Equations and Derivatives

Before we dive into differential equations, let's review derivatives. A derivative is the rate of change of a function. It is a measure of how quickly a function is changing.

The derivative of a function can be found by taking the derivative of each term of the function. For example, the derivative of the function f(x) = 3x2 + 5x + 2 is f'(x) = 6x + 5.

Differential Equations

Now that we know what derivatives are, let's look at differential equations. A differential equation is an equation that involves derivatives. It is an equation that describes how a function changes over time.

Differential equations can be used to model real-world problems. For example, the equation for a falling object is a differential equation. It describes how the object's velocity changes over time.

Solving Differential Equations

Differential equations can be solved using a variety of methods. The most common method is to use integration. Integration is a process of finding the area under a curve.

Integration can be used to solve differential equations. To solve a differential equation using integration, you must first find the antiderivative of each term. Then, you must use integration to find the area under the curve.

Practice Problems

  1. Find the derivative of the function f(x) = 4x3 + 5x2 - 2x.

Answer: f'(x) = 12x2 + 10x - 2

  1. Solve the differential equation y' = 4y + 3.

Answer: y = e4x - 3/4e4x + c, where c is a constant.
