# Definite integrals introduction

Contents
Definite integrals are a way to describe the area under a curve. Make introduction with this intriguing concept, along with its elaborate notation and various properties.

## Definite integral as area

Introducing the definite integral. It's basically a way to represent the area under a given curve with left-hand and right-hand bounds.

## Definite integral properties

Definite integrals behave is specific ways with shared properties. For example, the sum of the definite integrals of a function f from a to b and from b to c is equal to the definite integral of f from a to c. Learn about these properties and use them in order to evaluate integrals.
