## What is the function of a definite integral?

Definite integrals represent the area under the curve of a function and above the 𝘹-axis.

**Why is application integration important?**

Application Integration allows businesses to operate more efficiently by simplifying their communications and reducing the time and effort on different activities. This means that the organization will spend less time on complex processes and benefit from using the same resources.

**What are indefinite integrals used for in real life?**

The indefinite integral gives the general function of the problem if the derivative is already known. It can evaluate the different results by substituting the values of variable t in the function. The predicted value of the house can be estimated by using indefinite integral method.

### What is definite integral explain with example?

Definition of definite integral : the difference between the values of the integral of a given function f(x) for an upper value b and a lower value a of the independent variable x.

**What is application integration and its characteristics?**

The most basic application integration definition is when multiple software applications designed for individual specific purposes are merged to work together with one another.

**What is one practical use of the indefinite integral?**

#### Why do we need indefinite integral?

An indefinite integral is a function that takes the antiderivative of another function. It is visually represented as an integral symbol, a function, and then a dx at the end. The indefinite integral is an easier way to symbolize taking the antiderivative.

**Who invented definite integrals?**

The modern notation for the definite integral, with limits above and below the integral sign, was first used by Joseph Fourier in Mémoires of the French Academy around 1819–20, reprinted in his book of 1822.

**What is the first property of definite integral?**

Properties of Definite Integrals Proofs This is the simplest property as only a is to be substituted by t, and the desired result is obtained. If f’ is the anti-derivative of f, then use the second fundamental theorem of calculus, to get I = f'(q)-f'(p) = – [f'(p) – f'(q)] = – q∫p(a)da.

## What is the difference between a definite integral and an indefinite integral?

A definite integral represents a number when the lower and upper limits are constants. The indefinite integral represents a family of functions whose derivatives are f. The difference between any two functions in the family is a constant.

**What are the different properties of definite integral?**

Properties of Definite Integrals

Properties | Description |
---|---|

Property 1 | ∫kj f(x)dx = ∫kj f(t)dt |

Property 2 | ∫kj f(x)g(x) = -∫kj f(x)g(x) , also ∫jk f(x)g(x) = 0 |

Property 3 | ∫kj f(x)dx = ∫lj f(x)dx + ∫kl f(x) |

Property 4 | ∫kj f(x)g(x) = ∫kj f(j + k – x)g(x) |
