Technically speaking, applications of definite integrals are often used to measure or calculate areas between 2 curves, volumes, length of curves, and of course, many other applications from every day life like, for instance, the work done by a force, the pressure exerted by a liquid on an object, and basic statistical concepts. We've put up the following quiz just for you, complete it and good luck!

### What is a summed-area table?

• A.

It's a data structure and algorithm for quickly and efficiently generating the sum of values.

• B.

It's a data structure for quickly and efficiently generating the sum of values.

• C.

It's a data structure and algorithm for quickly and efficiently generating values.

• D.

It's a data structure and algorithm for quickly and efficiently generating real values.

A. It's a data structure and algorithm for quickly and efficiently generating the sum of values.
Explanation
A summed-area table is a data structure and algorithm that allows for the fast and efficient calculation of the sum of values. It is commonly used in computer graphics and image processing to quickly generate the sum of pixel values in rectangular regions. By precomputing and storing cumulative sums, the summed-area table enables rapid retrieval of the sum of values for any given rectangular region without the need for iterating through all the individual values. This makes it a valuable tool for various applications that require fast and efficient computation of summed values.

### What is the formula for a definite integral?

• A.

F(x). d(x)= a+b

• B.

B-a= f(x)

• C.

b ∫     f(x) dx   a

• D.

A/b= f(x)

C.   b ∫     f(x) dx   a
Explanation
The correct answer is the formula for a definite integral, which is ∫ f(x) dx from a to b. The integral sign represents the process of finding the area under the curve of the function f(x) between the limits of a and b.

### How can you define a definite integral?

• A.

It's the area of the region in the xy-plane bounded by the grapH of f, the x-axis, and the line x=a.

• B.

It's the area of the region in the xy-plane bounded by the grapH of f, the x-axis, and the line x=a and x=b.

• C.

It's the area of the region in the xy-plane bounded by the grapH of f, the x-axis, and the line x=c

• D.

It's the area of the region by the grapH of f, the x-axis, and the line x=a and x=b.

B. It's the area of the region in the xy-plane bounded by the grapH of f, the x-axis, and the line x=a and x=b.
Explanation
A definite integral is used to calculate the area of the region in the xy-plane that is bounded by the graph of f, the x-axis, and the lines x=a and x=b. This means that the integral calculates the area between the curve and the x-axis within the specified limits of a and b.

### What happens when the interval is infinite?

• A.

Then the indefinite integral is called an improper integral.

• B.

Then the definite integral is called an improper integral.

• C.

Then the function becomes insolvable

• D.

Then the solution is negative.

B. Then the definite integral is called an improper integral.
Explanation
When the interval is infinite, the definite integral is called an improper integral. This is because the limits of integration extend to infinity, making it impossible to evaluate the integral using the usual methods. Instead, special techniques such as limits or convergence tests are used to determine the value of the integral.

### What relates antiderivatives to definite integrals?

• A.

Space.

• B.

The theory of relativity

• C.

The invention of the light bulb

• D.

The fundamental theorem of calculus.

D. The fundamental theorem of calculus.
Explanation
The fundamental theorem of calculus relates antiderivatives to definite integrals. This theorem states that if a function is continuous on a closed interval, then the definite integral of its derivative over that interval is equal to the difference between the values of the antiderivative at the endpoints of the interval. In other words, it provides a method to evaluate definite integrals by finding antiderivatives of the integrand. This fundamental theorem is a key concept in calculus and is widely used in various applications of mathematics and science.
