## Integral and Definite Integrals: Introduction

## FAQs on Difference Between Integral and Definite Integrals for JEE Main 2024

1. What is integral?

An integral is a mathematical notion that explains how concepts like displacement, area, and volume can be produced from infinitesimal data. Integration is the action of finding integrals. Calculus' fundamental and crucial operation of integration, like differentiation, can be used to resolve problems in mathematics and physics involving the area of an arbitrary form, the length of a curve, and the volume of a solid.

The following integrals are definite integrals, which are defined as the signed area of the plane region encircled by the graph of a given function between two points on the real line. Positive regions are those that are above the horizontal axis of the plane, and negative regions are those that are below. Integrals are functions whose derivative is the stated function, or antiderivatives. They are referred to as indefinite integrals in this instance.

2. What is definite integrals?

Finding the area of the curve is done using the definite integral, which is represented as ∫baf(x).dx. , where a and b are the lower and upper bounds, respectively, of the function f(x), defined with reference to the x-axis. The antiderivative of the function f(x) is the definite integrals, and the upper and lower limits are used to determine the value of F(b) - F(a).

3. Write the practical use of definite integrals.

The area of curves like a circle, ellipses, and parabolas can be calculated using the definite integrals. In essence, integration methods are used to calculate the areas of asymmetrical shapes. Applying limits allows you to compute the area of a tiny space in definite integrals, which you can then manipulate to determine the area of the total space. Calculating a circle's area involves taking its integration with respect to the x-axis in the first quadrant, setting constraints from the origin to the radius, and multiplying that result by 4.

4. Differentiate between integral and definite integrals.

An indefinite integral has no integration bounds. When the lower and upper bounds are constants, a definite integral denotes a number. An extended family of functions, whose derivatives are f, is represented by the indefinite integral. Any two family functions will always differ from one another.

5. Are all definite integrals positive?

It's possible for an integral to be negative. The area between the x-axis and the curve under study over a specific time period is calculated using integrals. If the entire period is above the x-axis but below the curve, the outcome is positive.
