One of the most important branches of mathematics includes calculus. Calculus is a manner of calculation of problems in a systematic way which usually deals with finding properties or values of functions by integrals and derivatives.

Definite vs Indefinite Integrals
The difference between Definite and Indefinite Integral is that a definite integral is defined as the integral which has upper and lower limits and has a constant value as the solution, on the other hand, an indefinite integral is defined as the internal which do not have limits applied to it and it gives a general solution for a problem.
A definite integral of a function of an unknown variable is the representation of a number which has upper and lower limits. An indefinite integral is the representation of a family of functions without limits.
|Parameter of Comparison||Definite Integrals||Indefinite Integrals|
|What it means||A definite integral is the one that has lower and upper limits and on solving gives a constant result.||An indefinite integral is the integral in which no limits are applied and has a mandatory arbitrary constant added to the integral.|
|What it represents||The definite integral represents the number when its upper and lower limits are constant.||An indefinite integral is a general representation of a family of various functions with derivatives f.|
|Limits applied||The upper and the lower limits applied in a definite integral are always constant.||In indefinite integral, there are no limits since it is a general representation.|
|Solution obtained||The values or solutions obtained from definite integrals are constant, however, they can either be positive or negative.||The solution of an indefinite integral is a general solution and it has a constant value added to it which is generally represented by C.|
|Used for||A definite integral is widely used in physics and engineering. Some of the areas of use of a definite integral include calculation of values of force, mass, work, areas between curves, volumes, act length of curves, surface areas, moments and center of mass, exponential growth and decay, etc.||Indefinite integrals are of use in fields like business, sciences including engineering, economics, etc. It is used in areas where a general solution is required for a problem.|
What is a Definite Integral?
A definite integral is defined as the representation of a number which gives a constant result. A definite integral always has an upper limit and a lower limit.
The solution can either be positive or negative. The solution obtained from a definite integral always lies in a specific area.
Some areas where definite integrals are used are a calculation of work, force, mass, areas, surface areas, the area between curves, length of arcs, moments, center of mass, exponential growth and decay, etc.
What is Indefinite Integral?
An indefinite integral is defined as the integral without limits. The indefinite integral is the representation of a family of various functions having derivative f.
The solution obtained on solving the unknown function of an indefinite integral is a generalized solution and therefore it also has variables in it. The area of the solution of an indefinite integral is not specified.
Indefinite integrals are used at places where a general solution to the problem is required. Indefinite integrals are used in business, sciences, engineering, economics, etc.
Main Differences Between Definite and Indefinite Integral
- A definite integral can be defined as the integral which has limits, on the other hand, an indefinite integral can be defined as the integral without limits.
- A definite integral is the representation of the number when it has upper and lower limits constant whereas an indefinite integral is the representation of the general solution for a family of functions having derivative f.
