What Is the Definition of Integral?

/ɪnˈtɛg rəl/ /ɪnˈtɛgrəl/ /ˈɪn tɪ grəl/ /ˈɪntɪgrəl/

If we look at any of the many trusted English Language Dictionaries, we will see that integral means something that is very important and more often than not, necessary. A good example of this would be stating that you are an integral part of your team — the usage of integral here implies that your team would simply not function without you. 

When used as an adjective, integral has a few slightly varying definitions, which we have listed for you to review below:

  • Composed of confident parts
  • Crucial to completeness 
  • Lacking nothing essential

Additionally, the Collins Dictionary states that integral — when used in reference to mathematics — refers to either a definite integral or indefinite integral. Below you will find a quick guide on both definite and indefinite integrals:

  • Definite Integral — A definite integral or Riemann integral, of a function f(x), is an integral in which the range of integration is specified. A Riemann integral’s value equals the area on a graph bounded by two given coordinates, the x-axis and a curve.
  • Indefinite integral — also called an antiderivative of a function f(x); refers to any function that, when differentiated, yields a given function. Furthermore, integration is the process of finding an indefinite integral. It should be noted that an indefinite integral is most commonly seen in symbolic form, which is written ∫ f(x)dx where f(x) is the given function.
