Continuous Integration

What is Continuous Integration?

In mathematics, Integration is a process of adding up small parts to find the whole. And when we discuss integration, we should also know what is continuous integration. Continuous integration involves assigning numeric values to some functions, which has some potential for minimal data or value for it. Typically, the continuous integral value is used to finding out displacement, area, volume, and similar dimensions in mathematics. Continuous integration refers to assigning actual numbers to particular functions, which holds a negligible data or value for it. Integration can have a lot of practical applications. For instance, when you want to determine the electricity bill, you don’t want to pay the bill by the power consumed every minute. Instead, you would want a monthly bill that accounts for all kilowatts consumed in the period. Here energy (kilowatts/hour) is the integral of power with time.


Basics of Continuous Integration

By bringing together tiny pieces of data, integrals designate a number to a function in a way that represents displacement, area, and volume. You must know that integration and differentiation are the two major operations of calculus. Also, Integral and differential calculus both rely on the fundamental theorem of calculus. 


Consider that f(x) is continuous in the interval a <= x <= b and G(x) is a function that looks like (dG)/(dx) = f(x) for all values of x in [a, b]. In such a case, when f is continuous on an interval I, you have to choose a point a in I. That way, the function f(x) gets defined as;


F(x) = ∫ax f(t) dt


Here, let c be in I and let x be indefinitely close to c, between the endpoints of I. 


So, by the property of addition, you get –


ac f(t) dt = ∫ax f(t) dt +∫xc f(t) dt,

ac f(t) dt – ∫ax f(t) dt = ∫xc f(t) dt,

f(c) – f(x) = ∫xc f(t) dt


Example to determine continuous integration: 


In continuous integration, let f(y) = in y, u(a) = a, and v(a) = a. In such case, the function cannot depend on ‘a’ all the time, it has to get substituted with u, v, and f. 


Then, you get - \[\frac{{(d) }}{(d \alpha)}\]  \[\int_{\alpha}^{a}\] In, y, dy = \[\frac{{(f \alpha) (d,a) }}{(d\alpha)}\]


Types of Integration

Generally, there are two types of integration: definite and indefinite integral. The fundamental theory of calculus has a variety of applications such as, primarily computing the wider areas and finding the average of the continuous functions. 

  • Definite Integral: It refers to an integral of a function which has limits for integration. Two values determine the limits for the interval of integration. One value denotes the upper limit while other shows the lower limit. And there is not constant of integration in this type. 

  • Indefinite Integral: It is an integral of a function which has no limits for integration. It’s a method for computing indefinite integrals, also known as anti-derivatives in calculus. However, it has an arbitrary constant. It denotes a sense of ambiguity. 

  • There is one more integration, known as numerical integration. It provides a numerical approach to evaluation and computation with computer operations, definite integral. And also for flinging solutions to differential equations. 

  • Order of integration is the subtype of integration. It refers to a certain number of times when ‘time scale’ decreases with a mere objective of getting it fixed. Those were various integration types that are in use today.
