Integration

Integral calculus, sometimes called the calculus of integration, has many applications in the real world – most notably in business and finance, where it’s used to find the exact value of specific measures such as the area under a curve. It’s also used in science to figure out things like the volume of liquid contained in a closed container or the amount of air flowing through an orifice over time. It might seem complicated at first, but integral calculus isn’t hard to understand if you know where to start and have some practice with the concepts involved.

Integral calculus has many uses, from determining the distance between two points on the map to finding the area inside of circles and cones. If you want to know more about it, read this article about integral calculus, its uses, and how it’s calculated.

Summation Notation

Another way to remember integration is through summation notation. The Summation Notation, just like integration and multiplication has a similar derivative and integral counterpart, respectively. In summation notation we say Sigma rather than Sum, denoting that we’re talking about a sum of terms. Consider this example: We know (or at least should know) that.

 This can be restated in summation notation as. We could represent a summation without explicitly writing out all terms by using set theory notation and setting up our indexing such that: where Σ represents how many times will take place. In other words, if, then that means there are three parts to our expression since it will take place three times in total.

Derivative Calculus

Calculus describes the change and integral calculus has a lot to do with integration. Because we’re talking about change, here are some definitions: A derivative is a measure of how fast something changes, whereas an integral is a way to add up all of those changes.

 In other words, differentiation describes the rate of change (of which there are two kinds) and integration describes accumulation. Derivative Calculus links these concepts together.

Applications of Differentiation

Differentiation can be used to find slope, and therefore, finding areas under a curve is just differentiation and integration. Integral calculus is what involves taking an integral of a function, instead of a derivative. To have a better idea of how the integration works, you might want to read about it here.

Integration has applications in many fields, including physics and mechanics; electrical engineering; economics; business analytics; finance and accounting; risk analysis. For example, if you’re trying to run a store that sells all sorts of electronics – integrating would help calculate how much total revenue you’d makeover time with certain fluctuations in income. This might seem like common sense – but essentially every field will use integral calculus in some way or another.

Why do we need integration?

We need integration because integration is a way to calculate areas under curves and derivatives are a mathematical way to measure slope and rate of change. In other words, we need integral calculus because it allows us to find areas under curves.

 Those graphs that you always use on tests aren’t just pretty pictures; they help us find out how much stuff we have. If you didn’t know calculus, then your ability to make money would be severely hindered.

How can integration be used in real life?

Integration can be used in real life to give a detailed look at how something is changing. Integration, or differentiating integral calculus, allows you to work out a large number of simple formulas for finding integrals. 

The two most common applications for integration are using definite and indefinite integrals for finding the area under a curve and integrating specific functions to find new forms of those functions. One example is taking an inverse function such as sin(x) and integrating it to find cos(x).

Conclusion

Integral calculus is an interesting branch of mathematics that is used to calculate the area beneath curves or to determine volumes of irregularly shaped objects. In this article, we’ll briefly go over the basic concepts and formulas behind integral calculus so you can start using it in your research and equations!
