INTEGRATION:
Calculus:
The branch of mathematics that deals with the rate of changes of moving objects is called calculus. Hence, in calculus, various different kinds of models are deduced for the smooth modeling of systems where there is a change. Sir Isaac Newton and Gottfried Wilhelm are said to be the founding members who developed the concepts of calculus in the 17th century. The principles of calculus are based on the studies of limits, differential calculus (derivations), integral calculus (integration), and fundamental theorems.
DEFINITION
Integration is an important operation of calculus. It is a process of assimilating different occurrences (variables).
Explanation:
In calculus and mathematics, integrals are often used as calculating the area of a two-dimensional or three-dimensional body that has curved shapes. Moreover, the branch of calculus that deals with such activities are called integral calculus, and the process is called integration. It is worth mentioning here that integration is anti-differentiation that means if you are going to take the first derivative and then integrate of the same function, the original function will appear again. Integration is usually denoted by ∫ that sometimes include the upper and lower limit as well. It is worth mentioning here that, differentiation often is more concerned about the curve, while integration deals with areas under the curve.
EXAMPLE:
If you are traveling from your house to your school in your car, we have two variables; speed (velocity) of the car and time taken to reach the destination. So its speed may vary, for some time you have to slow down your vehicle, sometimes you have speeded it up or there might come a time when you have to put a halt to it. If you were asked to tell at what speed (velocity) you have arrived at your school, you might not have an exact answer because the velocity kept changing with regard to time.
FORMULA:
Integral of a function with respect to variable ‘x’ can be written as
∫f(x)dx
Where
f (x) = function of x
x = variable
∫ = integral symbol
TYPES OF INTEGRATION:
There are two types of integration
- Definite integration: It has start values and end values e.g. ‘x’ and ‘y’. x and y can be also called boundaries, limits of a function. In the end, we get a definite answer.
- Indefinite integration: It has no upper or lower limits, and by the end of the problem, we still get a variable in the answer.
Another type of integration:
- There is another type known as shell method integration. it is used When integrating along an axis perpendicular to the axis of revolution.
- Another type of integration is washer method integration. It is used to calculate the volume of a solid of revolution of a solid-state material.You can calculate these shell method and washer method integration-related questions by using the shell method calculator and washer method calculator easily.
DERIVATION:
DEFINITION:
Inverse Integration is Derivation. Derivation of any function (variable) is the ability to change with respect to its argument (surroundings). The derivation is a word taken from derived, which means ‘to obtain’. In Mathematics, it means ‘to acquire’ something from another sequence by performing a series of operations.
Explanation:
The function of a variable that measures the change in a given parameter with respect to the change in the argument is called a derivative. The process by which the derivative of a given function is calculated is called derivation. Moreover, the branch of calculus that deals with the definition, problems, applications, and properties of derivatives are called differential calculus. Hence, the rate of change of numerous functions with respect to various variables is studied in differentiation. The notation of derivative is often given as dy/dx which is read as derivative of y with respect to a derivative of x and sometimes as dy by dx and dy over dx. The given table below shows the derivative of some common functions.
FORMULA:
the derivative of ‘y’ w.r.t ‘x’ will be written as
dy/dx
EXAMPLE:
we have and equation
f’(x )= 3+x
then
derivation of f’(x) will be
f’(x)=d/d(x) [3+x]
f’(x)=d/d(x) [3] + d/d(x) [x]
f’(x)= 0+1 as we know derivative of constant is ‘0’
and derivative of x is ‘1’
therefore
f’(x)= 1
SIGNIFICANCE OF DERIVATIVES & INTEGRATIONS
- Integration helps the students to understand the problem deeply and minutely. By simply dividing the equation into smaller fragments, students can observe the minor details and by unraveling it, they can get an accurate answer.
- Regardless of any particular domain, it is essential to show pupils that how different equations are formed so that they can understand the logic behind it and start reasoning with it. When students understand the reasons behind the problems, problem-solving skills are ultimately developed.
APPLICATIONS OF INTEGRATION AND DERIVATION
Calculus, integration, and differentiation have many practical applications in our daily life. Motion, electricity, heat, light, electromagnetism, laws of inertia and algebra all follow the rules of calculus. Moreover, it is very well written that from calculating the decay of radioactive materials to predict the death and birth rates, scientists use basic and advanced laws of both integration and differentiation. Similarly, fluid motions, reactor designs, bridge engineering, process designs, and simulations can only be studied if one has very stiff concepts of calculus. The importance of calculus can be predicted via the fact that in the curriculums of all engineering and non-engineering courses special attention and dedication is given to design the calculus, integration, and derivation courses so that the students can grasp the knowledge and concepts of these subjects quite easily and can solve their problems once they get industrial jobs. Even though calculus finds many applications in our daily life, some of the most important applications are explained below:
- Calculus is very important in calculating the supply, demand, and relationship correctly. Moreover, the economists use the basic principles of integration and derivation to predict the maximum profit that can be attained by a business by studying the potential curves, and hence the future analysis of the specified products can be easily made.
- Biologists use calculus to predict the growth of bacteria in its culture by varying the process parameters like temperature, pressure, light, moisture content and the supply and nature of nutrition.
- The nature and spread of Covid-19 were very closely monitored by doctors and engineers by making the curves via realistic data. Hence, accurate curves and models were prepared that proposed how fast the virus is spreading and which are the badly affected areas by this disease. This was made possible by utilizing the concepts of calculus.
- In engineering as well, calculus finds many practical applications. Chemical engineers design reactors by using the formula of integration and differential. The nature of fluid flowing through the pipes, the pressure drop along the wall of the pipes, the amount of liquid passing through the pipe are all estimated by using calculus, integration, and differentiation. Similarly, the length of power cables needed to connect two distant stations is calculated by electrical engineers using integrations. Moreover, the architect and civil engineers calculate the amount of material required to construct the carvery surfaces by using laws and formulas of integration and differentiation.
- Statisticians use calculus to evaluate the data collected through various surveys that help them to stabilize their business. With the help of various analyses on the surveys via calculus they can estimate how much their business is flourishing and where they need to improve.
- In chemistry, derivation and integration find many applications in calculating the speed of chemical reactions. Moreover, the activation energy, order of reaction, and extent of radioactive decay can be calculated via formulae of calculus.
- The space engineers also consider the calculus concepts when they are going to launch a space satellite as the study of the movement of earth and other planets is very important.
- The concepts and formulae of integrations and differentiation are very important in research, development, and innovation. By considering the change in various functions with respect to variables, the companies can predict the future of their products. Hence, not only the quality and market demand of the product can be predicted, the owners can also analyze how much they are going to earn in the near future.
- Lastly, calculus also finds its practical applications in physics, mathematics, geography, sociology, algebra, geometry, graphics, and image processing. Hence, to be an efficient person it is mandatory that one should possess sound knowledge and skills in calculus so that he might solve the problems related to integration, differentiation and fundamental theorems effectively.
