Integration can be used to find areas, volumes, central points and many useful things. But it is easiest to start with finding the area under the curve of a function like this:. So you should really know about Derivatives before reading more!
The symbol for "Integral" is a stylish "S" for "Sum", the idea of summing slices :. After the Integral Symbol we put the function we want to find the integral of called the Integrand. It is the "Constant of Integration". It is there because of all the functions whose derivative is 2x :. Because the derivative of a constant is zero.
So when we reverse the operation to find the integral we only know 2xbut there could have been a constant of any value. Integrating the flow adding up all the little bits of water gives us the volume of water in the tank. Derivative: If the tank volume increases by x 2then the flow rate must be 2x. You only know the volume is increasing by x 2.
We can go in reverse using the derivative, which gives us the slope and find that the flow rate is 2x. If we are lucky enough to find the function on the result side of a derivative, then knowing that derivatives and integrals are opposites we have an answer.
But remember to add C. From the Rules of Derivatives table we see the derivative of sin x is cos x so:. But a lot of this "reversing" has already been done see Rules of Integration. On Rules of Integration there is a "Power Rule" that says:. Learn the Rules of Integration and Practice! A Definite Integral has actual values to calculate between they are put at the bottom and top of the "S" :. Hide Ads About Ads. Introduction to Integration Integration is a way of adding slices to find the whole.
That is a lot of adding up! But we don't have to add them up, as there is a "shortcut".How to install apk on samsung smart tv 7 series
Like here: Example: What is an integral of 2x? We know that the derivative of x 2 is 2x Rules of Integration Calculus Index. And as the slices approach zero in widththe answer approaches the true answer.Chapter 7 Class 12 Maths Exercise 7.

The Integral The calculation of the area under a curve as the limit of a Riemann sum of the area of 2. To nd the solutions.Integration is the inverse of differentiation. In other words, if you reverse the process of differentiation, you are just doing integration. The outcome of the integration is called integral. Therefore, the result is called indefinite integral.
The general integration gives us a constant to signify the uncertainty of the numerical value that could be added or taken away from the result. In definite integral, there is no room for the constant, as the integration is performed between a certain range of the variable. The area between a curve and the x-axis is the definite integral of the function of the curve within the given range of x.
You can change the position of the sliders to change a and b to see it. First of all, let's find the point of intersection of the curve and the line.

Its relation to differentiation. Why the inverse of differentiation process becomes integration. How a set of special questions help you master the topic.Since we know how to get the area under a curve here in the Definite Integrals sectionwe can also get the area between two curves by subtracting the bottom curve from the top curve everywhere where the top curve is higher than the bottom curve.❖ Basic Integration Problems
And sometimes we have to divide up the integral if the functions cross over each other in the integration interval. Area of Region Between Two Curves. Now that we know how to get areas under and between curves, we can use this method to get the volume of a three-dimensional solid, either with cross sections, or by rotating a curve around a given axis.
When doing these problems, think of the bottom of the solid being flat on your horizontal paper, and the 3-D part of it coming up from the paper. Cross sections might be squares, rectangles, triangles, semi-circles, trapezoids, or other shapes. Here are examples of volumes of cross sections between curves. Since we know now how to get the area of a region using integration, we can get the volume of a solid by rotating the area around a line, which results in a right cylinder, or disk.
So now we have two revolving solids and we basically subtract the area of the inner solid from the area of the outer one. Note that for this to work, the middle function must be completely inside or touching the outer function over the integration interval. Since I believe the shell method is no longer required the Calculus AP tests at least for the AB testI will not be providing examples and pictures of this method.

Area Between Curves Since we know how to get the area under a curve here in the Definite Integrals sectionwe can also get the area between two curves by subtracting the bottom curve from the top curve everywhere where the top curve is higher than the bottom curve.Any society, regardless of its size, degree of development and political system, tries to solve their the basic economic problems of deciding how to satisfy the unlimited needs of its market through limited Resources.
Below is the list of basic economic problems that must be in your mind as an entrepreneur. And for whom to produce? Every society must decide how to allocate its resources between the different productive activities and how they are going to distribute the goods and services of consumption between the individuals that compose it. Consequently, the economic system of a society is the set of relationships and institutionalized procedures with which it tries to solve the basic economic problem.
What to produce? The answer to the first question indicates in which the productive resources will be used and how much of the final product will be obtained with these means of production. This will depend on the needs of the members of society and the resources available, since the latter are limited and susceptible to alternative uses.
This fact raises other questions: Will more consumer or production goods be consumed? Will the quantity or quality in the production be the primary factor? Will the production of material goods or the provision of services increase?
Will goods be produced for the internal market or will production be directed towards the outside? How to produce?
This question refers to the organization of production, that who is going to be in charge of carrying out the productive activity, how this activity is going to be undertaken and how the productive factors that are available will be combined. All of this implies that society will ask questions such as whether intensive technologies will be used in machinery or labor, whether it will be done through private companies or public initiative, what sources of energy will be used in production or if the productive processes by Those that will be chosen will be polluting or respectful with the environment.
Derivatives of algebraic functions problems with solutions pdf
For whom to produce? Every society should design a system of distribution of goods and services, which leads to reflect on issues such as: Who will be the target of that production, a few or the vast majority of citizens? What method or system will be used to distribute the entire production? Will the distribution of income be equal or will there be very sharp differences between members of society? However, in reality, there are unlimited needs and limited resources available and manufacturing techniques.
Based on these restrictions, the Economy must choose between the goods to be produced and the technical processes capable of transforming scarce resources into production. This factor and the answer to these questions are closely linked to the production management, the economy and of course the Financial Management, because as seen previously, to produce you need to invest and to invest you need planning and resources.
Therefore, Financial Management comes to support the economy. Presenting now a classical division of economics, microeconomics and macroeconomics, it will be verified that, however great the differences between them, Financial Management is present and with a high degree of importance.
In this way it is distinguished from macroeconomicsbecause it is interested in the study of aggregates as the production, consumption and income of the population as a whole.
The bifurcation of Economic Science in these two branches, that is, macroeconomics and microeconomics, date of The criteria adopted for the distinction are, however, fragile, since the understanding of any economic phenomenon inevitably requires the interrelationship of the theories that are inserted both within the scope of the micro segment and in the macro branch of Economic Science.
Among these criteria, the first one is based on the level of abstraction-ism involved. Indeed, as author Robert Y.
Awh ponders, microeconomics, in laying down general principles, is far more abstract than macroeconomics, which is concerned with the examination of questions and measures peculiar to a given place and instant of time. Secondly, microeconomics presents a microscopic view of economic phenomena, and macroeconomics, a telescopic lens, that is, the latter has much larger amplitude, appreciating the functioning of the economy in its global.
It follows a comparative title: considering a forest, microeconomics would study the plant species that comprise it, that is, the composition of the product as a whole, while the macroeconomics would worry about the total product level the forest and its operation. A third way of distinguishing microeconomics and macroeconomics encompasses the analysis of the behavioral forms of aggregate variables and individual variables.
However, the aggregativity here explained must be understood in terms of the homogeneity or not of the set considered. For examplethe large aggregates studied by macroeconomics such as income, employment and unemployment, consumption, investment, and savings are all heterogeneous in nature. Microeconomics is devoted to the appreciation of the individual units of the economy. It should be noted, however, that both Aggregate Demand and Aggregate Supply allow us to obtain a standard element of the set, given the homogeneous character of which they are endowed.
The last and no less important criterion of distinction between microeconomics and macroeconomics rests on the price aspect.These revision exercises will help you practise the procedures involved in integrating functions and solving problems involving applications of integration.
