INTEGRAL ACCOUNT AND AGROECONOMIC APPLICATION OF AN INTRODUCTORY INTEGRAL

Agroeconomic events follow the formation of relationships in the society regarding transactions that occur in market systems. Integration as a mathematical operation has wide application in solving certain agroeconomic changes. The dependence of application of integration in certain agroeconomic functions takes the dominant position in solving real problems. In this connection, we will show the application of an unspecified integral in some agroeconomic events. What will we try to contribute to the application of this kind of quantitative analysis on agroeconomic factors. © 2019 EA. All rights reserved.


Introduction
Agroeconomic policy is an important segment of the overall macroeconomic policy of every society. The investigation of the phenomenon from this segment requires the application of the equimetric and quantitative models. Due to the evident domination of the marginalist economic direction, such research is gaining in importance.
The subject of this paper is to demonstrate the possibility of applying an integral account in the research of agroeconomic phenomena and processes.
Integration is an inverse operation from differentiation. Integration sign ∫ is an elongated letter S . This symbol is not arbitrarily selected as, for instance, a symbol http://ea.bg.ac.rs to summation, such as differentiation analogous to subtraction. In fact, it has been shown beforehand that it is a differential dy approximately equal to the difference 2 1 y y y ∆ = − .
If two inverse operations are executed successively over a certain size, for example, over a variable, then their operation is canceled and the size remains unchanged, i.e.
The reason that along with the appearance of one more arbitrary constant, it is easy to understand. Actually, Otherwise, this constant is indeterminate and according to it, the integral is called an indefinite integral. This inverse operation from differentiation can also be understood in the following way.
Under the sign ∫ is the difference, i.e. product derivative of function and differential of independent variables. In our previous assumption, the copy is equal 1. Therefore, the integration here meant determining a function whose output is equal to the unit. And what function does it have as a copy of 1? This, obviously, is not just a function y x = but also all linear functions of the form y x C = + . Integration is, therefore, reduced to the search for a function whose derivative is known. In other words, integration is the search for a primitive function, primitive in terms of the original.
Integration, however, is not that simple at all. In order to solve the integrals of more complex functions, it is not enough to know just the rules of differentiation.
By systematizing knowledge in the field of the integral account, significant starting points for each research can be obtained.

Literature review
The application of integral analysis in agroeconomic processes establishes a systematically marginalistic approach to the quantitative study of the process of this scientific whole (Daze, 2008).
By studying the possibility of integral modeling of the optimal development of large systems. (Markova et al., 2019) as the subject of the integral application takes the age structure of equipment according to certain types. In the case of such an integral application, it is possible to investigate and set the boundaries of integration in the agro-industry complex in order to find a replacement solution for the numerical way by optimizing the cost of replacement. conclusion that the technical The dimension has a major impact on the results and economic development.
A competitive environment imposes a need for a constant analysis of inflows and outflows of money. Due to the need to retain existing investors, a new attraction is imposed by the need for the application of analytical methods (Knežević et al., 2016). The agroindustrial complex fulfills all the necessary conditions to be the subject of analysis, contrary to the turbulent modern business. Investors monitor the inflows and outflows of money due to which they make their business decisions.
The agro industry encompasses all activities starting from harvests, transformation, storing and preparation of agricultural raw materials for production or final consumption (Wohlmuth, Kormawa, 2012). The main focus is on production and food processing, but it should not be wrongly identified with the food industry, which is processing agricultural raw materials into food and beverages (FAO et al., 2008).
In order for the development of the agro industry to be efficient, there are some necessary structural changes in agriculture and the food industry which are required. Although they are time consuming and financially demanding, the practice shows that they are manageable, but with an inadequate support of agrarian and industrial policies. (Savić et al., 2016) Taking into consideration that this paper is concerned with proving connection and interaction between integral account and introductory integral, it can be stated that the main subject of a correlation analysis is to examine the mutual strength of the relationship and the dependence between the variables. According to Durkalić and Ćurčič (2019), the examination of the direction and strength of the interaction is carried out on the basis of a correlation analysis.

Materials and methods
From the rule for the sum of differentials [ ] i the fact that the differentiation and integration of mutually inverse operations is followed ie. the integral of the sum equals the sum of the integral of the collection (Babić et al., 1996). In the same way, the rule according to which the integral of the difference is equal to the difference of the integral is performed.
If we read the following rule: [ ] , ie. the integral of a product of a constant and some function is equal to the product of the constant and the integral of this function. (Drenovak, 1999) http://ea.bg.ac.rs Now, any whole rational function can be integrated. (Ivović, 1999). For instance 4 3 If the operator is applied ∫ on both sides of the formula: is obtained, (and by applying the rule for integral sums) This is the formula for partial integration.
When to determine 2 x x e dx ∫ with partial integration, (Martić, 1976) then applying the rule is obtained If necessary to determine ln x dx ∫ using partial integration, then applying the integration rule is obtained The result obtained is checked through From the rule for differentiating the complex function

Results and Discussion
Let's take some surface of the land or machines 1  Suppose an annuity does not arrive at a discontinuous, leapfrog at the end of each year, but runs continuously throughout the year. Let her get the way every year after If rent R t ⋅ ∆ comes after t years, starting today (when 0 t = ), ie. in the interval , t t t + ∆ , then its present value, with continuous interest, is approximately . What is the current annuity value over the entire interval of Obviously, it is roughly equal to the sum: shows that it is supposed to be summed over time intervals t ∆ from 0 t = to t x = .
If 0 t ∆ → , sum converges the integral Obviously, A is a simple time function x and interest rate p . It's easy to see that A depends on the x . It's evident that it is A the bigger it is x higher, i.e., that the present value of an annuity increases when a wider time interval (Duran et al., 2018). What's more, from the above relationship it follows that 100 lim This result is interesting because it shows that the present value of annuity in the continuous and discontinuous case is the same. Therefore, the current or present value (Mitrović et al., 2015) The eternal annuity does not depend on how this rent is made, nor how interest is calculated (continuously or discontinuously).
http://ea.bg.ac.rs It follows that, in a continuous, as well as in a discounted case, the present value of annuities decreases when the interest rate rises.

Conclusions
In addition to these methods, there are a number of procedures for integrating certain types of integrals. It is, of course, more difficult to integrate than to differentiate. So, after all, with many other inverse operations. It is harder, for example, to reduce or log in than to scale. As the second root of the negative real number is not a real number, so the integral of some simple functions does not have a solution in the domain of elementary functions.
The primary aim of the agroeconomic implementation of an introductory integral lays in solving certain agroeconomic changes such as: increasing the productivity and economic strength of households, the quality of life for the agricultural and rural population and sustainable rural development. Implementing these measures requires a significant increase of budget funding and a greater exploitation of competent both European and worldwide agricultural and rural development help funds. If the methodological basis of the quantitative analysis is properly applied in the process of making and implementing the decisions, it must be followed by strengthening of institutions, infrastructural development, increasing the size of households, mechanization and equipment modernization and training of agricultural workers.
The agrarian policy should be harmonized with the industrial policy, thus impacting a more efficient development of the food industry and exporting. The application of integration in certain agroeconomic functions could find its implementation in modernization and better capacity exploitation, strengthening the ties between raw materials manufacturers and processors, and production diversification significantly increase the comparative advantages of agriculture, food self-reliability and the overall supply of services and goods.
The scientific contribution of this paper lies in a essential explanation of the integral account and an introductory integral implementation in agriculture and food industry development, as well as to mark the potentials and perspectives of its application toward more individual areas, in order to put in use the comparative advantages of agriculture.
It has practical application and can be used in the decision-making process, respecting agrarian and industrial policies. If the method of applying an integral account is correctly set, it allows the management to make timely and optimal business decisions in order to fulfill its objectives, in a longer time span.
