With the name of Almighty, dears we’re to discuss the calculus application in the field of our practical life.

First me have to say that “Calculus” is that branch which deals with the integral calculus e.g. calculation area under the curve and the deferential calculus that deals with the motion calculation, and that all are the part of our practical life. Calculus is deeply integrated with the physical science and such as physics and Bio science, so now we can say that it is more important in every aspects of life some of them we’ll here discuss.

It is found in computer science, statistics, and engineering; in economics, business, and medicine. Modern developments such as architecture, aviation, and other technologies all make use of what calculus can offer. Graph visualization are also based on that, we can easily graph the function with the help of it. Finding average of function one example is the path of an airplane. Using calculus you can calculate its average cruising altitude, velocity and acceleration.

So at the end that branch cover a lot of area of our practical life to overcome them we’d have good knowledge of it.

Another:

"Why do we study calculus,write its at least three applications"

Graded Moderate Discussion will be open on Calculus is Latin for stone, and the ancient Romans used stones for counting and arithmetic. In its most basic sense, calculus is just that a form of counting. After advanced algebra and geometry, it is the next step in higher mathematics, and is used for solving complex problems that regular mathematics cannot complete.

Calculus is the mathematics of change, of calculating problems that are continually evolving. This is possible by breaking such problems into infinitesimal steps, solving each of those steps, and adding all the results. Rather than doing each step individually, calculus allows these computations to be done simultaneously.

Calculus is useful for solving non-linear equations. For example, say you were looking for the area inside a flat rectangle.

Calculus is deeply integrated in every branch of the physical sciences, such as physics and biology. It is found in computer science, statistics, and engineering; in economics, business, and medicine. Modern developments such as architecture, aviation, and other technologies all make use of what calculus can offer. This page is designed to out line some of the applications of calculus and give you some idea of why calculus is so important and useful.

Calculus can give us a generalized method of finding the slope of a curve. The slope of a line is fairly elementary, using some basic algebra it can be found. Although we do have standard methods to calculate the area of some shapes, calculus allows us to do much more. A function can represent many things. One example is the path of an airplane. Using calculus you can calculate its average cruising altitude, velocity and acceleration.

Windows Foundation Classes for Java (WFC) provides a framework of Java packages that support components targeted for the Microsoft Windows operating system and the Dynamic HTML object model. WFC is tightly integrated with the Microsoft Visual J++™ development environment and provides a full set of Windows controls written in Java. Building a Java application for Windows is made much easier by this tight integration and the support of features such as IntelliSense, the Forms Designer, the Application Wizard, and the Object Browser. While these Visual J++ features put you well on your way to creating applications, you'll probably want to understand the structure and logic behind the packages and classes that make up WFC.

The purpose of this section is to provide a conceptual framework for the WFC packages and classes and to explain some of the fundamental WFC models. Many of the packages exist as infrastructure for the component model and can be ignored by developers focusing on using the WFC controls. Other packages are most easily accessed from the Visual J++ Forms Designer. When you start exploring the WFC library, you'll want to know which packages and classes are important for your particular application.

First thing about Windows - it is a multi-tasking environment. That means that it can actually run more than one program at one time, giving you higher efficiency. You'll need to process code for each program simultaneously, which is no easy feat. So, the makers of Windows created a system where each program was like a procedure - code was run only when the system requested for it. This meant that they needed to create a whole new system for Windows, containing the API (Application Program Interface). Code was in the form of 'events'. Only when an event occurs will code be run. Now you know why Delphi makes you type code that way!

* WFC Packages provides a high-level overview of the main packages that make up WFC.

* Working with WFC Visual Components describes the controls, forms, and graphical objects in WFC, which include the following subtopics:

o Windows Visual Components

o Dynamic HTML Visual Components

* Handling Events in WFC describes the use of delegates for handling events.

* Localizing Your Application describes the Visual J++ and WFC support and methodology for localizing your project in various languages.

* Using WFC Application Services describes some of the core application features and includes the following subtopics:

o Starting and Quitting an Application

o Handling Application Events

o Accessing System Information

o Performing Clipboard and Drag-and-Drop Operations

* Using Java Threads with WFC describes the threading model for WFC and includes the following subtopics:

o Mixing Java and Win32 Threading Models

o Creating and Exiting a Thread

o Using Thread Storage

o Working with Thread Exceptions

Construct a real world business problem and then apply simple linear regression analysis.

Question:-

Suppose that 4 randomly chosen plots were treated with various level of fertilizer in the following yield of corn:-

Fertilizer(kg/Acre) X 100 200 400 500

Production(Bushels/Acre) Y 70 70 80 100

Estimate the Linear Regression of production Y on fertilizer X.

Solution:-

X Y XY X2

100 70 7000 10000

200 70 14000 40000

400 80 32000 160000

500 100 5000 250000

å = 1200 å = 320 å =103000 å = 460000

Byx = nåXY – åXåY / nåX2 - (åX) 2

Byx = 4(103000)-((1200)(320)) / 4(460000)-(1200) 2

Byx = 0.07

ayx = y - Byx X

= ((åY/n) – ((0.07) (åX/n))

=(320/4) – (0.07)(1200/4)

= 59

y = 59 + 0.07 X is required regression equation.

Question/Description

"Briefly describe the situation where Coding of the responses can be done before the data collection and when coding is done after the data collection? "

Solution:

Briefly describe the situation where Coding of the responses can be done before the data collection and when coding is done after the data collection?

Coding before the collection of data:

Whenever is possible the best way of processing is to begin before the actual survey is carried out. Pre-coding is a procedure that applies to only close ended questions where answers are few in numbers and predictable. This can be done when questions are highly structured and only can have a few answers. It involves two operations, (1) attaching a numerical value to each response, (2) designing a location for every item in the questionnaire.

Coding after the collection of data:

When questions are open ended and answers are not predictable the coding of data is done after the data is actually collected. Categories in which responses are to be coded must be established after examining that what respondent actually had to say?

In many cases, such as when researchers are using open-ended questions, a framework for classifying responses to questions cannot be established before data collection. This situation requires some careful thought concerning the determination of categories after editing process has been completed. This is called post-coding or simply coding.
