LEARNING CALCULUS
Prepared by: Susan Hermiller, Melanie Martin, Eric York Welcome to the wonderful world of Calculus. In order to help you get the most out of Calculus, we have prepared the following to help you make better use of your study time and to make you aware of some of the resources available for help, if you need it. Some Initial Pointers: Calculus is likely to require that you make a substantial investment of TIME . Probably a minimum of three hours outside class for every hour you spend in class. Build this into your life. You should work on it some everyday, whether you have class or not and whether anything is due or not. One of the advantages of mathematics is that it can be done virtually anywhere, anytime. You can use time when you are in the shower or waiting in line to be thinking about problems or going over new concepts in class. One of the best ways to learn anything is to explain it to someone else. Working in groups is a good way to provide yourself with this opportunity. You can also amaze your friends with careful explanations of, say, all of the different interpretations of the concept of a derivative. Math is not a spectator sport. You will need to actively participate, roll up your sleeves and get that pencil moving. You will also need to move your brain. Expect to have to think about concepts and problems. Some of the problems you will encounter will teach you new techniques: like playing scales in a musical instrument, or running laps around a track. You might not see the point immediately, but they are strengthening you so everything will come together when it counts. Think of them as push-ups for the brain and practice them often. Some problems will require you to think hard and pull concepts together (at this point you will be glad you did your push-ups). Take some time with them, talk about them, take breaks if you are getting frustrated, ask for help if you are stuck, enjoy the process: you are learning.

Thomas' Calculus
This guide to the history of calculus is keyed to the chapters and content of the 10th edition of Thomas' Calculus . This electronic document highlights important events and people in the development and use of calculus.
Learn about the history of calculus
The history of calculus is rich and full of considerable human effort. By investigating this guide, through the sections containing a timeline, essays on the development of the major elements and topics of the subject, biographies of over 100 contributors and users of the subjects, and a set of over 100 problems (questions keyed to chapters in the book) to investigate in the history of calculus, you can learn more about the subject and how it has been used to help society.
Use with the textbook
These history modules (topic essays and biographies) can be used to supplement a reading assignment or lecture or with the problem exercises can supplement the outside class work. They are excellent sources for written or oral projects. The textbook contains icons that indicate good places where history modules can be used.

Elementary Calculus: An Approach Using Infinitesimals
On-line Edition, by H. Jerome Keisler
This is a calculus textbook at the college Freshman level based on Abraham Robinson's infinitesimals, which date from 1960. Robinson's modern infinitesimal approach puts the intuitive ideas of the founders of the calculus on a mathematically sound footing, and is easier for beginners to understand than the more common approach via limits.

Calculus In general, "a" calculus is an abstract theory developed in a purely formal way. "The" calculus, more properly called analysis (or real analysis or, in older literature, infinitesimal analysis ) is the branch of mathematics studying the rate of change of quantities (which can be interpreted as slopes of curves) and the length, area , and volume of objects. The calculus is sometimes divided into differential and integral calculus , concerned with derivatives
and integrals
respectively. While ideas related to calculus had been known for some time ( Archimedes' method of exhaustion was a form of calculus), it was not until the independent work of Newton and Leibniz that the modern elegant tools and ideas of calculus were developed. Even so, many years elapsed until the subject was put on a mathematically rigorous footing by mathematicians such as

Abstract: We present the fusion calculus as a significant step towards a canonical calculus of concurrency. It simplifies and extends the -calculus. The fusion calculus contains the polyadic -calculus as a proper subcalculus and thus inherits all its expressive power. The gain is that fusion contains actions akin to updating a shared state, and a scoping construct for bounding their effects. Therefore it is easier to represent computational models such as imperative and concurrent constraints... (Update)

There are two components to calculus. One is the measure the rate of change at any given point on a curve. This rate of change is called the derivative. The simplest example of a rate of change of a function is the slope of a line. We take this one step further to get the rate of change at a point on a line. The other part of calculus is used to measure the exact area under a curve. This is called the integral. If you wanted to find the area of a semicircle, you could use integration to get the answer.
The two parts; the derivative and the integral are inverse functions of each other. That is, they cancel each other out.
Just as (x =x,
the derivative of (integral (x)) = x and
derivative of (integral (f (x)) = f(x). The derivative is a composite function. This means it is a function acting on another funcion. In fact, the function, is the input instead of just x. The derivative, then takes a type of formula and turns it into another simiilar type of formula. So, a polynomial will always yield a polynomial derivative. A trigonomic function will always yield a trigonomic derivative. There are a few exceptions, but this is generally the case. This is also true for the integral. Back To Top Geometrically, the derivative can be perceived as the slope of the tangent line to a curve at a given point. This is roughly how steep the curve is at a given point. We can easily find the rate of change of a line just by finding the slope. But, most formulas are not as simple as a line and they're usually curved. We use the basic formula of a line to get the derivative. If you remember the slope of a line is:

The following items are a collection of mathematical explorations developed for Georgia Tech's Math 1507. They are all formatted with Maple V. Release 4. These worksheets are ready to use, without much prior knowledge of Maple. As you read through them, you simply have to press ENTER to perform the calculations, and if you don't know Maple already you will easily begin learning how it works. After reading through a given worksheet, you can generate your own models and alternative scenarios by cutting and pasting Maple code. In each worksheet a model is introduced with a description of the content and of the level of presentation. These may be down-loaded onto your computer as text files, opened with Maple, and saved as active worksheets. Alternately, you may configure your Web browser to launch Maple as you choose a file.
