This website provides an Integral Calculus Calculator that solves basic integrals, and also illustrates the steps on how to solve integrals yourself.  The online version is presented below.  For the Excel and OpenOffice.org versions scroll all the way down, beneath the online integral Calculator.

Delete the numbers in the four light-green boxes, and then enter your own numbers.  To obtain calculated results left click on the yellow background or on the Calculate button.

Instructions for the

Integral Calculus Calculator

The integral calculus calculator is very easy to use. Just delete the numbers in the four light green boxes, on top of the calculator, and enter your own numbers.  For the online version left click on the yellow background, or press the calculation button to obtain calculated results. For the Excel and OpenOffice versions, press the enter key or left click with the mouse on the yellow background.

If you want to see the steps and related mathematics, needed to solve the integral yourself, scroll down to the lowest section of the Integral Calculus Calculator, which is all green.  This green section of the Calculator illustrates the step-by-step solution with the numbers you entered, (in the light green boxes on top of the Calculator).  This makes it easy to practice solving a basic integral.  However, if you are not engaged in the formal study of basic calculus, or are not at all familiar with calculus, you probably will not be able to understand the steps presented by the illustrations, with out help from a mathematics instructor.

Number Crunching Ability of the

Integral Calculus Calculator

The integral calculus calculator in all three formats, online, Excel, and OpenOffice, can calculate extraordinarily large or extremely small numbers, with OVER 300 digits.  Numbers that have many digits are displayed in scientific notation.  The letter E is used to designate scientific notation.  The online version uses a lowercase e, and the Excel and OpenOffice versions uses an uppercase E.  This format is illustrated in the following examples.

Examples of the Display of Very Large Numbers

By the Integral Calculus Calculator

1000000000000000000000 is displayed as 1e+21.  The 21, with a plus sign, (+) represents the number of decimal places after the first digit.

1456789666666890000000 is displayed as 1.45678966666689e+21. The 21 represents the number of decimal places after the first digit.

Examples of How Very Small Numbers

Are Displayed By the Integral Calculus Calculator

0.000000000000000000001 is displayed as 1e-21. With this example, 21 with the minus sign represent the number of decimal places after the decimal point.

The number 0.0000000000000000000067987 is displayed as 6.7987e-21.  The 21 with the minus sign (-) represent the number of decimal places after the decimal point.

Astronomically large Numbers, and the

Integral Calculus Calculator.

When large numbers, with over 305 digits are calculated by the online version of the integral calculus calculator, the result displayed is infinity.  When the result is negative, the calculator will display

–infinity.

With the Excel and OpenOffice versions large numbers with over 306 digits, will result in an error message, such as #NUM! or #VALUE!

Infinitesimally Small Numbers and the

Integral Calculus Calculator

When calculated results are infinitesimally small, (smaller than 1e-309), the integral calculator will display a 0 (zero), as the result.  If infinitesimally small numbers are entered into the light green boxes, you might get an error message, or the calculator will consider the number to be 0 (zero.)

When There Is No Calculated Result

When n (which is an exponent) is not a positive or negative integer, or zero, A and B must be positive, if not there is no calculated results, based on real numbers.  For example, if you enter n= 1.01, A= -2, and B=1, the calculator will display No calculated result.  If you perform such calculations by hand, it becomes obvious why there are no calculated results, based on real numbers.

My Name is David Alderoty, and

I Designed and Built this Website and the

Integral Calculus Calculator

I can design and build user-friendly software based calculation devices for arithmetic, accounting, algebra, trigonometry, correlations, calculus, etc.  I can create attractive calculation devices for your website.

I can also create communication forms with submit buttons, for websites.  This can include forms with built-in calculation devices.

I generally make these devices in the Microsoft Excel, OpenOffice.org, and the JavaScript formats, but I can work with other spreadsheet formats besides the above.

I write instructions for the devices I build.  I can also write instructions for software and computer devices created by others.  I can also write advertising for your products or services.

For a detailed list of all the services I offer, see www.TechForText.com For a list of all my websites see www.David100.com

If you need my services, you can call me at (212) 581-3740, of e-mail me RunDavid@Verizon.net.  You can also send your message in a website communication form, by left clicking on these Words.  For conventional mail My address is 345 W. 50th St., APT 10D New York, NY 10019.

If you are a great distance from my locality, or are in a foreign country, this is not important.  I can provide these services worldwide, because the software and websites I make can be delivered through the Internet to any locality.

I can provide the services mentioned above on a fee-for-service basis, or possibly based on permanent or temporary employment.  My resume is online at: www.David100.com/R
