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.

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
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
