The Basic Integral Calculus Generator is designed for students that know the basic method of solving a simple integral, but need practice to avoid errors, and to increases speed and efficiency with these calculations. The Basic Integral Calculus Generator is not designed to teach calculus, or to explain related mathematical principles. If you need this type of instruction, you should do a Google search for videos for basic Calculus.
The Basic Integral Calculus Generator is very easy to use, as explained in the following four steps.
Step one) The user enters two numbers in two white input boxes, located on the upper portion of the Basic Integral Calculus Generator. The user can choose any numbers he or she prefers. The numbers can be randomly chosen, and they can even contain decimals.
Note-One) The software generates twelve practice exercises with the numbers entered by the user. If these numbers are more than two or three digits, the arithmetic might be quite difficult. If you want arithmetic that is easy, enter single digit numbers.
However the basic Integral Calculus Generator is designed to handle numbers with many digits. When numbers are extremely large or small they are displayed in scientific notation, using the letter e. An example of a large number in this format is 4.4218961132108144e+116, and an example of a very small number displayed in this format is 2.5746740266666662e-130 these numbers were actually calculated by the software. If they were written out in conventional notation, they would be well OVER 100 digits in length.
Note-Two) The numbers that the user enters are applied to twelve integrals, as values for a and b, such as The software automatically solves the twelve integrals as soon as the numbers are entered, but the calculated results are initially concealed from the user.
Step two) After entering the numbers in the white input boxes, scroll down and you will see 12 integrals, which progressively increase in difficulty. The student's job is to solve each integral with pencil and paper. A calculator can be used for the arithmetic.
Step three) After attempting to solve each integral, the student checks his/her pencil and paper calculations, with the result calculated by the software. To do this there is a simple mechanism under each integral, consisting of a pink box with the letter N in it. When the user deletes the N, the software displays the calculated result.
Step four) For each practice session, change the numbers in the white input boxes, if you want a set of twelve integrals that have calculated results that are different than the integrals in your previous practice session. Keep in mind that multiple practice sessions are usually required to master a mathematical technique.
Step 1) Left click with the mouse on a blue download *link, for the Basic Integral Calculus Generator and a dialog box will open, with an option to save the file.
*Note the download links are located in the next subsection.
Step 2) Save the file on the Windows Desktop or in the Documents Folder, or anywhere else on your computer, where you can easily locate the file’s icon. Keep in mind that after you downloaded the file, you must locate the file's icon on your computer.
Step 3) The file's icon can be moved after downloading to any location on your computer, with the windows cut and paste function. You should move the icon to a location on your computer where you can easily find it. For most people, the best place to store these files is in the Documents Folder (also called the My Documents in some versions of Windows).
An alternative to the above three steps, is to download the Basic Integral Calculus Generator in a zipped folder. To do this left click on a link with the words: zipped folder. With this method, most browsers display the files icon as soon as the download is completed. Then you can use the Windows cut and paste function, to place the file anywhere you want on your computer.

Download Links, for the OpenOffice Calc Format
If you do not have Microsoft Excel on your computer, the best alternative is to use OpenOffice Calc, for the Basic Integral Calculus Generator. To do this, you must first obtain the FREE OpenOffice.org software package, which provides almost the same functionality as Microsoft Excel, Word, PowerPoint and Access. The OpenOffice.org software package is open-source, and you can download it from the following website: www.OpenOffice.org

The Basic Integral Calculus Generator was initially created in Microsoft Excel. To do this, spreadsheet formulas had to be created for each of the 12 integrals. The formulas were created by solving the integrals with symbolic notation, consisting of the letters: a and b. The values of a and b are defined when the user enters two numbers in the input boxes of the Basic Integral Calculus Generator. The input boxes, were defined with the Microsoft Excel name function, as a and b. If this was not done, the formulas I created would not be recognized by Microsoft Excel.
After solving the integrals in terms of a and b, it was necessary to modify the results, in terms of notation, to create spreadsheet formulas. For example, in the spreadsheet notation for Microsoft Word, and OpenOffice Calc, for multiplication the asterisk (*) is used, and for division the slash (/ ) is used. For squares, square roots, cube roots, etc. the following format in red type is used: , ,
If you want to see the twelve spreadsheet formulas I created, examined the Basic Integral Calculus Generator. Under each integral you will see the following words, with the spreadsheet formula: The spreadsheet formula for this calculation is
The spreadsheet formulas I created might look quite different than the conventional calculations used to solve integrals. However, once you become familiar with the notation, you will see that the formulas are mathematically identical to the conventional way of solving integrals.
Incidentally, with the technique described above, spreadsheet formulas can be created from most conventional formulas, or from almost any mathematical sequence, that can be expressed in terms of letters. However, when the spreadsheet formulas are written in terms of letters, the related input cells must be defined in terms of the letters. For example, a spreadsheet formula for area can be written as =L*W, such that L= length, and W= width. This formula requires that an input cell is renamed or defined as L, and another input cell is renamed or defined as W.
The mechanism That initially conceals the
results, as explained above, consists of a pink box with the letter
the student deletes the N, the calculated results for the integral, is
displayed. I created this mechanism with the IF FUNCTION ( IF( ) ) available in Microsoft
Excel, and other
spreadsheet software. Specifically, I created a conditional
statement for each
integral, consisting of the following: if there is an N in
Cellx, do not
display the calculated results, but if this is not the case display the
results. (Cellx is used in this explanation to
relevant cell on a spreadsheet.) The actual statement is not
conventional English wording. It is written as follows
=IF(Cellx= “N”, “ ”, (a formula for integral) )
The graphics for the Basic Integral Calculus Generator are the twelve integrals. Creating mathematical notation especially integrals, that will display on a website without imperfections is somewhat of a challenge. All of the websites I have seen to date display mathematics with less than perfect notation. Integrals and square roots are often displayed in a text format, using the characters on the keyboard. I actually use a format that is very similar to this to write spreadsheet formulas, but displaying mathematics in this way, is a less than optimal way of conveying mathematical concepts.
In theory, mathematical symbols, including integrals can be displayed on webpages with computer code, which is the same way that text is usually displayed. However, Internet browsers, as well as the operating systems used in modern computers, universally have the capability of interpreting computer code for text, but this is not the case with mathematical symbols. There is of course computer code that can display mathematical symbols, if the user has the appropriate software.
I have MathType version 6.7, and it can generate computer code that will display mathematical symbols, but I did not consider this an option, because the Internet browsers do not universally support this type of code, at this point in time. This will probably change over the next few years. My only other option was to use a graphics format, to display mathematical notation. This essentially involves formats that are similar to, or even identical to, the format used in digital photography. MathType, and even Microsoft Word, and Excel can be used to produce mathematical symbols in of graphic format.
I carried out a series of trial and error experiments, and I found that the best option is to use MathType, and configure it to produce high quality mathematical notation in the Graphics Interchange Format. Specifically, I set the controls in MathType to produce the GIF format at 360 dpi. I inserted the resulting graphics into the Microsoft Excel device, one integral at a time. I then reduced the size of each integral, and carefully placed it in the proper location on the spreadsheet.
Creating graphics that are larger than necessary, and reducing the size when inserting is consistent with good quality. Just the opposite is also true, creating graphics that are small, and increasing size when inserting is likely to result in a poor quality image.
I designed the Basic Integral Calculus Generator, and this website, in a way that would maximize efficiency and ease-of-use. The Basic Integral Calculus Generator has instructions placed next to related input cells, and it is laid out with a simple structure, with large fonts. The website similarly has large fonts, with a similar structure, and clearly written instructions. For example, the download links on this website contain precise wording, to prevent confusion, such as: If you want the Basic Integral Calculus Generator in the Excel format, left click on these words.
The website is on one long webpage. This provides the convenience of scrolling down or up, from one section to another, and it avoids the unnecessary complexity of pull-down menus, and links to go from one page to another. However, I provided a hyperlink table of contents as an alternative way of navigating the website.
Some of the material on this website is technical. Thus, for an optimum level of comprehension, the reader IDEALLY should have an advanced background in spreadsheets software, coupled with knowledge of programming concepts and calculus. However, I structured each sentence with the goal of minimizing confusion, and maximizing comprehension, for users with varying levels of technical knowledge. In this regard, perfection is never possible, because users come from diverse technical, cultural, and linguistic backgrounds.
I provided many headings and subheadings throughout this text. This allows the user to easily skip material that they find difficult, or uninteresting. The headings and subheadings are also displayed in the table of contents.
I write instructions for the devices I build. I can also write instructions for software and computer devices created by others. In addition, I can write advertising for your websites, products and services.
