This website provides ten free algebraic trigonometry calculation devices, in the online JavaScript, and spreadsheet formats. The online versions of the calculators are embedded in this webpage, below this introduction. If you want the spreadsheet versions, or additional information, scroll all the way down beneath the online Calculators.

Instructions

To use any of the ten Calculators enter numbers in the set of white input boxes, associated with the Calculator you are using. To enter or delete numbers you must first left click with the mouse on the relevant white input box. Each calculator functions independently, and numbers entered for one calculator do not cause calculations in the other calculators.

For calculated results, left click with the mouse on the background, (anywhere except on the white input boxes.) Alternatively, for the online JavaScript version you can press the calculation button, and for the spreadsheet version you can press the enter key.

Before all the numbers are entered into a Calculator, you may see error messages. If the user enters numbers that do not satisfy an equation error messages will also be displayed.

Each Calculator has an error checking device, which functions by substituting the calculated result into the unsolved version of the equation. If the left and right sides of the equation result in numbers that are equal, the device displays the words No error. If this is not the case, the device displays the word: Error.

Note: The embedded page (below) with the Calculators is equivalent to a 10 page document. To see all of the Calculators you must scroll all the way down.

If you want a printer friendly version of the Calculator left click on these words. (If you print the version presented below, Everything on this webpage will be printed.)

All the calculations for the error-checking are rounded to

decimal places. You can change this

by deleting the blue number (on the upper left) and entering

the number of decimal places you prefer. If you enter a number

that is excessively high you may get error messages when

there are no errors. are no errors.

The Software You Need for the

Algebraic Trig Calculators, and

Links to Obtain the Free Downloads

The Software You Need

The spreadsheet versions of the Calculators require either Microsoft Excel, or the free OpenOffice.org software package, which is available at www.OpenOffice.org. In addition, Microsoft Windows is required for the spreadsheet versions.

The JavaScript version of the Calculator can run on any operating system that has JavaScript support, but I only tested it with Microsoft Windows. In addition, the JavaScript version requires a browser that supports JavaScript. Almost all modern operating systems and browsers support JavaScript.

Technical Information, and How the

Ten Algebraic Trig Calculators were Created

The Ten Algebraic Trig Calculators were initially created in Microsoft Excel. The JavaScript versions were created from the spreadsheet versions. This involved a conversion process, with specialized software.

Spreadsheet formulas were created for each Trig Calculator. To do this the equation shown on the top of each calculator were solved for an unknown. Then, the resulting equation was translated manually into a format that is recognized by spreadsheet software.

For educational purposes, the spreadsheet formulas used for each calculation device are displayed directly on the device itself, near the location of the actual formula, which is not visible. You may copy and/or modify these formulas, and use them for your own needs.

The name mechanism, in Microsoft Excel, was used to define the meaning of each symbol used in the spreadsheet formulas. This involved defining letters in the formulas, in terms of specific input boxes. This method results in spreadsheet formulas that more or less look similar to conventional formulas. The alternative method uses cell designations instead of letters. Formulas created with cell designations do not look like conventional mathematical expressions.
