This website provides a free calculation device, (The PolyTrig Calculator) in the online JavaScript and spreadsheet formats (Microsoft Excel, and OpenOffice Calc).  The online version is embedded in this webpage below this introduction.  If you want the spreadsheet version of the PolyTrig Calculator, scroll all the way down, beneath the online Calculator.

The PolyTrig Calculator carries out over 30 trigonometric calculations simultaneously, when the user enters numbers for the height and base of a right triangle.  This includes the triangle's: hypotenuse, perimeter, area, two acute angles in degrees and radians.  Based on the two acute angles, it calculates the sine, cosine, tangent, cotangent, secant, cosecant, and seven trigonometric identities.

  Description of: The PolyTrig Calculator, Created By David@TechForText.com, ©2010  
  This calculation device (the PolyTrig Calculator) carries out over 30 trigonometric calculations simultaneously, when the user enters numbers for the height and base of a right triangle. The Calculator has five sections, and many formulas in the conventional and spreadsheet formats.  
  Simple Three-Step Instructions: 1) Delete the numbers in the two white Input boxes below. (To enter or delete numbers, you must first left click with the mouse on the relevant, white input box.)  
  2) Enter the height of your right triangle in Input box A, and the length of the base in Input box B.  
  3) For calculated results; left click with the mouse on the yellow background, or on the calculation button. Scroll down to view results. (This page is about 6 computer screens from top to bottom.)  
  This is Input Box A, which is for the height This is Input Box B, which is for the length  
  of the triangle. (Altitude or Opposite side) of the base of the triangle. (Adjacent Side)  
  A= B =  
  Section 1) Calculations without the Trigonometric Functions  
A=The height of the triangle =  
      Area of Triangle =  
 

This is the height triangle. It is also the altitude or opposite side of the triangle.

    Spreadsheet formula for the above =A*B/2  
    H = Hypotenuse =  
      Spreadsheet formula for above =((A^2)+(B^2))^(0.5)  
  The dimensions of this right triangle are used for all the calculations performed by the PolyTrig Calculator. This includes, height, length of base and hypotenuse, and the size of angles a and b        
    Perimeter =  
      Spreadsheet formula for the above = A+B+H  
         
          B = Base (Adjacent Side) =  
  Angle a, radians = Angleb Radians =  
  Spreadsheet formula for the above =ATAN(A/B) Spreadsheet formula for the above =ATAN(A/B)  
Angle a Degrees = Angle b Degrees =  
  Spreadsheet formula for above =DEGREES(ATAN(A/B)) Spreadsheet formula for above = DEGREES(ATAN(B/A))  
    The rounding mechanism, presented below, is NOT for the above calculations.    
  All of the FOLLOWING calculated results are rounded to decimal places. You can  
  change this, by deleting the above number (in blue type), and entering the number of decimal  
  places you prefer. If you enter a number that is excessively large you might get rounding errors.

Software Requirements for the PolyTrig Calculator,

Links for the Free Downloads,

And Additional Information

 

Software Requirements

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

 

The JavaScript version of the PolyTrig 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.

 

 

Download Links for the PolyTrig Calculator In the

Microsoft Excel, OpenOffice Calc, and JavaScript Formats

 

Important note: Some of the downloads are in a zip folder, and they must be removed from the zip folder to function properly.  You can do this with the Windows cut and paste mechanism.

 

If you want the PolyTrig Calculator in the Microsoft Excel format, left click on these words.

 

If you want the PolyTrig Calculator in the newer 2007 Microsoft Excel format, in a zip folder, left click on these words.  Note, this requires Microsoft Excel 2007 or newer additions of Excel.

 

If you want the spreadsheet version of the PolyTrig Calculator that was used to create the JavaScript version left click on these words. (This is in Microsoft Excel format.)

 

If you want the PolyTrig Calculator in the OpenOffice Calc format, in a zip folder, left click on these words.  This requires the free OpenOffice.org software package.

 

Note: If you do not have Microsoft Excel, download the OpenOffice.org software package, because it is free and it is almost as good as the Microsoft Office suite.  To download go to www.OpenOffice.org or left click on these words.

 

If you want the online JavaScript version of the PolyTrig Calculator, in a printer friendly format, left click on these words.

 

If you want the online PolyTrig Calculator without background colors, in a printer friendly format, left click on these words.

 

If you want the two JavaScript versions mentioned above, in a zip folder, left click on these words.  Note, within the zip folder, there are separate folders for each JavaScript version.  Each of these folders contains two files, one for the calculation device, and the other for graphics.  If the two files are separated, you will not see the right triangle on the PolyTrig Calculator.

 

If you want the PolyTrig Calculator in all of the above formats, in a zip folder, left click on these words.

 

If you want a diverse assortment of calculation devices for algebra and trigonometry, go to the main website at www.TechForText.com/Algebra, This can be done by left clicking on these words.

 

 

 

Additional Information About The PolyTrig Calculator

 

The PolyTrig Calculator was created in Microsoft Excel, and it was converted to OpenOffice Calc, and with specialized software to JavaScript.  The spreadsheet formulas displayed on the Calculator, I created for Excel.  I did this with the Excel name mechanism, which defines letters or words in terms of cell designations, such as input boxes.  This provides the functionality of writing spreadsheet formulas using letters or words, instead of creating formulas with confusing cell designations, such as:=F12*G12.

 

You can copy, modify and use the spreadsheet formulas on the PolyTrig Calculator for your own needs.  However, these formulas will not function unless you define the letters with the Microsoft Excel name mechanism.  Most of these formulas will also function in OpenOffice Calc. 

However, formulas that have commas must be modified slightly.  This involves replacing commas with semicolons for OpenOffice Calc.  For example, this formula for Excel, =ROUND((A/H), L25) must be converted to =ROUND((A/H); L25) for OpenOffice Calc.
