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.

Software Requirements for the PolyTrig Calculator,
And Additional Information
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.
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.
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.
Additional Information About The PolyTrig Calculator
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.
