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.
