About Trig Calculator
Trig Calculator is an application that simplifies the process of calculating missing angles and lengths of regular and irregular triangles.
Includes a Chord calculator for solving circle segments.
Also features a calculator for solving regular polygons.
Let the application do all the hard work for you - no need for frustrating calculations using Trigonometry.
Simply enter 2 elements of a regular triangle and the application solves the missing elements for you.
Simply enter 3 elements of an irregular triangle and the application solves the missing elements for you.
Simply enter 2 elements of a circle segment and the application solves the missing elements for you.
Simply chose a polygon shape and enter one other known value to solve the missing elements.
Ideal for school children, students, machinists, carpenters, engineers, other tradesmen, or the general public, wanting to solve triangles,chords and regular polygons simply and efficiently.
The application uses Pythagoras,Trigonometry,Calculus, Cosine and Sine rules and simple deduction to give you all the answers you need.

Added a new tab to calculate missing values of regular polygons.
Regular Polygons are shapes in which all the sides and all the internal and external angles are equal.
Triangles,Squares,Pentagons,Hexagons,Heptagons,Octagons,
Nonogons,Decagons,Undecagons,Dodecagons,Tridecagons and Tetradecagons can be solved by entering one known value of Side length, Perimeter, Area, Circumcircle Diameter or Innercircle Diameter.

1.1
Feb 26, 2012
Added a Chord calculator to evaluate circle segments given two known values.
The calculator has Chord, Arc Length, Included Angle, Sagitta, Apothem and Radius.
By entering any two values, the remaining values are calculated using a combination of trigonometry and calculus.
This version also enhances the functionality of the Regular and Irregular triangle calculators, by increasing the values of known elements that can be entered to solve triangles.
The old version was restricted to values of 500mm, but the new version now allows values up to 999,999.999mm to be entered to solve the missing elements.
