TotalTrig is the most comprehensive trigonometry program for the Palm on the market today. It is comprised of a unit circle and two triangle solvers, a comprehensive set of trigonometric definitions and relationships, and a full set of graphs of each of the trigonometric functions. TotalTrig is like having a trigonometry textbook with you at all times, except only better!
The solvers that are built into TotalTrig are an Arc-Length Solver that determines properties of the sector of a circle, a Right Triangle Solver that determines properties of right triangles, and an Oblique Triangle Solver that solves all other types of triangles.
Comprehensive help is available in TotalTrig showing how to use the program while providing insight into the trigonometric background behind each screen.
TotalTrig has several features that set it apart from the competition. Unlike many, if not all, of the other Palm programs on the market, it is the only one of which the author is aware that correctly solves oblique triangles with one obtuse angle (an example of this is found in the documentation). It is the only program of which the author is aware that takes the area of a triangle as an input in order to calculate the other sides and angles of either an oblique or right triangle. Perhaps its most useful feature is its ability to actually draw the triangles, circles, and segments after the values are calculated. In this manner the user is able to readily see how changing values changes the actual geometry.
For students of trigonometry, TotalTrig is unsurpassed in its completeness. Not only does it correctly solve any triangle, but many definitions and relationships are readily available in a readable and useable format.
The definitions and relationships that are available are:
One Angle Definitions and Relationships:
Basics
Reciprocals
Inverses
Pythagorean
Double Angle
Half Angle
Quadrants
Symmetry
Rarely Used
Two Angle Relationships:
Addition
Subtraction
Product
General Relationships:
Law of Sines
Law of Cosines
Area Formulas
Newton's Formulas
Mollweide's Formulas
Many relationships in TotalTrig are not commonly found in trigonometry textbooks today, yet sometimes using one or more of these relationships or equations can make the difference between solving a problem and failing to arrive at a solution. TotalTrig has screens explaining the exsecant, versine, coversine, and haversine identities. Other screens explain Newton's formula, Mollweide's formula, and how the area (K) of any general triangle is calculated.
TotalTrig also provides graphs of the trigonometric functions. A small sampling is shown below.
