Trisolve is now officially completely remodeled and doctored. It is a function that will solve an entire triangle given three total sides or angles - just put zeroes for the values you don't know. I took off the extra baggage and made this into a function, which is useful for precalculus, geometry, and many other applications.

This program is intended to solve systems of equations involving trig functions with 1 or 2 unknown angles, but is also an easy way to handle other types of equations, such as exponential or logarithmic equations or complex trig equations with one unknown. It uses the TI Solve function, but is easier to use since there is no variable list to enter. Angle domains can be entered simply by choosing quadrants from a menu. Restrictions for linear variables, such as x>0 and y>0 and y≤ 5, can be entered. Angles can be displayed in radians (in terms of pi when possible) or degrees. All entries can be edited. Solutions are copied to the Home screen and are stored under the variable names. Several examples are included.

Works for SSA (two triangles) and even if there are no solutions, the program will continue to run so that it gives at least partial results for the benefit of the user. Note: It still indicates, though, if there truly are no real solutions.
trigplus.zip33k02-05-11File is not ratedTrigPlus: Triangle Solver
TrigPlus is a triangle sovler for oblique and right triangles. It gives data on specian geometric segments (median, altitude, angle bisector), area, and in/circ-scribed circles.

trigsolve.zip1k02-08-28File is not ratedTrig Solve
Trig Solve allows the user to enter in a known trig value and the quad that it's in and have the calculator figure out the remaining five trig values. Depending what quad you choose, it accounts for positive and negative. Answers are displayed in a matrix in exact and approximate values. Is a very fast way to solve trig values accurately!
trigsolv.zip2k00-03-02File is not ratedTrigonometric Function Solver and Grapher v1.0
This program, while similar to trigfunc I wrote earlier, graphs the angle the user inputs on the unit circle and gives the coordinates of the point of intersection on the circle. It also solves the triangle formed by the angle, giving the values of all the sides and the remaining angles. Then the user can continue to show the all the trig values for that angle. It will display all trig functions, including the inverse. Any angle works for this program (in degrees or radians).

This is a simple triangle solver. Several bugs have been fixed in this version.
trisolve25.zip2k04-10-20File is not ratedTriSolve v.2.5
TriSolve can tell you every detail about a triangle if you enter the values for the 3 sides. It can calculate: angles, medians, bisectors, altitudes, inscribed circle area, radius and circumference. The only thing it can't do is circumscribed circles (because I'm too lazy to look up the formulas:) GREAT FOR TRIG!
trisolve2.zip1k00-06-06File is not ratedTriangle Solver
Solves for the sides and angles of any triangle. See readme.
trisolve3.zip2k00-08-28File is not ratedTriangle Sover
Give this program any three sides or angles and it will find the other ones and the area of the triangle! It's that simple! It will even give both possibilities, if they exist, when given two sides and an angle opposite on of them!
trisolver.zip1k99-12-25File is not ratedTriSolve
Given 3 parts of a triangle, solves for the other 3 and calculates area, includes ambiguous case.
trisolve.zip5k10-07-23File is not ratedTriSolve v1.7
10 years of bug-free operation! Using the laws of sine and cosine this program will solve the area and remaining angles and sides of a triangle when you give it any three (except 3 angles). If the triangle has two possible solutions (some SSA triangles) it gives you both also. Angles are shown in normal degrees and degrees/minutes/seconds. Version 1.7 has a brand new bug fix and smaller code.
triworks.zip1k01-03-14File is not ratedTriWorks
This is a simple program that allows you to use the Triangle Inequalities Theorem to solve whether a written triangle would work in the real world, by using the lengths of the sides. For use in Geometry.
trix.zip3k02-11-29File is not ratedTriSolve v2.00 & TriK v1.99
Tri Solve 2.00 will solve for ANY triangle you input. You have the choice of solving SSS, SAS, SSA, AAS, and ASA triangles. It will solve for multiple triangles (i.e. in SSA and SAS triangles.), and use the angles and sides you provide to solve for the missing angles using the Law of SInes and the Law of Cosines. All angle calculations are in degrees. This is a great program, and it saves a lot of time. TriK 1.99 uses the same basic code as TriSolve, and solves for the area of triangles using Hero's Formula. All of the above applies, including solving for multiple triangles.
tri.zip1k05-01-28File is not ratedTriangulos
Este programa resuelve triangulos rectangulos sabiendo solo un angulo y un cateto o la hipotenusa e incluso sin saber el angulo
tsimplfy.zip5k02-05-27File is not ratedTrig Simplify

tsolveq.zip3k05-12-10File is not ratedTrigonometric Equation Solver
This program is a trimmed down version of Tsolvgrf(). The graphing part of the program has been removed. It includes the latest upgrade to Tsolvgrf(), which speeds up the process of displaying results. The program finds all solutions, within a chosen domain, of a trigonometric equation. Results are shown first in radians, in exact form as a multiple of pi, when possible, rather than decimal form. They can also be displayed in degrees. The default domain is 0--2pi, but it can be changed. The equation can be edited, either before or after solving. The solutions are copied to the home screen.
tsolve.zip7k03-05-18File is not ratedTrigonometric Equality and Inequality Solver v. 2.00
This function allows the user to solve an equality or inequality with a single variable in a limited domain. This allows the solution to be free of the @n symbol so it is much easier to read and comprehend than the solution the built-in solve function would give. While the domain of the solve function can also be limited, it will still return some solutions with @n in it and this function eliminates that entirely. -- The function should now work properly with any and all approximations, along with fixing the problem of not returning all correct solutions of certain trig functions in AMS 2.08
tsolvgrf.zip4k05-12-10File is not ratedTrigonometric Equation Solver and Grapher
This update of Tsolvgrf() speeds up the process of displaying results. The program finds all solutions, within a chosen domain, of a trigonometric equation. As an option, the function can be graphed to display the solutions. Results are shown first in radians, in exact form as a multiple of pi, when possible, rather than decimal form. They can also be displayed in degrees. The default domain is 0--2pi, but it can be changed. The equation can be edited, either before or after solving. The ranges for the graph can be changed or zoomed. The solutions are copied to the home screen.
