| **statlitegi.zip** | 92k | 07-05-16 | | **StatLite 1.02.1 Graphical Interface** This is an upgrade to StatLite 1.02 it differs from the original because it uses a graphical interface to input and output the data; StatLitE v1.02 is a TI-83,84 style command-line distribution function package. Running normcdf(-infinity,36,35,2) returns 0.691462461274, full 12 decimal accuracy. The built-in TI cumulative normal is only accurate to 8 decimals. StatLitE is also a 12.3k alternative to the full 317k Stat LE Flash App. Included are pdfs and cdfs for the binomial, chi-squared, F-distribution, geometric, normal, Poisson and Students t distributions. The inverse normal cdf is also part of this package. Inverse chi-squared, F-distribution and Students t use the built-in solve function. Those three inverses run VERY SLOWLY! Supporting functions are the beta, incomplete beta, regularized beta, error function, complementary error function, double factorial, rising factorial, gamma, natural log gamma, lower incomplete gamma, upper incomplete gamma, and regularized gamma. |

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.

| **triman.zip** | 52k | 04-03-17 | | **TRIMAN Ultimate Triangle Solver (version 4.3.7)** TRIMAN Ultimate Triangle Solver (version 4.3.7) I was frustrated that I couldn't find a program that could solve ANY triangle problem--some require you to choose SSA, SAS, etc.; most do not solve using area; and so on--so I wrote my own program: TRIMAN Ultimate Triangle Solver. TRIMAN Ultimate Triangle Solver, does it all. Simply input ANY information you know about the triangle and the program will automatically give you a solution. If the values you enter do not make a triangle, you will be told. If you don't have enough data to be able to solve the triange, you will be told. If there are two solutions, you will be given both. All triangle solutions are given in two ways: approximate and exact. Additionally, the answers are stored as variables for easy usage in your later calculations. If you're looking for a one-stop solution to be able to solve any triangle problem, then look no further than TRIMAN Ultimate Triangle Solver. *The program has been tested extensively and I have been using it personally for two years without problems, but if you do find a bug, please let me know by sending an email to davidfreeman2@netscape.net. I also welcome emails with suggestions for future improvements. |
