TI-83 Plus BASIC Math Folders Organized
Posted by Michael on 22 May 2008, 01:20 GMT

We are pleased to announce that after much work, all of the TI-83/84 Plus BASIC Math programs have been organized into subfolders. This was done in order to improve the usability of our archives. We hope the new subfolders will allow users and authors alike to more quickly locate programs. Each file takes nearly a minute to organize, so this effort requires many hours of work. For that reason, feedback is encouraged in the comments as to if you want this kind of organization expanded to other directories in our archives (we have partially organized 83+ BASIC games so far as well).

The new subfolders are:

• Algebra (math/algebra) - Everything algebra-related goes here, from algebra solvers to algebra programs and equation solvers, synthetic division, etc.
• Arithmetic (math/arithmetic) - General, "everyday" math. Greatest common divisors, modulo arithmetic, addition, multiplication, fractions, long division, square roots, etc. Pure numerical programs would fit here (no algebra or higher math).
• Factoring (math/arithmetic/factoring) - Factoring and prime number programs. A subset of arithmetic, this folder is devoted to programs which factor numbers (but not equations - those would be under Algebra), and prime number checkers.
• Calculus (math/calculus) - Derivatives, integrals, and everything else calculus including Newton's method, slope fields, Riemann sums, and more.
• Converters (math/converters) - Conversions, between units (e.g. feet to miles), bases (decimal to binary), and everything else including Cartesian to polar coordinate converters, temperature, and more.
• Finance (math/finance) - Financial programs, including interest calculators, mortgage calculators, etc.
• Geometry (math/geometry) - Geometry programs, such as distance calculators, polygon programs, ellipses/parabolas, volume, surface area, etc.
• Graphing (math/graphing) - Graphing programs which don't fit in any other category (statistical graphers would be in statistics). Examples include X= graphers, inequality graphers, piecewise graphers, etc.
• Linear Algebra (math/linearalgebra) - Linear algebra, including matrices and vectors. Determinants, cross-products, matrix minors, simplex tableaus, kernels, etc.
• Quadratic (math/quadratic) - Quadratic solvers now have their own special folder. This segregation means that we can now accept quadratic solvers again, because they no longer clutter up other types of programs. We have 111 quadratic solvers as of today!
• Series/Sequences (math/series) - Series and sequences, including Fibonacci programs, arithmetic/geometric series/sequences, summation, etc.
• Statistics (math/statistics) - Statistics, including statistical tests, statistical graphs (distribution curves, pie charts), geometric means, probability (coin flipping), regressions, variance, box and whiskers graphs, etc.
• Suites (math/suites) - All in one math suites spanning more than one category of math (e.g. Bob's Ultimate Formula Pack, Algebra/Geometry helpers, etc.). These are perhaps the most popular category and now you can choose the suite that best meets your needs.
• Trigonometry (math/trigonometry) - Trigonometry, including all things triangle-related. Trig functions (sin/cos/tan), laws of sines, Pythagorean triplets/theorem, etc. Note however that Pascal's triangle is not here but in Algebra because it merely is a geometric representation of binomial expansion, an algebra concept.
• Misc. (math/misc) - Everything else that doesn't fit in one of the above folders.

If you are uncertain where to upload your programs, browse through the folders. If you don't see anything existing that is similar, please use this article as a guide. If anyone notices a program in an incorrect folder (some are of course debatable), please comment on this article.
