FE 'tkGooie' Utilities

A Menu of
Tk script CODE
for some

'MATHtools'
utilities

(FE = Freedom Environment)

The GUI interface of a 'tkGooie' app
that demos a proof of a theorem by Thales,
one of the first statements and proofs of
a theorem, circa 2000 BCE.

OVERVIEW of 'MATHtools'
--- in the FE 'tkGooies' system :

A description of the FE 'tkGooies' system is available via a 'tkGooies' Description page. That page points out that the 'tkGooies' are a collection of utilities in categories such as

  • 3Dtools
  • AUDIOtools
  • FILEmanagers
  • IMAGEtools
  • INTERNETtools
  • MATHtools
    (with submenus for additional math Tk scripts)
    • MATHed [ucation] menu
    • ODEtools menu
    • Converter-Selector tools (in 'SELECTORtools' menu below)
  • PLOTtools
  • SELECTORtools
  • SYSTEMtools
  • TEXTtools
  • VIDEOtools
  • Tk-GUIs EMBELLISHED demos
  • Tk-GAME menus
  • Tk-WIKI demos
  • MORE

Just below is a list of links to pages that present the source code of a collection of the 'MATHtools' in the FE 'tkGooies' system.

and CODE for 'MATHtools' 'tkGooie' scripts)

Some MATHtools sub-groups:

  • Also there are some MATH education tools in the MATHed toolchest of the 'tkGooies' system

  • Also there are to be some ODE Solver tools in the ODEtools toolchest of the 'tkGooies' system

  • Also there are some CONVERTER-Selector tools in the SELECTORtools toolchest of the 'tkGooies' system

The following 'MATHtools' Tk GUI's are on my 'to-do' list:

  • tkNonlinEqnSolv1or2 -
    to put a Tk GUI on some nonlinear algebraic equation(s) solving procedure.
    Reference: page 'Newton-Raphson Equation Solver' at wiki.tcl.tk
    --- but I may try a 'binary-search' solution method --- for one equation
    in one unknown, and for two equations in two unknowns. Maybe three someday.

  • tkLinEqnSolvUpTo4 -
    to put a Tk GUI on a linear algebraic equation(s) solving procedure
    --- for up to 4 equations in 4 unknowns, say.

  • tkFamilyReunionCalc -
    to calculate who owes how much on a house rental for a week, for members of a family reunion --- with some members staying different numbers of days --- with some rooms being valued higher than others --- with some family members getting a discount (such as children or the low-earning/low-saving uncle)

  • and probably a few more math-tools someday
