HGG's Mathprogram v1.0 for TI83 and TI83(Plus)

These programs HGGMAIN HGGTRIG HGGVECTO HGGDIST HGGFACT HGGSOLVE: required (HGGSAVE ALUNMATH: optional)

have the following use

  - Calculate Angles, Sides, Area etc of triangle (HGGTRIG)
  - 2D-Vector applications,addition, subtraction, dot product etc. (HGGVECTO)
  - Distance midpoint fomula for 2D garphs and other usefull linear formula applications (HGGDIST)
  - Primnumber check, Primfacots and all factors (HGGFACT)
  - Solves quadratic and cubic equations (real and complex answers)
    a linear system (up to 10 Vars) and a one or two variable sytem of any equation(s) with theroretical up to 90 solutions
  - HGGMAIN is the Menu
  - HGGSAVA is an extra program, to conserve contents of real Vars (see my Homepage www.geocities.com/hggehrke/)
  - ALUNMATH simply calls HGGMAIN (a link so that you can access my program more easily)

A detailed discribtion of my programs can be found on my homepage (www.geocities.com/hggehrke/)

The programs need a lot of memory (8800). This is more than a third of the RAM of a TI83.
But each program works also on its own (Thus if you only want to use the triangle functions, you just need HGGTRIG etc.)
