Quadratic Tools

About

This directory of 7 programs was written for and on an HP48, but is compatible with an HP49, thanks to HPConv, an excellent program to convert HP48 objects to HP49 objects. This is just a VERY simple package of 7 programs that I made (in a very short amount of time) to find the roots of quadratics.

• SOL
  Solves for y, given A, B, C, and x.
  Usage: A B C x SOL
• YSOL
  Solves for x, given A, B, C, and y. Note that this is in testing, still.
  Usage: A B C y YSOL
• ROOTS
  Finds the discriminant, analyzes it, and finds the roots of a quadratic.
  Usage: A B C ROOTS
• DISCR
  Finds the discriminant and analyzes.
  Usage: A B C DISCR
• COMPL
  Completes the square. Note that this is in testing, still.
  Usage: A B C COMPL
• VERTX
  Finds the vertex of a quadratic. Note that this is in testing, still.
  Usage: A B C VERTX
• CURV
  Finds the curve of a parabola based on three points (A,B), (C,D), and (E,F).
  Usage: A B C D E F CURV
