This is a simple Lua application for the PSP that has 7 useful mathematical functions built into it.

User guide

These are the 7 functions built into the program:

• Convert equations from standard form to y-intercept form.
• Convert equations from y-intercept form to standard form.
• Find the determinant of a 2x2 matrix.
• Find the determinant of a 3x3 matrix.
• Find the solution to a system of 2 equations with 2 variables*.
• Find the inverse of a 2x2 matrix.
• Simplify a fraction.

(*) This means that it finds the intersection of two lines in standard form

Controls are displayed on the screen.

Changelog

Version 0.2

• Got rid of the find slope and y-intercept option and replaced it with the equation conversions (standard to y-intercept and vice versa). The standard to y-intercept still says the slope and y-intercept, though.
• Added function to find the inverse of a 2x2 matrix.
• Added function to simplify any fraction into its simplest form.

Version 0.1

• Initial Release.
• Features:
  • Find slope and y-intercept of a line in standard form.
  • Find determinant of a 2x2 matrix.
  • Find determinant of a 3x3 matrix.
  • Find the solution to a system of 2 equations with 2 variables.
