AutoGrapher PSP

AutoGrapher is an application to assist calculating Algebra 1 and a small portion of Geometry. It is made in Lua by 10$man.

This was submitted to the PSP Genesis Competition 2011.

Features

Factor a list of Polynomials and solve them for 0 (10 polynomials at a time to be exact, value has to be set on your computer).
Factor a single polynomial that you input on your psp.
FOIL (or Distribute) like un-factoring.
Find the Volume and Surface Area of: Cube, Rectangular Prisms, Cylinders.

Beneksturun Theorom.

Developer noted that you must have your PSP set to 1.50 if you are using a PSP1000.

Goto Graph.
Goto Beneksturun.

Settings.

Goto Formulas> Cube, enter the value of the height and width and it will give you the answer automatically.

Same steps apply for Rectangular Prism and Cylinder.

From your computer navigate to your PSP and locate the folder /PSP/GAME/AutoGrapher/System/.

Open GRAPH.LUA using Notepad or Notepad++. Scroll down until you see

---GRAPHS GO HERE---
y1=-x^3
y2=x+1
y3=x^5

Now insert your formulas.

Then start AutoGrapher> Goto Graph, and you will be able to move the tracer.

From your computer navigate to your PSP and locate the folder /PSP/GAME/AutoGrapher/System/.

Open POL.LUA in Notepad or Notepad++. Scroll down until you see

num1[1]=16
num2[1]=28

num1[2]=20
num2[2]=36

num1[3]=2
num2[3]=-8

num1[4]=-3
num2[4]=-28

num1[5]=-19
num2[5]=48

Lets say your problem is

X^2+16X+28

Set each of the num1 num2 pairs like this:

set num1=16
and num2=28

Then run the application to get the answer, if it stays 0,0 it is prime.

Goto Quick Solve Factoring Polynomials on your PSP and enter in the equation. For example,

2X^2+7X+5

Set:

value1=2
value2=7
value3=5

Use the Left and Right button to change the number; Down and Up button to change the values.

Confirm then wait for it to tell you Done or Prime.

D-Pad Up/Down - Choose between option, Change value (Polynomial)

D-Pad Left/Right - Move tracer (Graph), Change number (Polynomial), Change vlaue (Formulas)

Cross - Perform the marked action, Confirm

Start - Go to menu

Developer noted it should work on PSP2000.
