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 (Apps). ==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. * Graph. * Beneksturun Theorom. ==Installation== Author noted that you must have your PSP set to 1.50 if you are using a PSP1000. ==User guide== ===Menu Options=== * Goto Graph. * Goto Beneksturun. * Goto Polynomial. ** Quick Solve Factoring Polynomials. ** Solve Already Input Factoring Polynomials. ** FOIL Polynomials. ** Go Back. * Goto Formulas. ** Cube. ** Rectangular Prism. ** Cylinder. ** Back. * Credits. * Settings. ===Finding Volume and Surface Area=== 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. ===How to use the graph=== 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. ===Solving 10 Polynomials at a time=== 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. ===How to use Polynomial Quick Solve=== 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. ==Controls== 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 ==Compatibility== Developer noted it should work on PSP2000. Tested on: PSP Brite TN-D <br> PSPGo <br> PSP Slim 5.00m33-6 <br> PSP Phat 5.00m33-6 <br> ==Changelog== '''v1.5''' * Polynomial solver should work fine now. * UMD quick start. * Other small fixes. ==Credits== Thank you to w00tguy123 for helping with the Graph. ==External links== * Official website - https://code.google.com/archive/p/autographer * Wololo - https://wololo.net/talk/viewtopic.php?t=5223&start=20 * Wololo - https://wololo.net/2011/04/24/autographer-genesis-compo-entry [[Category:Lua applications on PSP]] [[Category:PSP Genesis Competition 2011]]
