sablefoxx Posted January 24, 2008 Share Posted January 24, 2008 Let me first say that THIS IS NOT CHEATING my AP physics teacher actually kept some of these to give to future students. DO NOT use these to solve problems, use them to check your answers! If its a half-way decent math class you'll get graded on your work not the answer. Anyway ever have a hard time remember all those pesky equations in math? Or just don't want to do all the work yourself? Or just want to check your answer to make sure its right? Well the Ti-83 Plus is the greatest thing ever for this, most people think calculator programs are just for fun games, but you can also have it do a lot of the number crunching you don't want to! PLus its easy to do yourself, if you do have questions about the c0de just post them! Feel Free to post your own codes too! Here are some example programs i have made to cut down on busy work, with the added bonus of being able to use these while your taking the test itself! EQUATION: x=(-b±?(b^2-4ac))/2a *UPDATE* Made it so the program tests the user's input, working on version that can handle i's (not sure if its possible yet) goto 1 QUAD v1.1 Lbl 1 ClrHome Disp " INPUT" Disp "----------------" Input "A:",A Input "B:",B Input "C:",C If A = 0 goto 4 (b^2-4AC)->X If X=<0 goto 3 ?(X)->W -B+W->Y -B-W->Z Y/(2A)->G Z/(2A)->H goto 2 Lbl 2 ClrHome Disp " Answers," Disp " +B",G,G>Frac Disp " Answers," Disp " -B",H,H>Frac pause goto 1 Lbl 3 ClrHome Disp " ERROR! NONREAL" Disp " (-B+-4AC)!=",X pause goto 1 Lbl 4 ClrHome Disp "ERROR! A!=0" pause goto 1 NOTE: to get the '->' use the 'STO->' key above 'ON' the '>FRAC' is found pressing [MATH] [1] and you do not type out commands you must choose them from a menu, most can found in the CATALOG open by pressing [2nd] 0 Slope Finder (Y1-Y2)/(X1-X2): goto 1 SLOPE FIND v1 Lbl 1 ClrHome Input "X1:",A Input "Y1:",B Input "X2:",C Input "Y2:",D (B-D)/(A-C)->E ClrHome Disp "Slope=",E pause goto 1 I dont know if this counts as a 'fun' game but here is K1u's Guessing game on the Ti-83+ goto 0 GUESS v1 Lbl 0 ClrHome DelVar X DelVar Y randInt(1,100)->X Disp "I am thinking" Disp " of a Number" Disp "Between" input "1 and 100: ", Y goto 5 Lbl 5 If Y=X goto 1 If Y>X goto 2 If Y<X goto 3 Lbl 1 ClrHome Disp "You Win it Was", X pause goto 0 Lbl 2 Clr Home Disp "You Are Wrong" Disp "It is Lower then", Y pause goto 4 Lbl 3 ClrHome Disp "Wrong! Guess" Disp "Higher then", Y pause goto 4 Lbl 4 ClrHome DelVar Y input "Guess Again: ", Y goto 5 ------------------------------------------------------------------------------------------------------------------ / More to Below / ------------------------------------------------------------------------------------------------------------------ Post Your Own Too! And if you want one made for a certain equation post the equation and i will do my best to help you out! Be sure to share them with a friend! Knowledge is Free!

deleted Posted January 24, 2008 Share Posted January 24, 2008 In Scotland (Dont know about anywhere else but it will probably happen) before the Exams, it is Mandatory to Empyt the Calculators memory before entering the Exam Room.

sablefoxx Posted January 24, 2008 Author Share Posted January 24, 2008 In Scotland (Dont know about anywhere else but it will probably happen) before the Exams, it is Mandatory to Empyt the Calculators memory before entering the Exam Room. Sorry to burst your Bubble Slightly. Not here, the teach actually said we could use them if we wanted, but if not archive the programs, this will save them even if the memory is wiped, then unarchived them during the test (but i do not encourage cheating) Alternately install 'Mirage OS' this hides any installed program (in the archive as well so emptying the memory wont erase them) unless you type in a password Quote Link to comment Share on other sites More sharing options...
Famicoman Posted January 24, 2008 Share Posted January 24, 2008 I've been whipping up these programs for years. Really come in handy. Quote Link to comment Share on other sites More sharing options...
Fireproof Posted January 24, 2008 Share Posted January 24, 2008 @ DarkBlueBox same here with my old school, do they check your program list or do they only check to see the "cleared" screen. Because if it is just the screen all you need to do is archive the program and it won't be deleted. Then Un-archive when you need to use it. Not that I would ever condone cheating. . . . .

Razor512 Posted January 29, 2008 Share Posted January 29, 2008 the quadratic solver doesnt work no matter what problem i enter in it says ERR:NONREAL ANS and if i go to goto it takes me to the line ?(b^2-4AC)->X edit never mind, it only seems to do simple ones and not the ones we normally get in class Quote Link to comment Share on other sites More sharing options...

So its basically the program only works (and the calculator for that matter) if: ?(b^2-4AC)->X Where b^2-4AC does NOT equal less then 0 Quote Link to comment Share on other sites More sharing options...

metatron Posted January 30, 2008 Share Posted January 30, 2008 The only cool stuff worth doing is using it to connect to an old modem and going on IRC or use it to fuck with alarm systems. Quote Link to comment Share on other sites More sharing options...
sc0rpi0 Posted January 30, 2008 Share Posted January 30, 2008 I've been making these programs for years now. Good that you posted them though since most people [as far as I know] don't have a clue how to make them. Quote Link to comment Share on other sites More sharing options...
skolor Posted February 12, 2008 Share Posted February 12, 2008 Yeah, I remember righting stuff like this. For those of you who have your calculators wiped. . . Some place there is a program that works kind of like virtual PC/VMware for the calculator, so that it only formats a portion of it. Don't remember where to find it, but if you really wanted that little bit of advantage (as opposed to, you know, going out and studying instead of spending the time writing this stuff/finding it online). . .

natural_orange Posted February 12, 2008 Share Posted February 12, 2008 i've been doing this for a long time. especially making programs just to store notes and equations that are confusing. you can do some kool stuff with the pxl-on, pxl-off, pxl-change, etc. find the slope and y-int, solve quadratic equation etc. Quote Link to comment Share on other sites More sharing options...
pants123 Posted April 9, 2008 Share Posted April 9, 2008 You know, its much easier than that. I wrote one just recently for the quadratic equation that was simply: PROMPT A PROMPT B PROMPT C DISP (-B+?(B^2-4AC))/(2A) DISP (-B-?(B^2-4AC))/(2A) If A=0, then you get a divide by zero error. If the answer is imaginary, it will display if your calculator is set to display imaginary numbers (Go to MODE to set those settings).

sablefoxx Posted May 12, 2008 Author Share Posted May 12, 2008 Hello i saw your thread on programs for Calculators. I need the following: A program that gives me (DX+E)(FX+G) when you enter the numbers for variables A,B, and C into the equation AX^2+BX+C if D x F= A and E x G= C and E+G=B. Pretty much, in my 10th grade math class, we are simplifying trinomials. I failed our last math quiz and would like to bring my grade back up on Wednesday when we have a test. I have a TI-83 Plus. The best thing you can do is study for the next test a program is only helpful for checking your answers to keep that in mind. Also, you won't learn anything if i give you the program straight up, so here is some sudo code, try to work through it and look at the other examples for help. If you get stuck post the code and we will try to help you out. Anyway from your description you'll need to do something like this: ClrHome Input "A:",A Input "B:",B Input "C:",C AX^2+BX+C if D x F= A goto if E x G= C and E+G=B goto disp (DX+E)(FX+G) Quote Link to comment Share on other sites More sharing options...
Phredsir Posted May 13, 2008 Share Posted May 13, 2008 I have to say I passed math class only because of these programs. they saved my life. Also my friend and I had program offs to see who could make the best program to do certain problems. I got really good at it I even made a few simple games.
