<p>I have several programs on my TI 83 for the Math IIC tomorrow (distance in 3d space, conics, universal triangle angles and side finder, etc.) Will the proctor make me clear my RAM before I take this test or is it legal to have programs on there?</p>
<p>it is entirely legal.</p>
<p>its perfectly legal to have programs. I have my ti-83 stocked with 3d distance, conics, and permutation formulas as well lol.</p>
<p>can you guys tell me where I could obtain such programs, that'd be really helpful!</p>
<p>I'm interested as well.</p>
<p>me 3 (tencharacters)</p>
<p>If you have barron's book, it has some usefull ones and you can learn to program more from that book. I have quadratic formula. Distance between two points in 3-d space. Perpindicular distance between a line and a point. Heron's formula for the area of a triangle. The angle created by two intersecting lines (acute angle) And the law of the cosines, one solving for the angle measure and another solving for the side oppisite of the angle measure. It is not that hard to figure out....</p>
<p>Make them yourselves!!! muahahahah</p>
<p>nah, that would be mean. try <a href="http://www.ticalc.org%5B/url%5D">http://www.ticalc.org</a> and look under math programs. I happen to use a ti-84 so its pretty easy to get programs. All my programs, however, were made today in a matter of 10 minutes by me myself and I. I like making my own programs for 3 reasons: They are relatively uncomplicated equations, it gives me a sense of self satisfaction, and provides a good review of the subject material. Good luck tomorrow</p>
<p>This works for the TI-83+</p>
<p>On your calculator, turn on and press the black button labeled PRGM. Go right until NEW is highlighted, and type in "DISCRIMINANT", which is what the following program solves for, given you know what A,B, and C equal. Type EXACTLY what you see. If you do it wrong, I can't help you. This program is extremely basic anyway.</p>
<p>:Prompt A,B,C
:B^2-4AC-->D
:Disp "DISCRIMINANT=",D</p>
<p>--> refers to the black button above the on button labeled STO-></p>
<p>Guys the test is designed so it can all be done by hand, or on a graphing calculator. Programs slow you down, I'm serious. Its funny, kids spend so much time trying to cheat (i know its not actually cheating but its close) rather than studying a concept than can be mastered in 20 minutes. I would suggest having a quadratic formula solver, which someone at your school probably has, thats it. Every problem can be solved in less than 30 seconds, there is a way to simplify everything, its the kids that always reach for their calculator that have problems and don't have time to go through the test a second time. Try taking a practice test and only reach for your calculator when you can't do it by hand, you will be surprised at how quickly you finish the test. I find it pathetic that kids have triangle solvers on thier calculators. If you just spent 20 minutes (it really only takes that long) you can easily remember the law of cosines and sines and solve the problem much faster than those kids who have to punch all the numbers into a program.</p>
<p>That smiley is just a capital D. I accidentally typed a smiley because each of the program lines starts with a colon and adding a D on the computer gives you a :D. But there is actually no space between the colon and the D on the last line.</p>
<p>:Prompt A,B,C
:B^2-4AC-->D
: Disp "DISCRIMINANT=",D</p>
<p>MIDPOINT FORMULA</p>
<p>:Disp "THIS PROGRAM CALCULATES", "MIDPOINTS"
:Disp "A=X1","B=Y1","C=X2","D=Y2"
:Prompt A,B,C,D
:(A+C)/2-->E
:(B+D)/2-->F
:Disp E,F,"=MIDPOINT","COORDINATES"
:Pause
:ClrHome</p>
<p>Dammit! I keep forgetting the computer does smileys!</p>
<p>MIDPOINT FORMULA</p>
<p>: Disp "THIS PROGRAM CALCULATES", "MIDPOINTS"
: Disp "A=X1","B=Y1","C=X2","D=Y2"
: Prompt A,B,C,D
: (A+C)/2-->E
: (B+D)/2-->F
: Disp E,F,"=MIDPOINT","COORDINATES"
: Pause
: ClrHome</p>
<p>Once again, those spaces at the beginnings of lines don't actually exist.</p>
<p>And finally, Logarithms.</p>
<p>: Disp "INPUT BASE"
: Prompt B
: Disp "TO WHAT POWER?","INPUT E"
: Prompt E
: (log(E)/log(B))</p>
<p>I actually have one more.</p>
<p>QUADFORM (Quadratic Formula)</p>
<p>sqrt=square root symbol on the calc aka. 2nd X^2 button</p>
<p>: Prompt A,B,C
: (-B+sqrt((B^2)-4(AC)))/(2A)-->X
: (-B-sqrt((B^2)-4(AC)))/(2A)-->Y
: Disp "ROOTS ARE",X,Y</p>
<p>Maybe these will inspire those who have programs on their calc to stop being so uptight and share the love. Honestly, taking 10 minutes to put just a few of the simple programs you have on your TI isn't going to hurt your score one bit.</p>
<p>hey tbry, I need to use the formulas because I wouldn't have enough time if i didnt use them. With these programs I can solve quadratic equations in a few seconds. I could defnitely get an 800 on the IIC with a lot of time. It also takes longer to do the law of cosines by hand than to do it out on a calc.</p>
<p>is there a formula sheet for the sat II math? how about for physics? if yes, anyone know where i could see them?</p>
<p>You guys can try my SAT OS program for the TI-83+ located here:
It may not contain all of the required equations for Math IIC, but it adds a nice solve() function to the 83+ (similar to 89) that you would otherwise not have.</p>
<p>If you do have an 89, the SAT_OS (89 version) can be downloaded here:</p>

<p>I might have repeated a few, and that's by no means a complete list of everu formula you might need to know, but it's at least some.</p>
