<p>^But studying can make you better…programming wont help you at all unless that type appears on the test…in the 10 minutes that it takes to program a couple of things (and hope that those things appear on the test), you can totally understand how trig works.</p>
<p>For your problem, its just (4C1)<em>(4C2)=4</em>6=24…no formula needed, dont waste your time programming…ill teach you how: So you need 1 plumber out of 4, so its 4C1=4 ways to choose that 1 plumber…you need 2 trainess out of 4, 4C2=6 ways to choose the 2 traniness out of 4(theres a C thing on your calc)…</p>
<p>multiply for 24 as your answer</p>
<p>Of course this is assuming that the traninees are not distinct (which in most cases it is).</p>
<p>If they are distinct, its 4<em>4</em>3=48 (its usually not 48 unless they specify that the two tranee positions are distinct, which in your problem it doesnt).</p>
<p>Remember choose=order does not matter (in your problem it does not), permutations=order does matter.</p>
<p>where is the space button on the calculator?</p>
<p>On my calculator, a TI-83+, to make a space I press ALPHA then 0</p>
<p>Thanks Cricket. Yeah I’m usually alright with those type of problems but somehow I messed up and got 25 instead of 24, so I was wondering if there was a fool proof formula I could use.</p>
<p>To be completely honest, I’ve taken math all the way up to precal (which i took this year as a junior) and have had 1 good teacher so far. The other teachers I’ve had just briefly brush over stuff until the kids that are math whizzes get it and assume the rest of the class understands. So rather than relearn most of Geometry and Precal, I’d like to know any possible shortcuts. And teachers aside, I suck at applying math concepts that I already know. I’ve managed to pull off a B in every math class I’ve had but that’s because I could learn the material for the test without normally having to synthesize prior knowledge.</p>
<p>What formulas/stuff (for lack of a better word) are crucial to know for the SAT I?</p>
<p>Hey, recently I realized that it is possible to program in computers, and I really like programming but have no idea how so today I was just looking things up on the web about programming in calculators and the example they used was the heron’s formula. That gave me an idea…I want to create programs for the math section of the SAT. The purpose is to learn programming but if I am going to learn, I might as well make useful programs that can serve as a backup if I freak out during the tests and forget formulas. Anyway, I want to create a program for arithmetic and geometric sequences, but I do not want to make two separate programs, I want to make the kind of program where there is a menu, and I can go to either arithmetic menu or geometric. How do I do that?</p>
<p>u can just press prgrm which is right next to the apps key i believe and ull ahve 3 columns. in these columns are for ONLY programming. by scrolling down or going over to the next column, you will find the stuff that you need… good topic.</p>
<p>these also work on ti 84 silver or no?</p>
<p>Woah you guys kept my thread alive for a while now. :)</p>
<p>bump for those taking the sat tomorrow, i guess :D</p>
<p>Hey! I’m really glad I saw this thread! I had the same question I posted earlier today. I found this free SAT app for graphing calculators earlier this week and it seems to have a lot of what I need during practice ([SAT</a> Operating System For TI-83+ And TI-84+ for Mac - Free software downloads and software reviews - CNET Download.com](<a href=“http://download.cnet.com/SAT-Operating-System-For-TI-83-And-TI-84/3000-20415_4-75448635.html]SAT”>SAT Operating System For TI-83+ And TI-84+ - Free download and software reviews - CNET Download)). What do you guys think? Anyone ever use this one?</p>
<p>It has geometric sequences and circles, which tend to get me when I’m in a hurry, so I’m going to go ahead and use it.</p>
<p>Has anyone actually found these programs useful when taking the SAT or SAT II? Does it save time</p>
<p>Is Orthocenter on SAT? Not the Subject Area, just the Standardized one.</p>
<p>awesome 20char</p>
<p>Has anyone actually found these programs useful when taking the SAT or SAT II? Does it save time</p>
<p>I would not recommend them. I could finish most of the questions before I finish typing the numbers into the program.</p>
<p>Besides, if you understand the concept of the what you are essentially programming, you will no doubt know how to do the question.</p>
<p>The only one I found useful Quadratic formula.
Heron’s formula is a quick program, but you never have to use it.</p>
<p>Thanks so much elaslawek ! This will help me so much! But could you give me a more detailed explanation for these programs. As in what do they solve? Thank you!!!</p>
<p>Distance between 2 Points </p>
<p>Prompt A
Prompt B
Prompt C
Prompt D
Sqrt((A-C)^2+(B-D)^2)–> E
Disp “Distance =”
Disp E
Stop</p>
<p>Program : Midpoint</p>
<p>Prompt A
Prompt B
Prompt C
Prompt D
(A+C)/2–> E
(B+D)/2–> F
Disp “X Midpoint=”
Disp E
Disp “Y Midpoint=”
Disp F
Stop</p>
<p>Those two programs are basically exactly what they solve for: Distance between 2 points and the midpoint between 2 points. If need be, you can change them to: </p>
<p>Distance between 2 Points</p>
<p>Prompt “X1”, A
Prompt “Y1”, B
Prompt “X2”, C
Prompt “Y2”, D
Sqrt((A-C)^2+(B-D)^2)–> E
Disp “Distance =”, E
Stop</p>
<p>Program : Midpoint</p>
<p>Prompt “X1”, A
Prompt “Y1”, B
Prompt “X2”, C
Prompt “Y2”, D
(A+C)/2–> E
(B+D)/2–> F
Disp “X Midpoint=”, E
Disp “Y Midpoint=”, F
Stop </p>
<hr>
<p>There are a plethora of programs you can create such as a radical simplifier.</p>
