<p>The FOIL program won't work if you're dealing with 2 variables, so beware!!!!!!!!</p>
<p>Also, I think that memorizing the formulas instead of using calc programs is much better. It usually saves valuable time on the test, and besides, the math section isn't that hard anyway.</p>
<p>I know, its not for substitution/elimination when u have two variables. It was meant for questions like (1X - 7)(3x + 9)</p>
<p>erasmus.. it doesn't save time with stuff like distance formula especially where you're working dilligently on that stuff to avoid + or - plus. So it helps for some things. This isn't to override memorizing basic formulas but it helps for certain things that take a while and helps you avoid careless mistakes.</p>
<p>a couple questions... how do you get the equals sign and the quotations?</p>
<p>Equal sign - math key. Its either math or second math.
For a " - its on the bottom right of your calculator. Alpha Something.</p>
<p>also for like disp "distance ="
where can i find the distance key?
there is also a program where it is area = and some other ones</p>
<p>nevermind... i think you just type it....
thanks for the programs</p>
<p>If something is in quotes, that means it shows you that when the program runs i.e. it it just references for you. like for the quad solver, it says discr = which tells u wut the discriminant is, just incase u need simplest radical form.</p>
<p>the triangle area formula does that work for any triangle as long as you have the three sides?</p>
<p>like is it the law of sines and cosines?</p>
<p>i can’t find the store key, I’m using a TI-84 Plus</p>
<p>Yes the triangle area works for any three sides of a triangle.
Its called Herons Forumla.
Whoremongter - Sorry I use a ti-83+ so I cant help,.</p>
<p>on the ti84 plus the store key is right above the on/off button</p>
<p>… So, this is basically cheating? Haha.</p>
<p>How is this cheating? You are allowed to have anything on your calculator during the Math section. Personally, all I have is quad program and foil, but anything is allowed.</p>
<p>Program : Sum of X Consecutive integers</p>
<p>Disp “Sum of”
Input S
.5S(S+1)–>A
Disp “Sum of 1 to S=”
Disp A
Stop</p>
<p>i dont understand this program. what does the output when you put it in your calculator tell you?</p>
<p>No! It’s not cheating! Barron’s even tells you how to program some things like DPL…</p>
<p>Oh, wow. I did’nt know you could do that. Whoops.</p>
<p>I’m using a scientific calculator for Math I. It’s totally like having unprotected sex.</p>
<p>@briguy: it gives you the sum of all numbers from 1 to a number S.</p>
<p>programming things is my favorite way of doing well on math contests. sometimes I can’t figure out the answer on very difficult questions and I just start programming like mad during the contest haha. it’s freaking awesome.</p>
<p>anyone else have requests? I feel bored and I want to write some. I write games too, but they’re too long to post.</p>
<p>can anyone do a geometric and arithmetic series and sequence one? thanks</p>
