<p>wait barrons tells u how to program?
which book?</p>
<p>and all the programs mentioned so far…are they the essential ones?
any more?</p>
<p>when entering a program, how do u skip lines?
oh yah and when u go like
(-B+Sqrt(D))/(2A)</p>
<p>we gotta enter every single parathesis?</p>
<p>@Altamont:
geometric: (A is first term, R is ratio, N is number of terms)
</p>
<p>arithmetic: (A is first term, Z is last term, N is number of terms)
</p>
<p>@stuntburn: no programs are essential. you should be able to do all of those yourself (I’m a programmer and I got 800 on Math II without using my calculator)
and you need all the parentheses. press enter to skip a line.</p>
<p>wait, elaslawek, can your program be use for every calculators?</p>
<p>anyone know how to put programs on the ti-89?</p>
<p>Can someone explain
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 don’t really get what this would be used for. An example of a problem would be great</p>
<p>@xxLAJxx: TI-89 should be the same as TI-83 for programs… I think. I only saw my friend’s TI-89 once since we’re not allowed to use it normally.</p>
<p>@rk33: in my opinion, it’s a useless program with an extremely narrow application. if I were to program one, I would let you be able to input any arithmetic sequence. this one just asks for a number (let’s say 22) and gives you the sum of all integers from 1 to 22. useless. I would let you input a start value, an end value, and increment value, which would give the program some use (for arithmetic sequences)</p>
<p>So it’s like 1+2+3+4->22?</p>
<p>I think I can remember their being questions on the SAT somewhat like that but I don’t recall them being that narrow and starting from 1</p>
<p>how do u put this in to the calculator</p>
<p>Disp “D=”</p>
<p>where do u get the quotation marks and the equal sign</p>
<p>rk33: yes you get 1+2+3+…+S. useless though, since it always starts at 1 and increment is 1</p>
<p>quotes by pressing alpha then + sign I think. I don’t have a calc in front of me, but it sounds right. equal sign, press 2nd then math.</p>
<p>What’s the little i in the cone and sphere formulas?</p>
<p>Pi. There’s no Pi button on a keyboard</p>
<p>Is it possible for someone to make a program for recursive problems? I remember that there was a program in my math analysis book but it was written for the computer or something.</p>
<p>Btw, it is also good to have the law of sine on one’s calculator; it’s one of the quickest ways to solve for areas of triangles:
K=.5ABsinC (SAS triangles)</p>
<p>^Bit misleading, that isn’t the law of sines, that’s just another formula to find the area of a triangle using trig.</p>
<p>I know someone already posted a program for finding the sum of an arithmetic and geometric sequence but can someone make a program to find a specific term (i.e. 5th term of geo sequence)</p>
<p>any for combinations and permutations?</p>
<p>instead of programming, why not take the time to study?</p>
<p>^ I agree. Math is pretty easy.</p>
<p>^^ Not everyone is good at math.</p>
<p>Is there a formula for this type of problem?</p>

<li>The Acme Plumbing Company will send a team of 3 plumbers to work on a certain job. The company has 4 experienced plumbers and 4 trainees. If a team consists of 1 experienced plumber and 2 trainees how many different such teams are possible?</li>
