<p>I'm gonna be taking math 2 (physics and chem also, but no calc) on saturday, and I was wondering what programs to load up on my TI-89 Titanium.</p>
<p>Any ideas? ticalc.org has tons of programs, but I'm pretty new to the 89 and I'm not sure whats needed for math level 2.</p>
<p>Sorry to hijack your thread, but TI-84s are allowed, right?</p>
<p>Yes.</p>
<p>Back to the math programs...</p>
<p>I had the SAT_OS program.
But it turns out, I didn't need it at all.</p>
<p>Unless you are freaking out and forget all the formulas, you won't need it.</p>
<p>Is it ACTUALLY an OS, or just a program?</p>
<p>I'm not too keen on replacing TI's firmware (even though it's supposed to be easy to undo).</p>
<p>It might do some good, I only got 690 on the bluebook (still kinda happy), mostly due to forgetting trig formulas and not having enough time on some long winded algebra problems.</p>
<p>I recall writing some programs of my own that solved quadratics, found distance between point and a line, and a few other things. None of it was really necessary, but it saved a couple seconds... and with Math2 being more of a time crunch than anything i guess it helped</p>
<p>Biggest suggestion is just get to know your calc well...</p>
<p>1) Make sure you are in radians if you don't see a degree sign
2) Learn to use matrices to do things like kramer's rule or to solve systems of equations
3) Understand that your calculator uses doubles and/or float variables to store numbers... thus, some value raised to the 95th probably won't compute... that doesn't mean the answer doesnt exist: find a pattern
4) Congrats on knowing the Combination / permutation formulas... but now it is time to use n P r and n C r</p>
<p>I hardly use a graphing calculator , and from what bco09 says...i think i might be fine with a scientific calculator...
anyone care to disagree?</p>
<p>As to what programs to use on the graphing calc. , Barrons seems to have a whole chapter dedicated to it... (u might want to check it out, if u havent already)</p>
<p>SAT_OS is just the name of the program. lol</p>
<p>R-DNA, you will need a graphing calculator; it makes your life a lot easier</p>
