<p>How many calculators are you allowed to use?</p>
<p>Like, for instance, can I bring my TI-84, which I’m pretty comfortable with, and my TI-89, for tricky calculations and systems of linear equations?</p>
<p>You can bring multiple calculators. I usually have two (but not different calculators, one is just a back up).</p>
<p>You can have only one on your desk though.</p>
<p>You can bring either, as far as I know. You probably don’t need the Ti-89, though… if you know the math, a Ti-84 will suffice.</p>
<p>Wait, so I can’t use both simultaneously?</p>
<p>I have a question. Should we use rad mode or deg mode?</p>
<p>I just have a plain fx-82 :(</p>
<p>^^My Kaplan review book says to always keep it in degrees, so…</p>
<p>
</p>
<h1>No. :(</h1>
<p>
It depends:
for geometry question - it’s degrees; for trig equations/inequalities it could be either radians or degrees.</p>
<p>Does anyone have any great calculator programs or ideas for programs?
I have multiple formulas on my calculator, yet I do not know which are important and whether I should have other formulas</p>
<p>^^if anyone wants the programs of the formulas I use i can post them, they’re really easy to make.</p>
<p>^Could you please do so?</p>
<p>Instructions: go to program and create a new one. The first line press program, go to I/O press 8. New line. Then go to i/o press 2. Punch in the variables (Be sure to use commas to separate). Enter the formula in one line. Press enter. Press program go to disp in ctl then press second answer. It should look like this. Quadratic formula:
clrhome
prompt A,B,C
(-B+{-((b^2)-4ac)^.5,((b^2)-4ac)^.5})/2
Disp Ans</p>
<p>I raised it to .5 because I coulldn’t find the notation for square root. Also, if you’re unable to find a symbol, just go to catalog</p>
<p>This can be done for all formulas, same way of entering!</p>
<p>Get your hands on a barrons book. In the back, there is a section all about programs, and gives you step by step instructions as to how to enter them into your calculator and how to use them. Don’t worry, there were no typos there that would give you a messed up program.</p>
<p>Sorry, double posted by mistake (forgot to close window)</p>
<p>On the SAT II I brought my TI-89, TI-83, and a scientific Calculator.</p>
<p>I would just bring the 89. I brought the 83 for the batteries mainly, and I lent my scientific character to someone else.</p>
<p>
</p>
<p>Well, I must say that lending your scientific “character” to someone is quite noble 
Kidding aside, I’ve heard similar advice. I plan to take three (an 89, 84, and scientific) but with one graphing calculator and the solar scientific calculator as a backup.</p>
<p>hmm approximately how many questions require such calculators?
i have issues with calculators in general lol so i’ve been doing practice tests without a graphing calculator and it seems to be going alright…</p>
