<p>Hello </p>
<p>What Graphic Calculator would you recommend ? for math ,physics and chemistry.
I'm not familiar with SAT. I have only taken 'O' level exam in UK so I'm not sure about the structure of the SAT. </p>
<p>thank you in advance!~</p>
<p>The one that you can make most use out of. Literally.</p>
<p>You cannot use a calculator on the SAT subject test in chemistry. About physics - I am not sure. On the math one and on the general one - you can.</p>
<p>However, do not buy a calculator just because someone tells you it’s good. After a certain very basic level, which the SAT requires, all calculators are equal. What matters is how you use them. On the SAT one of the most important factors is time, so take the calculator which you feel most comfortable working with. Don’t just buy a super powerful machine (Ti-89 for e.g.) without knowing how to operate it. If you spend 3 minutes in the search for the intersection button - that’s too much. And, although you have time till the exam, you’d better spend it on preparing for the test by solving problems rather than by learning a whole new technology inside out, which you are very likely to need only for a couple of problems.</p>
<p>That’s my opinion.</p>
<p>I use Ti-84, even though I also have Ti-89 and Ti-Nspire. Yes, the 89 and the Nspire are MUCH more powerful, but I know every little detail about Ti-84, so I decided not to risk losing time working with something that a knew relatively little about. ;)</p>
<p>Bottom line - use the calculator that you had for the O-levels. I am 99% sure that it can find the intersection between 2 functions. :)</p>
<p>I don’t think you’re allowed to bring a TI-89… Or are you? Besides that, it would be the best calculator to use.</p>
<p>TI 89 is allowed, and I’d say if you have one, you’d be silly not to use it…
About half of the SAT II is just “here’s an equation, solve for x,” and even if you have no idea at all of how to solve it, you can type it directly into the calculator and hit “solve…”</p>
<p>Interesting that they’ve loosened up on the calculators allowed. I wonder what that’s done to the average math score (as evidenced by clandarkfire’s post)?</p>
<p>For SAT Reasoning, a TI-89 is completely unnecessary, if you are very comfortable with it, I’d say go for it though. </p>
<p>For Chem, physics, no calculator is allowed.</p>
<p>A TI-89 still has drawbacks too, on the recent math 2 subject test there was a question asking for how many times two functions (one trigonometric, one exponential) intersected. TI-89 users just typed it in the ‘solve’ function and got 4 answers and a “Warning: more solutions may exist.” But for those other people that graphed it - there were clearly 6 solutions. So those 89 users that didn’t graph it to check the answer missed the question.</p>
<p>Here’s my recommendation.</p>
<p>(1) Most importantly use a calculator that you are comfortable with. This is more important than any features that a better calculator might have.</p>
<p>(2) If possible, and you have time, choose a TI-84 (or something comparable) to get comfortable with. This has the advantage of a large screen, more than enough graphing capability (which you may or may not use - never necessary), and some other nice features that will allow you to get certain answers more quickly than on a scientific calculator. In my opinion the TI-89 is overkill, and may actually slow you down unless you’re VERY experienced with it.</p>
<p>Best of luck!</p>
<p>Personally, I used a TI-84 and a TI-89 combo for the Math II and SAT tests. However, as many posters have already mentioned, this may be overkill for you if you’re not super fast at figuring out how to solve a problem.</p>
<p>The test taker, and not the calculator, makes a great score.</p>
<p>Bring an Asian Boy. Keep him in your pocket or something. “DO MATH.” I Kidd. TI-84 “Silver Edition,” because then you can play Mario in your spare time.</p>
<p>The best calculator is the most powerful one that you can effectively use (and is allowed). There’s no sense in bringing a TI-Nspire or 89 if you can’t use it… I think an 84 should be sufficient for almost all of it (heck, a scientific calc is probably enough), but there was one problem on the SAT Math II that I used my Nspire CAS for.</p>
