<p>Is it expected that the test-taker has the whole trig table/unit circle memorized? (i.e. Do you need to know all the values for sin 30, sin 45, cos 60, tan 135, etc.?)</p>
<p>i would like to know as well.</p>
<p>You do have a calculator if you forget...</p>
<p>I realize that, but the calculator does not give values like √2/2... it gives it in decimal form.</p>
<p>just memorize it, it's really not that hard.</p>
<p>it'll make other, non-SAT things easier too</p>
<p>Yeah, just memorise it. It's not that difficult. You really only have to memorise the first quadrant, and if I were you, I would memorise it in radians.</p>
<p>You should be able to convert 30, 60, 90, etc. to radians in your head, using logic, so it doesn't matter too much.</p>
<p>
</p>
<p>Well the TI-89 does, and you can still do the problems in decimals anyways.</p>
<p>You don't have to but it's good in the long run.</p>
<p>By the way, if sqt2/2 was on the test, just plug it in to your calculator!</p>
<p>Just save all the values in your calculator. Go to programs and just type in all of them and save them....</p>
<p>Those are pretty easy values that you should know.</p>
<p>If you haven't used them enough to memorize them or to easily derive them within a few seconds, I would question your readiness for the test.</p>

<p>I do know those, but I don't know cot (225) off the top of my head, nor do I know sec(135). Yeah, with some tweaking and using the reciprocal identities I could get it, but I'm wondering if memorizing these types of things are necessary for the Math IIC test.</p>
<p>I don't know, but it probably shouldn't take too long to just memorize it.</p>
<p>In the time it's taken you to post in this thread you could've memorized it.</p>
<p>is it necessary to know the values on the test?</p>
<p>Exactly, akati^. I don't want advice on whether or not I should memorize it -- I want to know if it is necessary for SPECIFICALLY THE MATH IIC TEST TO HAVE THAT INFORMATION MEMORIZED.</p>
<p>can someone answer please?</p>
<p>bump please...i want to know so i can prepare for math 2c</p>
<p>The unit circle isn't too bad, just learn the pattern and keep practicing it. Now with some problems, like [Sin(315)<em>Cos(315)]/Tan(135), Barron's will even say to just plug it in, and convert the fraction answer choices to the one closest to what your calculator says. Of course, for something like Sin(30)</em>Cos(60), if you know that it's just 1/2 * 1/2, then that's quicker than plugging it into your TI.</p>
<p>MEMORIZE ALL OF THEM.... You need to know them. Case closed...</p>
