<p>sorry, i am just teasing, but math is about what you know, i don't htink they ask much about prime numbers, good luck everyone</p>
<p>Newbyreborn, I would disagree. I've taken the SAT-I for real twice and done about 7/10 of the Ten Real SATs and I don't think I've ever taken one without at least one prime number question on it.</p>
<p>To everyone who asks, "Isn't that kind of cheating?", please read the whole original post. Thanks ;)</p>
<p>I agree with claret quilty . . . I don't think that having a list of primes will help you much at all.</p>
<p>Putting prime numbers into an 83 isn't cheating. However, using the 89 on the Math IIc, lol man that's just streching the limits of morality (even though everyone does it). </p>
<p>Seriously, any program is allowed on the calculator. For AP tests, some people put a huge amount of information on their calculator. Perfectly legal to their rules.</p>
<p>FYI, you are explicitly NOT allowed to have a dictionary in your calculator. Any math program is fine, including a list of prime numbers... Any proctor who tells you you can't have programs is flat out wrong, and you should call them on it. I'm always amazed how poorly informed the proctors are...somewhere in this forum is a story about a proctor who said students were NOT allowed a calculator at all. Fortunately whoever posted that note had with him/her a list of allowed item. You are, by the way, allowed to have a backup calculator, too.</p>
<p>That said, I can't remember ever seeing a prime number problem in which you needed a prime bigger than 23. It's pretty simple to memorize primes up to, say, 31. Anybody see a problem that required something higher than that?</p>
<p>i dont get the part about a 'HUGE tip' that raises your score 10 points.</p>
<p>Well.. to raise 10 points.. you only need to get "one" more problem right, so if u get one more problem by using the prime number lists, or if you can save the amount of time needed to solve the problem, it basically means you just raised your score by at least 10 points..</p>
<p>That is, of course, if you were going to be getting that particular question wrong.</p>
<p>Even if you were going to get it right, u would save time to solve the question since you have pirme numbers on hand and that will enable you to solve other problems..</p>
<p>i've been wondering if programs are cheating..it's something i've seen people do at my school on math tests, hiding stuff in the program section, and that is definitely cheating.
but the college board website doesn't say anything about programs..? maybe because they know it couldn't help you that much..the prime number thing is going to be useful on 1 or 2 problems at most, if that.</p>
<p>Programs are not cheating, however, you definetely do not need them.
You are also not allowed a calculator on the verbal section, so having a dictionary on your calculator and using it would involve big risks, and if you get caught, well...you probably don't want to think about that.
Anyways, my point is just that you don't need a calculator. I scored 800 math in 7th grade, it's mainly algebra, a little trig, not very much advanced stuff, and certainly easy to calculate in your head. I've heard the new SAT will be harder though I still doubt the need for programs on your calculator.
anyways, all primes greater than five are of the form 6x+/-1 so if you really needed to, you could check pretty easily</p>
<p>thanks for the tips....anything else I could put into my graphing calculator that would be useful?</p>
<p>a few games just in case you finish early :D</p>
<p>i haven't actually put those on my calc yet, since i'm not taking those APs until next year, so i really don't know if they're any good.</p>
<p>With the 89 you can use the built in factoring thing. It helped me for one problem in the whole Blue CB book. The problem was (x^3)(y^2)=1296 Find one of those variables, or something like that.</p>
<p>The dictionary is at ticalc.org. A triangle solving program may be helpful if you know trig. Did anyone else here do a problem in the blue CB book, 8 reals, where you felt you had to use more advanced trig, that the SAT isnt supposed to test?
P796, #20.
I am referring to the problem where there is a rhombus, and you are supposed to find the ratio of one diagonal to the other. It's in one of the later tests, 7.</p>
<p>Here is the problem specifically:
If the five line segments above are all congruent, what is the ratio of length AC (Not shown, a diagonal) to the length of BD (a diagonal shown)?
The drawing is a rhombus with one diagonal drawn in, and that diagonal, BD, and all the sides are congruent. What is the ratio of the larger diagonal to the smaller?
I put in side lengths, and deduced the angles, and then used law of cosines to determine the length of the larger diagonal.
Here is the math, say 4 to plug in:
32-32cos(120)=48 squarert(48)= 4sq.root(3) =length of larger diagonal. Smaller diagonal is 4. so its large/small=root 3 over 1.</p>
<p>Julius, you likely cannot use a calculator on AP Bio. The calc study cards are probably not worth looking at during the test.</p>
<p>I actually like the idea of saving some prime numbers in the calculator. It can't hurt me, so why not.</p>
<p>Popping in distance and midpoint can't hurt, either, in case you blank out.</p>
<p>or you guys could just earn your scores all by yourselves</p>
<p>I took the PSAT and got 80 math not using a calculator (I forgot to bring one! LOL) but then yeah, I agree I haven't seen a SAT I math problem that requires knowledge of primes beyond 30.</p>
<p>Oh man. I got a 780 on math, and the one problem I got wrong was about primes. I'm bitter.</p>
