Math II forumlas?

Test Preparation SAT Subject Test Preparation
1

<p>Haven't taken the test yet, and i was curious about the forumlas. Would you be expected to memorize them or will some be presented in the test for you (like the math section in SAT I)?</p>

2

<p>All the formulas you wouldn't think you needed to know --> Heron's, cofunction etc etc.</p>

<p>These are for better efficiency...of course you don't NEED to know them; you could reinvent the wheel each time by using a proof.</p>

3

<p>...or by plugging in values in a calculator.</p>

4

<p>formulas.....
know your sequence formulas. :]
know your conic formulas
know your trig identities.
and more i don't remember</p>

5

<p>Yes, use your calculator. It is your best friend. Although know the ones up there to a certain degree. You wouldn't want a 790 like me...</p>

6

<p>Trig identities, like pythagorean, cofunction, etc. are useful. Geometric Sequence/Series and Arithmetic Series/Sequence showed up quite a bit on November's test (3 or 4 questions, I believe), so the ormulas are most certainly worth studying.</p>

7

<p>^ The arithmetic/geometric were not necessary or even that helpful on the November test.</p>

8

<p>What do you mean? There was one question that asked for the mean of an arithmetic sum, another that asked for some term of an arithmetic series, and I think a few others...?</p>

9

<p>mean of arithmetic sum: 225/2 round. </p>

<p>The other arithmetic sum consisted of subtracting 4 twice.</p>

<p>The geometric sum could have been easily seen to become reduced to 0 (the pt was not to find a sum)</p>

10

<p>Pfft, well, I like my formulas <em>haughtily walks away</em></p>

<p>...but those are the better solutions, I'd say.</p>

11

<p>Lol, in June there was this one question that asked for the 44th term. Good luck doing that in 1 minute without a formula.</p>

12

<p>Hahahahaha! Good example, anhtimmy. Formulas FTW!</p>

13

<p>@ anhtimmy</p>

<p>44 term? You mean as in they give you two #s you find the diff (top # - former # divided by # of terms between them). This is for arithmetic. Then use the recursive/implied</p>

14

<p>it was like n(sub 5)= (bubbles)
d was (pumpkin)
find the 44th term.
something like that o_o
formulas are really helpful. the end lol</p>
