<p>binomial expansion (what is the third term of (a+b)^4 )
or parametric equations
conics
and stuff
i'm looking throught the barrons and I'm wondering If I'm gonna have to know all that for the test. I dont want to waste time on unnecessary info.
Also, are there a lot of permutation/probabiltiy questions bc I suck at those no matter how hard I try to learn them</p>
<p>bump bump i wanna know this too...</p>
<p>You can just use Pascal's triangle for binomial expansion. It's really quite easy. They have had questions on both conics and polars, so know them if you want an 800, or at least know the basics. They usually have some basic probobility stuff, but it never really gets to hard. All that stuff isn't to hard to learn (at least, the basics of that stuff), so you might as well anyway.</p>

second the above, pascal's triangle. they wont' ask beyond 4 or 5, which is easy to memorize.</p>

parametric equations

never seen them. unlikely. would not study if you didn't have time.</p>

conics

make sure you nail circles, major minor axis, yes they do test stuff on this. expect at least 2 - 3 questions on conics. sometimes they ask you to find the equation of an ellipse after they give you the diagram on a cartesian plane. </p>

do try to learn, but hey. if you can't do it, i suppose that forms about 2 to 3, 4 at the max questions on it. most of it is basic probabiltiy, lke 10 red and 12 blue ball sin a bag, whats the probability of it not being red, or something like that. </p>
<p>your focus in learning should probabyl be functions, domain, range, recognizing them, sovling them, inverses... i think that's big.</p>
<p>Well... they can have some more interesting probability questions. On my test, they asked something like "the white car can't be on the far right and the blue car can't be on either end, how many possibilities are there" or something like that which is slightly harder, but not hard to learn. The hardests ones they ask are the ones where one object can't go some place and another object can't go somewhere else etc.</p>
