<p>I have been reading a lot of threads about how useful the Ti-89 is on the Math IIC test and i was thinking of getting it. But im taking the SAT IIC test on Jan. 22 and im worried if i have enough time to familiarize myself with the calc. Do i have enough time to get used to it??? Im really hoping to get a 800 on the test. Or should i stick to my Ti-83 that i have had for like 4 years?</p>
<p>the ti89 will help u a lot more than just this small test. </p>
<p>there is time but you should use the ti89 always from now on and get it asap. the more you practice, the more milliseconds you cut down =D. go ahead and get it.</p>
<p>Is it worth 150 $????? Like what functions does it have that is useful on the IIC?</p>
<p>there are a lot of coupons out there in the world. office depot has those $20 off coupons flying everywhere once in a while. </p>
<p>ok.. i'll just list some functions for u.</p>
<p>factor()
zeros()
czeros() <- complex zeroes
solve() <- works for most functions. you can use some basic programming keywords to make more complex problems. ie. solve(2x+4y=343 & 3x+4z=3242,{x,y})</p>
<p>dude, you can motherf'ing do this:
type this exactly as it is...</p>
<p>4x^3+23x^234 | x=23423</p>
<p>it'll immediately get u the result of this equation WHILE x =23423
the "|" means "while"</p>
<p>you can also go crazy and go for like
(define f(x) first and use the crazy copy paste feature)</p>
<p>f(x,y,z) | x=234 and y=245 and z=234</p>
<p>one of the best features of the ti89 is pretty print. it'll display whatever mathematical expressions you input in a nice clean format. such as when u type 3/4 it'lll give you a 3 over 4 with a bar inbetween. </p>
<p>calculus
d(-234234,345345x^34) <-this calculuates the 234234th antiderivative of 345345x^34
desolve()
limit() <- hope u know what this means
sum()
fMax() <- absolute max or min i think</p>
<p>ok i'm tired. out.</p>
<p>Ti-89 basically does 3 years of high school math for you. All you have to worry about is anything above pre-calc...</p>
<p>khalid889, are you freaking kidding me?</p>
<p>it can't even do geometry. </p>
<p>but it can calculate the almighty derivative to any degree. (displays them awkwardly sometimes tho). this probably saves a buttload of time on ap calc exam.</p>
<p>i heard that it can get u laid. i think the functon is "getmelaid()"</p>
<p>haha mediocretes.</p>
<p>"it can't even do geometry. "</p>
<p>***? are you telling me that you're worried about pythagorean theorem?</p>
<p>seriously what i meant was that any serious math up through precalc (factoring, taking derivs, etc...) could be handled by the ti-89.</p>
<p>nah, now i think of it, there is no point, it'll bring your score DOWN, i tried to learn to use it in 3 weeks, result without calculator 800
i thought getting the calc would ensure and 800
but got 780 :(</p>
<p>the ti-89 can do geometry if you buy the cabri package for it from ti.</p>
