<p>ughh. why did i get barrons?
i couldn't answer like 8 of them, and then i got 4 wrong. </p>
<p>what does that translate to? the book shows some weird rounding thing, so i got confused. and what does that probably translate to on the actual test, assuming that i keep studying, since I took this one without any studying.</p>
<p>700+ for Barrons is basically 800.</p>
<p>Sparknotes and (obviously) CB tests are more accurate. I've been getting consistent 800's, which you probably would too.</p>
<p>@mallika7122.. i omitted 9 and got 4 wrong and that was a 730 exactly so your score is probably 740 which is pretty good for barrons apparently.</p>

<p>use the formula
800-10(44-X)
X being the raw score, if its more than 44, you got a 800.</p>
<p>you got a 730 :]</p>
<p>Ok, so.....is a 760 on PR fairly "close" to actual test score?
And do colleges see the percentiles when you take these things, or just the numerical score?</p>
<p>How do you put formulas into your calculator? Please help!</p>
<p>Is the curve normally really harsh for this test? I didn't read the whole thread so I apologize if this has already been asked.</p>
<p>I have a TI 84 and I was wondering if there were any programs I could put on it to help me? I've found programs for TI-89s, but not for 84s
Thanks!</p>
<p>lol just put in formulas, so u dont need to memorize</p>
<p>i would put the quadratic formula, distance formula, and the arithmetic/geometric series in your calculator, maybe even law of cos?? but i think the first two would save the most time</p>
<p>umm another calculator question..
ti 84+
how do u convert from rectangular form to polar form and vice versa on teh calculator</p>
<p>like 2cis50=1.29+1.53i
and -1-2i=2.24cis243</p>
<p>thanks...</p>
<p>How do you put the arithmetic/geometric series on your calculator?</p>
<p>btw:
for the polar to rect. question use the R-->P and P-->R buttons</p>
<p>^do we have to know a lot abotu polar to rectangular..like conversions, cuz then i have some more reviewing to do......</p>
<p>i think all you need to know for polars is that the coordinates are (r,theta) and.. </p>
<p>(x,y)</p>
<p>x=r cos(theta)
y=r sin(theta) ... yes? no?</p>
<p>occasionally they go a bit further . . .like on the MAY test.</p>
<p>one question said x = 3 cos (theta) and y = 5 sin (theta)...which equation is equivalent (and the equation was for an ellipse)</p>
<p>badically, use your calculator</p>
<p>but storing formulas is just a pain and wont help that mcuh. instead, graph things, plugg things in, and use common sense</p>
<p>tan(theta) = y/x</p>
<p>sqrt(x^2 + y^2) = r</p>
<p>How do you input formulas into a calculator( specifically TI-83)?????</p>
<p>(a+bc)/(we +f) = g where e<em>F</em>G does not = 0</p>
<p>which is equal to w</p>
<ol>
<li>(a+bc -fg)/(eg) 2. (a+bc - g)/(e) 3. (a-bc+fg)/(eg) 4. (a+bc-f)/(eg) 5. (a+bc-eg)(fg)</li>
</ol>
<p>i knwo for conversion u use >rect, >polar..but i dunno how to set it up....like what do i but b4 thsoe signs on the ti-84+</p>
<p>PLEASE help a brotha out. =D</p>
<p>the answer is 1. not that hard, id be so happy to see that on the test tomorrow. just solve for w with algebra.</p>
