<p>hey which is the best book Math IIC
thank you</p>
<p>Barrons is little tough than actual but good if u want to get overprepared. PR accurately prepares u.</p>
<p>Has anyone used McGraw-Hill for IIC?</p>
<p>Get the sparknotes test prep books. They are the best and closest to the real thing.</p>
<p>Barron's and PR are both good. Use Barron's if you have a lot of time to study and are willing to prepare a little extra... if you do, the test will be no problem.</p>
<p>yeah like they said barrons kind of overprepares u. btw are the stuff in there such as cis ever tested in the exam?</p>
<p>most people say barrons overprepares but I found it easy enough. Maybe its becuase I do HL Ib math but the stuff in it weren't killer. does anyone else feels this way?</p>
<p>if you're missing like 15 in a barron's test, what kind of score are we looking @ on the REAL one probably.</p>
<p>well I missed 20 on barrons and got an 800 on an actual Math IIC test by the college board...</p>
<p>How is Barron's harder so that ppl like you can get like 800s, but were missing 20? <em>curious</em></p>
<p>Well you know how the actual test has easy, medium, and hard questions? My friend said that Barron's only puts the "medium" and "hard" ones. Basically a TON of really hard things that test weird concepts you've probably forgotten (like cis, finding non-real roots, really weird probability stuff). It just takes a lot longer to get through the test. When I do a Barron's test, I usually barely finish, with just a minute or two to desperately go back to the (numerous) questions I omitted. But after doing several Barron's tests, then doing a Sparknotes test, I had TWENTY extra minutes after finishing the test, with no omits. And I ended up getting a raw score of 48: 2 errors.</p>
<p>Plus sometimes Barron's tests arcane math terms, like the latus rectum of a hyperbola, stuff that you have NO chance of getting right if you haven't seen the word before.</p>
<p>so basically...on the real one, there are more questions where you can rack up easy points/questions?</p>
<p>Yeah.</p>
<p>To pick a random Sparknotes practice test, and a random Barron's test,</p>
<p>Sparknotes #50:</p>
<p>Which of the following is the center of the conic section 9x^2 - y^2 - 18x + 4y - 31 = 0?</p>
<p>1,2
3,2
1,-2
-1,-2
-1,2</p>
<p>Which is pretty easy-- just complete the square, etc.</p>
<p>And Barron's #50:
What is the amplitude of the graph of y = a cos(x) + b sin(x)?</p>
<p>(a+b)/2
a+b
(ab)^0.5
(a^2 + b^2)^0.5
(a+b)*2^0.5</p>
<p>Which is considerably harder, IMO.</p>
<p>Yea. I am using Mc Graw Hill. It has wayyy too many mistakes. </p>
<p>In Barrons I heard they give calculator programs we can put into our calculators. Can anyone post them?</p>
<p>how do you do cis? or is that only tested in barron's?</p>
<p>those programs aren't really useful. just by looking at the barron's #50, i think the answer is d, am i right?</p>
<p>EDIT: cisx=cosx+isinx. you might want to search cis in mathworld to find some basic cis functions</p>
<p>I saw that on wikipedia...but I don't know how to do this one</p>
<p>(2<em>cis</em>50degs)^3</p>
<p>Yeah, that Barron's one was D.</p>
<p>And glucose-- that problem isn't bad at all. The rule with cis to a power, is the number at the front is raised to the power, and the angle measure is multiplied by the power number. So that would be 2^3 cis 50*3, or 8cis150degrees.</p>
<p>ok...what is the answer in terms of i...I got it to the 8cis150degs part...that is the easy part.</p>
<p>Cis(x) stands for cos(x) + i sin(x)... so 8(cos150 + i sin150).</p>
