Test Preparation SAT Subject Test Preparation
1

<p>should i study cis cuz i heard they throw in like 2-20 cis q's per test
is there rlly that many? and such a range...</p>

2

<p>CIS as in cos + isin(theta)? I didn't see any of those types of questions, in either the prep book I used (Princeton Review) or on the actual test.</p>

3

<p>yeah i have PR and it doesn;t even touch it
cept in my pcalc honors class we did a unit on it cuz i aint studiyin it though</p>

4

<p>also anything on the imaginary number plane since that kinda has 2 do with cis shizzle stuff</p>

5

<p>No imaginary numbers on the Math II.</p>

6

<p>no? weird.
most prep books have imaginary number problems.</p>

7

<p>Math Level 2 has imaginary numbers. On one of the official released tests, there's a complex plane problem.</p>

8

<p>was it a cis problem
could u plz write down the problem and answer choices on here so i could see wat itss like</p>

<p>tanks</p>

9

<p>cis = just plug the thing in ur calculator. easszy</p>

10

<p>Oh, huh, I never came across any. Which prep books are you guys looking at? My mistake.</p>

11

<p>grade inflation must be rooting 4 the SA spurs..loser</p>

<p>anyways anyone with the collegeboard book willing to post the complex plane q</p>

<p>tanks</p>

12

<p>Oh, huh, I never came across any. Which prep books are you guys looking at? My mistake.</p>

<p>There was one problem with imaginary numbers in the first Math2 official test in the Math subject test official book released by CB.</p>

<p>Ouch...</p>

<p>As a Suns fan, even bringing that up STINGS.</p>

14

<p>PR talks about imaginary numbers, complex numbers, and complex planes in the miscellaneous section.</p>

15

<p>That isn't exactly true. In college boards math II book(real test), i saw a question about imaginary numbers. That said, you only really need to understand graphing in imaginary coordinates, and maybe some simple cis problems(though i havn't seen any cis problems on it).</p>

16

<p>im thinking its like</p>

<p>what is |6+5i|
the answer would be |sqrt(6^2+5^2)|= absolute value of sqrt(61)
thats the only problems that come to mind besides whats i^51</p>

<p>if you had the ti 89 titanium, you could answer it in 2 seconds. :D</p>

17

<p>^ I saw something similar on the CB test.</p>

<p>Also, there was one question with a point graphed in the complex plane and it asked which other point had to be on the graph.</p>
