<p>On the Math tests, you're permitted to use a programmable calculator. Do they check if you saved a list of useful equations in it, such as area and volumes of solids and trigonometric identities?</p>
<p>Would it be value to put these things in your calculator so that you don't need to memorize all the trig. identities and so on?</p>
<p>they don’t check your calculator. and i have never encountered a math problem that required the recalling of trig identities.</p>
<p>I was under the impression that a large part of Math II subject test was on trigonometry and asked to simply expressions using the trig identities?</p>
<p>I am also curious to hear from someone who has experience with the Math Level II subject test. Did you need to recall the trig identities, and how often?</p>
<p>One of my friends has said yes but only on one question, the other no.</p>
<p>I had two questions on trig. That was last May or June, I don’t remember.</p>
<p>Anyway, one time I was taking the regular SAT and the proctor went around the room (so time consuming…) and completely wiped out everyones info storage. COMPLETELY. Meaning I lost my chem notes, stats program… Aughhh…</p>
<p>My subject test proctor could have cared less if we programmed stuff in though.</p>
<p>And the Barrons book gives you programs like quadratic formula, distance forumla so you don’t have to do the math for the subject test. So I am assuming for subject tests that programming equations into the calculator is fine.</p>
<p>digging up an old thread… but any new input on this? i was wondering if there was anything i should put in my calculator beforehand</p>
<p>You don’t need it. I used a TI-84 graphing calculator but I never had to use anything other than the X,+,-,/,sin(,cos(,tan(,and ^ which a scientific calculator can easily do.
The equations are really simple and typing them in could actually waste time.</p>
<p>Here are a couple that would save a lot of time:</p>
<p>Area of a regular polygon given side length:</p>
<p>Disp “Change mode to degrees, N = number of sides”
Prompt N
360/(2N) -> A
Disp “S = side length”
Prompt S
(S/2)/tan(A) -> H
.5(SH) -> B
BN -> Z
Disp “Area is”
Disp Z
Stop</p>
<p>Finding average rate given 2 rates:</p>
<p>Disp “A and B are 2 given rates”
Prompt A
Prompt B
2/((1/A)+(1/B)) -> R
Disp “Average rate is”
Disp R
Stop</p>
<p>1 version of Law of cosines (find an angle if 3 sides of any triangle are known)</p>
<p>Disp “A, B, and C are side lengths, C is side with desired angle, change mode to degrees”
Prompt A
Prompt B
Prompt C
cos^-1 ((C^2 - A^2 - B^2)/((-2)(A)(B)) -> E
Disp “Angle C is”
Disp E
Stop</p>
<p>Heron’s formula (finding area of any triangle given length of sides)</p>
<p>Disp “A, B, and C are side lengths”
Prompt A
Prompt B
Prompt C
(A+B+C)/2 -> S
sqroot(S(S-A)(S-B)(S-C)) -> D
Disp “Area is”
Disp D
Stop</p>
<p>Alternate form of Heron’s formula (finding area of any triangle given 3 coordinates)</p>
<p>Disp “(A,B), (C,D), and (E,F) are coordinates”
Prompt A,B,C,D,E,F
sqroot((A-C)^2 + (B-D)^2) -> X
sqroot((C-E)^2 + (D-F)^2) -> Y
sqroot((E-A)^2 + (F-B)^2) -> Z
(X+Y+Z)/2 -> S
sqroot((S)(S-X)(S-Y)(S-Z)) -> G
Disp “Area is”
Disp G
Stop </p>
<p>Not sure how much these will really help, but if you’re bored, might as well put them in. Who knows. They could end up helping you on the actual test.</p>
<p>Its also a really really really REALLY REALLY good idea to program all those trig identities and such into your calculator. It could REALLY help you</p>
<p>I’ve never seen a trig identity pop up before on a test though o.o</p>
<p>It’s explicitly stated that you are not required to clear your calculator before the test, so you should definitely fill it up with whatever you need before you take it!</p>
<p>Yep probably gonna include the trig identities, and maybe the interest growth/decay formulas</p>
<p>i also heard that series and sequences will be on the test, so having the nth term models might be beneficial</p>
<p>Going to include Heron’s formulas because finding the area given only side lengths/coordinates (ESPECIALLY coordinates) just takes so long.</p>
<p>I don’t know how necessary it is. I suppose it could help on a few questions, but I didn’t need it at all for mine.</p>
