<p>Should I memorize them?</p>
<p>You should memorize everything. Its not like you have anything
better to do with your time.</p>
<p>Don’t memorize anything. When I took MathII, I finished the test in 20 minutes. You have time to derive anything you need.</p>
<p>TheBoyDave - how would you derive half angle formulas?</p>
<p>You really don’t need to memorize /anything/ for the math2 test. like the other dude said, you’ll have plenty of time to derive anything if you really need to… though knowing some of the conic sections stuff by heart would save some time. </p>
<p>(also, for half angle formulas, [4</a>. Half Angle Formulas](<a href=“http://www.intmath.com/analytic-trigonometry/4-half-angle-formulas.php]4”>4. Half Angle Formulas))</p>
<p>Very nice site Urc</p>
<p>Just program them into your calculator it’s so much easier.</p>
<p>Be familiar with them and program them into your calculator. That’s the best way imo 
Unless you’re bad at recognizing when to use something unless you have memorized it…</p>
<p>They do appear on Math Level 2.</p>
<p>Definitely memorize any/all formulas. I didn’t have any questions that required those formulas on my test, but since every testing date is different, it’s better to be safe than sorry. Besides, you have the entire summer to remember a few formulas.</p>
<p>yeah, deriving is good and all for a lot of stuff, except to derive the half angle formula, according to the website, you have to use the double angle formula, whose derivation requires the additive angle formula, the derivation of which is not entirely obvious. </p>
<p>But yeah you should be able to derive most of the formulas you encounter by yourself, and this holds true for almost any math test you will take.</p>
<p>It’s not a good idea to try and derive formulas while you’re taking a timed test though :)</p>
<p>^I assume most of the people who want to/end up deriving formulas on tests are not the ones who have to worry about time issues.</p>
<p>I would recommend memorizing them. </p>
<p>I didn’t really start studying until a week before the test, so I didn’t bother to memorize double angle formulas because I thought they probably wouldn’t show up. So of course, they did. I had to derive it, which wasted a good amount of time. I finished the test, but I didn’t have time to check over my work. No harm done in the end, but still… safer to memorize and save a bit of time.</p>
<p>Lol I just put them in my calculator.</p>
<p>^Lol, that works too</p>
<p>When I took the test I thought that we weren’t supposed to use any programs, so I didn’t bother to put anything in my calculator… but I guess that isn’t true, then? Are we allowed to use programs for SAT I math?</p>
<p>Well they don’t check your calculator, so I guess yes :D</p>
