<p>That you are most likely to not have already memorized.</p>
<p>Surface area of a sphere:
4 * pi * r squared</p>
<p>Volume of a sphere:
4/3 * pi * r cubed</p>
<p>The diagonal (3 dimensions) of a cube of sides 1 is:
square root of three</p>
<p>Interior angles of a polygon:
180(n-2)</p>
<p>That’s cheating. You’re given formulas at the beginning of each math section. If you need a formula that’s not there, then you need to memorize it.</p>
<p>Nope. Not stated anywhere in the rules that you can’t input formulas into your calculator. In fact, proctors aren’t even allowed to clear your memory:</p>
<p>
</p>
<p>The rules state you aren’t allowed to bring outside help material to the exam. Calculators don’t come stored with those data. Therefore it’s cheating.</p>
<p>I don’t get the point. These formulas aren’t even necessary for the SAT; all of the formulas that you need are given to you, or can be figured out. If you really wanted to memorize these for some reason, you could do so really quickly–like, in one minute. It’s not like they’re difficult formulas. </p>
<p>It seems like more work to put them in your calculator, regardless of whether it’s against the rules or not.</p>
<p>Not only do I disagree that calculator data is outside help, but as renoverchat explained, it’s not much help at all. The SAT designers don’t care what you put in because it will barely help you. </p>
<p>But addressing renoverchat, I couldn’t derive 180(n-2) on my own. And by making this thread I’m at least alerting people to take note of some formulas they might not have considered or seen before.</p>
<p>It’s not calculator data. It’s outside data put into a calculator.</p>
<p>I suggest you read their calculator policy and do some Googling to look at others who have asked if it’s allowed.</p>
<p>Those are pretty easy to remember. Why would you have trouble remembering that the sum of the interior angles of an n-gon is 180(n-2)? Just n-2 non-overlapping triangles…</p>
<p>I really don’t need to seeing as though I’m a Harvard student, but good luck to you.</p>
<p>Whoa watch out guys, we got a Harvard student!</p>
<p>Being a Harvard student does not grant you inherent knowledge of the SAT calculator policy, which you seem intent on arguing about despite claiming it doesn’t matter to you.</p>
<p>BassGuitar, I completely agree with you, as I read the calculator policy all the way through and my face lit up when I heard that I didn’t have to clear memory. I stored three equations in it for the Math 2 SAT II, never used a single one. Despite that, it’s still nice to have.</p>
