<p>thanks physicsboy32 :D</p>
<p>wait wasn’t it sin x > cos x…if not, fmlfmlfml.</p>
<p>@ch0pstick that’s the answer - you have an absolute value, meaning that everything becomes positive. Then you have the (-) turning everything negative => below the x-axis.</p>
<p>Chopstick it was less than or equal to</p>
<p>CyberNareN12 i’m pretty sure that it was sin less than or equal to cos</p>
<p>lol it was sinx < cosx</p>
<p>lets get the rest of the answers but I’m already ****ed off at my stupidity. ._.</p>
<p>I remember one of the last ones, u had to use law of cosines</p>
<p>and the circle one had like an angle theta which equals 120 degree, and u found the tangent of it i think? I’m worried i was accidentally in radian mode for that.</p>
<p>there was one where a line passed through center and a point forming a 3,4,5, triangle. the cos of that was like 3/5 or 4/5 cant remember</p>
<p>there was one with a proportion and 75% cant remember that one exactly but you set an equation equal to 75/100 and cross multiply</p>
<p>There was one for which you just needed to know that sin(2A)=2sinAcosA</p>
<p>physicsboy32
The answer to the circle was was -1.7 (=-root3)</p>
<p>yeah one of em you just did tan120 = -1.73</p>
<p>what a stupid way to lose a point for that sinx<cosx :(</p>
<p>the law of cosine one was the sides of a triangle are 5 6 7 what is the angle for the 7 one i think…</p>
<p>sin(2A)=2sinAcosA</p>
<p>or u cud just use the calc ;D</p>

<p>Spookie123
I think the one you’re referring to is
If sin (2x) = a, what is 2<em>sin x?
I got (E) a</em>sec x</p>
<p>7 blanks and 2 mistakes :(</p>
<p>In your opinion can I get =>700 with 7 blanks and 6/7 mistakes?</p>

<p>for the height/width chart question, were we supposed to convert from inches to centimeters…?
I thought we were at first, but since it’s the RATIO wouldn’t that mean that it would apply to all units of measurement the same way?</p>
<ol>
<li>i agree</li>
<li>2 times</li>
<li>I got 2</li>
<li>I got 4</li>
<li>the answer is one bottom of page 2 i think</li>
<li>is 19. it is the greatest int function where n = 300000</li>
</ol>
<p>yea u dont have to convert between anything</p>
<p>for #23, what I remember is that I had 0 for x twice (with different y’s) so it wasn’t a function. II was the same table as I, but with the x’s and y’s switched, so it had 0 for y twice, but that’s not a problem. III had 1/2 as all the y’s, so it was a horizontal line, which is fine, too because it passes the vertical line test. So the answer should be II and III only, as people have been saying</p>
<p>they didnt test a lot of the concepts i studied for… ._.</p>
<p>no permutations, combinations, geometric seq, vectors, logic statements</p>
<h1>18 asked for the area of the region 6 units from a given plane and not more than 12</h1>
<p>units from a given point on that plane, so it was a circle with radius root(12^2-6^2) and therefore the area was 108*pi or (C) 339</p>
