<p>Ugh I made 2 stupid mistakes plus probably 1 or 2 other careless mistakes. Is an 800 still possible??</p>

182

<p>@etshine obcourse, typically u can omit 7 and get a 800.</p>

<p>does anybody remember the graph one?
it was like how many times does it cross the x-axis…</p>

183

<p>yea it was 2 I believe (if you set y=0 you something like x^2-2x=0, which has 2 solutions)</p>

184

<p>anyone remember the answer to the one which gave you side lengths of like 4 and 5 and then gave an angle of 50 degrees, then asked what the are of the triangle was, answers were between 4 and11???/</p>

185

<p>The answer to that was .5ABsinc, so 7.66.</p>

<p>I thought this test was relatively easy except I can’t believe I made a stupid mistake on the prism problem where you had to give the volume in terms of m.</p>

<p>Also, the determinant was 0, right? 6-6?</p>

186

<p>@ huehue yea that’s correct.
Also do you rmbr the answer to the prism problem/the answer to it? I realized i may have made a careless mistake on that one</p>

187

<p>does anyone remember the question for the answer -sinx and absolute value of sinx? </p>

<p>and also does anyone remember the equation/question for the february and august one? was one of the choices january and august?</p>

188

<p>yeah. i mightve said january and august</p>

189

<p>@polergunt
I remember putting 11 for that one? But then again I’m not quite sure. Anyone else know?</p>

190

<p>^ I think it was 11 point something though?</p>

191

<p>Did you guys remember the lim questions. Where you plug in -1? I think I got 0/0… Or am I mistaking it with a question I did in my prep book. Lol. Someone confirm lol</p>

192

<p>No smarty, there weren’t any lim questions on this test i think…</p>

193

<p>I’m pretty sure it’s February and August (1.2 and 7.7 or something; 0-1 was january). Also, [this</a> was the sin graph segment question](<a href=“http://i.imgur.com/H8LAaSK.png]this”>http://i.imgur.com/H8LAaSK.png).</p>

194

<p>@jguskadoo a lot of other people said the answer was February and august in previous comments. I graphed it on my calculator though and i’m pretty sure one of the months was january</p>

195

<p>because x was like 1-1.9 in the peaks. unless x=1 is february</p>

196

<p>I thought it was February and July?
I got 7.8 something for the second maximum on my graph, so i thought since it didn’t reach 8 yet it was still in July.</p>

197

<p>0-1 January
1-2 February
2-3 March
3-4 April
4-5 May
5-6 June
6-7 July
7-8 August</p>

198

<p>@sidedishes was one of the answer choices -sin(x) only?</p>

199

<p>I put -sin(x) and |sin(x)| but not cos(x)… is it this question? <a href=“http://i.imgur.com/H8LAaSK.png[/url]”>http://i.imgur.com/H8LAaSK.png&lt;/a&gt;&lt;/p&gt;

200

<p>yeah. i dont remember what i put but i think i may have said -sin(x) only. which is wrong.</p>
