<p>It was (-8/3, 0). Remember it had to be on x-axis. You didn’t even need the pythagorean theorem. You could just eliminate illogical choices.</p>
<p>itsakanksha did you get both. my memory is really failing me.</p>
<p>No, I remember choosing (-8/3, 0)
I just substituted the values or something.</p>
<p>@SAT There were two. My graphing calculator has a polynomial solver. The two real roots were -1.068, and -7.402. </p>
<p>And there were two imaginary roots as well. 0.4854+0.2836i and 0.4854-0.2836i.</p>
<p>yeah i chose -8/3, 0 just by making an x-axis and seeing which made the most sense. didnt have to use any math.</p>
<p>it seems we have covered most, if not all,of the noteworthy stuff.</p>
<p>There was a question with um, tan(pi x) or something. Does anyone remember that?</p>
<p>Thanks, I got that wrong then. I was just looking at the graph, which was misleading. I guess 89 is an advantage. </p>
<p>Did anyone get 5 for the arithmetic sequence 1st term?</p>
<p>I dont remember the exact answer. was around 1.
tan^2 x = number </p>
<p>what is cot x? is that it.</p>
<p>itsakanksha, I got 5.</p>
<p>@HBound. I got something like 1.something.</p>
<p>I put 5 as well</p>
<p>^ No, no, not that one. It was big function along with (tan pi x). I think we were supposed to find an asymptote or something? I’m not quite sure.</p>
<p>The one you are talking about, I got the answer as 1.something as well. I think it was 1.49 or something.</p>
<p>Also, there was this function where we had to find how the function increases and I chose “infinitely without bound”. Was that an answer for one of the questions?</p>
<p>did anyone get .64 for sin squared x?</p>
<p>@HBOUND - Yup :)</p>
<p>yeah, it was infinite without bound. was tan pi x the amplitude question? taking physics afterwards, i do not remember all the questions.</p>
<p>I thought the graph had 3 roots. The graph went negative and then positive and had a double root in the x and went up.</p>
<p>Oh yayy :)</p>
<p>Ahh, I can’t remember :P</p>
<p>Same, haha ^^</p>
<p>@sgtgutter - which one are you talking about?</p>
<p>I think it was what was the limit of some function? It was toward the start of the test. It had a square term in the denominator. </p>
<p>Also, another one was 2^x was the function that is greater than the others as it increases.</p>
<p>Was there a question with r and s and s is less than 10. I put s = 9</p>
<p>It was .64. That was a trig identity.</p>
<p>yeah oh there was that question which one will surpass the others. i think i put 2^x because it was exponential.</p>
