<p>what was the answer to the matrices one? (last question) 5 x 2 or 5 x 4?</p>
<p>@Recline that’s exactly how I solved it. :P</p>
<p>I think some of my logic for doing that came from just learning trig substitution for integrals in my Calc class.</p>
<p>@diddly123 about a 730, depending on the curve</p>
<p>thanks! but wait, is the period not bπ?..</p>
<p>No way the curve can be 45<= for 800, right? Sitting at a 44 (worst case scenario, assuming everything I’m not sure of is wrong) atm, debating on canceling</p>
<p>can someone please answer my question about the period of the tan graph with the b?!?!?!?!?</p>
<p>Any consensus about the ambiguity of the real zeroes question?</p>
<p>For the largest angle of the triangle:</p>
<p>The largest side was 4 and the two other sides were the square root of 13, or 3.6. How could the largest angle be much larger than 60 if the sides are approximately the same?</p>
<p>Edit: Wow… it was 6, not 4… DAMMIT!!!</p>
<p>i got the largest side was 6</p>
<p>Largest side is not 4, it’s 6. x coordinates were 3 and -3.</p>
<p>I know, I know. That’s what I get for only getting three hours of sleep. xD</p>
<p>please please please please what is the answer to the period with the tan graph?? :(</p>
<p>Does anyone remember if the ice cube question just required u to plug the answer in to get 25?</p>
<p>^diddly123 the answer was pi over b</p>
<p>how though? i got bpi</p>
<p>i found the two asymptotes and just took the difference</p>
<p>^the period of a tangent graph is pi, if you graph it one cycle goes between -pi/2 and pi/2, and since you had a tan(bx), you have pi/b</p>
<p>can someone clarify what question this was? Can’t seem to recall it
49. Possible values of x and y. It can be +,-,0</p>
<p>Does anybody remember the actual question about which point stays the same after being reflected over a certain line? What was the equation for that line? The answer was (8,17)…</p>
<p>Apologies for bringing up the sphere intersection question again, but is everyone positive that the question asked about the surfaces, and not “volumes” of the spheres?</p>
<p>If not, one sphere could sit inside a larger sphere and their intersection would be a sphere the same size as the smaller.</p>
<p>agreed, i got pi/b</p>
