<p>It does. The height is determined by f(x)=ln (x^2) The right bounds yield a significantly greater area.</p>
<p>Yes but in terms of accuracy they're both inaccurate...<em>shrugs</em> So then, for this question which one would have been the better choice? right or left?</p>
<p>the answer to the reimann sum question was 21. The way the rectangles were shaped, it was obviously a right hand approximation, meaning you would take the functional values of the right most side of the square.</p>
<p>Okay, cause I couldn't remember now the graph's shape. Guess I got that wrong,then. Or does anyone know if in this case both would have yielded approximately the same answer?</p>
<p>you could have always just used your calculator to integrate to see what the answer should be about, and then see if the rectangles were larger/smaller and changed the area accordingly</p>
<p>"The right bounds yield a significantly greater area."</p>
<p>Hummm Okay then. =P</p>
<p>wat did u guys get for the one where it said all the logs are = EXCEPT and listed a few answers (i put somethin like log2 5 or something like that)</p>
<p>I put B, but i can't remember what the exact answer was. B was the only one that didn't equal to 2.</p>
<p>Yeah, it was log2 5. :)</p>
<p>How about the one asking for the possible inverse. I got the one that was facing the 3rd quadrant. I think it was letter C. Anyone remember/know that one?</p>
<p>it was the one that was upside down and shifted up 10 units</p>
<p>I think that one was B? It was the second choice on the first row.</p>
<p>i thought the second first row was C...maybe not but i think thats what i put</p>
<p>I was surprised not to find a single Polar/Parametric problem. I over-studied them cause I didn't feel prepared for those questions :P</p>
<p>Yeah, I was reviewing last night it my book said that polar problems rarely came up. I didn't even bother to study them.</p>
<p>Ah, both polar and parametric were on there when I took it on October. It was scary.</p>
<p>Polar and parametric were there in November too, actually. Anyway, can we get some estimates here? What d'you guys think you got?</p>
<p>Skipped: 5
Think I got wrong: 9</p>
<p>Raw: 33.75 = around 700</p>
<p>I didn't skip any (I always think that if it's possible to get that 1 point at the risk of .25, do it).
But I think I got maybe 10 wrong (4 from this thread, 5 or 6 I can't remember probably).
Raw: 38 = 750. If I get less wrong (I hope), I might break 770 or 780.</p>
<p>minor correction: the answer to that log exception problem is log2 4, not log 2 5. Don't worry though. I think that's what you guys put because none of the other answers had a log base of 2.</p>
