<p>If I look above the window, I'm not going to find anything...b/c that equation has an asymptote at x=0 and y=0.</p>
<p>Maybe I'm not seeing it correctly, but prove me wrong if you can. I didn't know how to respond to this question...so I just used +-3, but setting the equation = to each other..and then got like -37 something for the area, which didn't make too much sense...but oh well...</p>
<p>no it doesnt. It has no asymptote at all.
Listen im 100% sure.
I even checked it afterwards with an 89 and i got it right.
x^2+1 is the denomintaor (not x^2)</p>
<ol>
<li>Screwed the whole thing up by shading the wrong region...</li>
<li>
a. I integrated the formula from zero to seven to find accumulated change, but I think I messed it up because I forgot about the g stuff.
b. I didn't know what to do for this one. I just bsd the answer
c. I didn't know either...I just said at seven...sigh</li>
<li> the f(g(x)) didn't work for me...I just said put hat the intermediate value theorem proves the point's existence, and then I said that the mean value theorem for h'(-5). I tried to work it out mathematically, but I couldn't do it...</li>
<li>(e^-t)sin(t) I set the derivative equal to zero and found a minimum...I forgot what point I said...anyone?
b. WTH?</li>
<li>a. I said f(x) + f'(x)(delta x) and got like 30.4
b. implicit differentiation
c. I found (b-a/n) and then I quit because I was too frustrated, but I think I now know what I should have done
d. I said less because it is an under approximation</li>
<li>I did as much as I could. I couldn't solve c though, so I just set it up</li>
</ol>
<p>I'm sure none of you screwed up as bad as I did...
SIGH
Do you think I'll be ok if I did well on multiple choice? I was so nervous on FRQ</p>
<p>I am not sure why you are assuming y=0 in the first place, that seems like it came from nowhere. It is not an asymptote as it approaches 0, a simple substitution of 0 for X shows that y approaches 20 as x approaches 0.</p>
<p>George thats wrong. Look at this. You said you were looking for an asymptote when y = 0. THIS IS A HORIZONTAL LINE. Not vertical. What this means is that the HORIZONTAL asym. will go to 0. NOT vertical.</p>
<p>I thought 20/(1+x^2) didn't have a vertical asymptote because the denominator can never equal zero. It shouldn't have a horizontal asymptote because it is in the form of the p-series (1/n^2, which converges definitely when the exponent is greater than 1), right? I'm probably explaining it all incorrectly since math obviously isn't my forte, but I graphed the function a billion times and it definitely doesn't have any asymptotes.</p>
<p>i just went with my gut though...i thought something was fishy...i didn't set my window range correctly, but i went with my gut...and put down something</p>
<p>turns out it was right (except i threw in a negative there...probably did what gyros suggested)</p>
<p>Alright for 1c. isn't the region R the radius? How the hell is it the diameter? I thought that at first but then it didn't really give a hint to whether it was the diameter.</p>
<p>ok i got that 37 first..but then when i did it with my calc it got 12 n then somehow my calculations gave me 12..i think u guys are getting negatives because u putting one curve on top of the other which u shouldnt..cuz u put the curve closest to the top first when u integrate...</p>
<p>but yeahh except for that..in 2a. i got like 8000 something..i didnt..or dont think u have to subtract 5000..do u?</p>
