<p>what would I get if I had at least 28 MC, prolly 30.<br>
And about 22-24 on FRQ</p>
<p>Is it 30*1.2 + 22 </p>
<p>but then what is the cutoff for a four?</p>
<p>like for 2003 it was 53, i think. Do u think for this year it will be a bit lower since it was considerably harder i.e 50 for a four?</p>
<p>I got smoked on it. On the first FR, I changed the equation with respect to y, since I figured that was the only way to do it, and it ended up not allowing me to evaluate in my cal since the graph went to infinity. How did you guys do that? What integral did you use? I was thinking of keeping it with respect to why, but it the representative rectangles can't be stacked up to infinity.</p>
<p>Also, I have never had to work with graphs that go to infinity and revolving about an axis like on that AP. I was thinking about it... if the graph goes to infinity, isn't the area under it infinity?</p>
<p>I understand how to do taylor series to an extent. THe major things they ask is to write out terms and the general term. Then from that info to find out the interval of convergence or Lagrange error bound. That’s where I am very very confused.
to find IOC simply use ratio test, right? Then where do you go from there as in to prove convergence. I usually get the problem to |x| < 1 then I have no idea once I find the x values, how to plug them back in and find which converges. Also, for Lagrange error bound… you need to find the maximum (usually the next term) but once you set it up as | f(x) - P(x)| < f^n+1 (x-C) / (n+1)! < <em>say 1/1000</em> what exactly are you solving for? And how do you find the coefficient of a certain term?</p>
<p>If someone could elaborate on the Lagrange error bound, that’d be great. I still don’t really understand it. Eff series.</p>
