<p>The slope of the spiral pi/4 is?</p>
<p>r = pi/4</p>
<p>It’s a polar curve; an archimedes spiral. It ususally asks for the slope at a point though; not the general equation for the slope.</p>
<p>Does it appear on calc bc exam in the past?</p>
<p>Yes. Polar is a significant part (at least 10-15%) of the AP Exam.</p>
<p>^really? I thought it wasnt tested that heavily at all. I have seen like 1 or 2 in the multiple choice and like 1 frq regarding polar. I think parametrics are tested more, imo.</p>
<p>Polar is definitely fair game on the test for both MC’s, probably more on Section B, and there can definitely be a Free Response on Polar too but it’s more likely that they will give a parametric question instead and there is almost always an infinite series question on there.</p>
<p>yeah, t-san is right. polar is a major part of bc. in fact, it’s one of the topics that separates bc from ab-- of course you have to ace the ab part first to get the 5 in bc.</p>
<p>but polar and series are important, so i’d learn those quickly.</p>
