<p>In this image, the red shaded part is the limacon sector and the blue shaded part is the circle sector. This should help you visualize it.</p>

<p>Fantastic explanation, sparklesheen. Though I don’t think I would be able to think of that during the test.</p>
<p>yeah sparklesheen, please explain every other topic on this exam…if you do, i will get a 5 hahahah</p>
<p>THANK YOU SO MUCH. I’ve never even heard of a limacon, but I think I get it now. thank you!!!</p>
<p>I’m glad I could help! A limacon is just that funky heart-shape haha. Knowing that doesn’t make any difference. :)</p>
<p>Damn…the two things I need to study most ATM are polar and Taylor/Maclaurin. Cram cram cram!</p>
<p>If there is a graphing problem, it shouldn’t be too hard. Just keep a mental picture of the 4 different concaves and their first/second derivatives.</p>
<p>This cram sheet is super helpful and has all the formulas, etc.:</p>

<p>Me too, about the polar and Taylor/Maclaurin stuff. I get the idea of Mauclaurin series but for some reason I always get them wrong. Any general tips?</p>
<p>One kind of helpful thing my teacher said last semester was, if you have absolutely no idea how to approach the problem, at least write down the integral sign/limits of integration for easy points</p>
<p>Thirding the Polar and Taylor/MacLaurin cramming. Also, thanks Sparklesheen for the cram sheet! Finding it super useful so far.</p>
<p>blorgit - You’re going to Penn! Yay! Sorry, completely random haha.</p>
<p>Ok gonna go get some sleep and hope for the best tomorrow… any last minute tips from anyone???</p>
<p>dont fail? :p</p>
<p>Thank you, much appreciated tip xD</p>
