Could someone explain to me how Lagrange Errors Bounds work



Honestly, if you’re so unlucky that you get a FRQ sub-part on Lagrange, just skip it. It’s going to be worth 2 points, max. Memorize the formula and write it down if you do get that question and see what inspiration comes to you during the test. Don’t worry about it.



how well do we need to know our Trig Identities



Know the ones you know and probably have sum, difference, and power-reducing in the back of your mind. You won’t need the others you listed.



And how complicated can partial fractions get? Will there be functions with degree > 2 on the bottom?



No. At least, not that I’ve ever seen.



Will you ever be asked to apply the Squeeze Theorem in an explanation?



Not that I’ve seen, but who knows what’s going to be on the test this year? Just know it; it’s not too complicated.



Also other than the e^x, 1/(1-x), sinx and cosx, are there any other Maclaurin series that I should memorize for the test?



Umm, I don’t think so; anything else should be easy to generate. Do know FOR SURE how to take the series for something like e^x and turn it into the series for e^2x. It’ll save you a lot of time and trouble if you can use the series you know in your head (e^x) to get to e^2x than to have to take 3 or 4 derivatives and blah blah blah.



And when they ask for areas of polar figures do they use phrases like " one petal of the rose curve" or “inner and outer loops of the limacon” or do they usually give you the limits of integration?



I have never seen a polar problem where they give you the limits of integration.
