Thank you!!! I have had Ap Cal for my pass year and never understood what I was doing or how to do it (no matter how many videos I watch) Tommorrow I have my AP test and I now get it ! Thank you so much!
hi! How did you know that it was one trillionth rounding error? Also, you have a typo at 15:09, you put an extra and. Also, when you said limit, did you mean an actual limit or just a bound? Thanks
If you work out the problem without a calculator, which I did using the quotient rule, you will get an answer of -1/25, which is -0.04. So what the calculator got for an answer, -0.0400000016, is 1.6 times 10^-9, or 1.6 trillionths less than the real answer, and thus a calculator idiosyncracy. As for the typo, I copied the problem from College Board material, but looking at it closely, while maybe awkwardly worded, I can make a case that each of those 3 ands serve a purpose. As for your final question, I said limits as an abreviation of "limits of integration", which is synonomous with bounds of integration. You have a keen eye for detail. I doubt I have had any viewer look as closely at the details of any of my videos so far. BTW, if you do look at more of my videos, which I hope you will do, you will find a lot of mistakes, some of which I notice as serious enough to redo a video. But some errors I just leave in if noticed when I think they're too minor to cause harm. Thanks for viewing and especially for commenting. A student of calculus could learn a lot just from looking at your questions.
