My students are also super curious about this. I'm...really not sure on this one. On some level, I think you will lose a point because it actually equals it exactly so saying it is less than the given value is not true. On the other hand there are only 9 points to be distributed and the policy of not requiring simplifications makes problems like this a little harder to predict the scoring for.
Dont worry i did the same mistake but if you realize that in any error bound approximation you must have the less than or equal to. We are not sure that the omitted term will be always less than 0.45 since this can vary if the series was centered at 1 or 2 or 3 or etc. It happened to be lucky that the bound was exactly 0.45 centered at 0.
NineCubed I just always thought it was less than lol maybe I should have calculated it out..I remember putting it into my calculator after the test and I was like oh shit lol
For this FRQ, I got almost everything right (left part D blank), but I got the wrong value for f(0). How many points will I lose as a result? Everything else was correct.
I'm thinking you'll lose 1 point for that, but that's just a guess since I'm not a grader and no one knows how they'll score these things yet. It shouldn't cost you any other points though, I would think.
@@turksvids However, in part C, it is required that you use the Taylor polynomial derived in part A. Will I lose additional points for this since I got the Taylor polynomial in part A incorrect?
You shouldn't. If you have to carry an answer forward it's been past practice to allow earning points on later questions based on previous wrong answers.
hello- on the h(1) approximation i only plugged 1 into the first three terms- getting 2.5 as an answer. is this incorrect? it never specified to use all four terms, though that might have been implied. please let me know. thanks
The problem said to use your answer from part a, so I think you'll be losing a point on that. (Or maybe on part a you only using three terms instead of writing a third degree polynomial? Either way you'll lose one point for one of those mistakes but not one point on each of them.) I don't know how part d would get scored in that case because I'm pretty sure the error you get using only three terms in your polynomial will not be less than or equal to 0.45, but I didn't do the math.
This man is a legend, appreciate you work my man. Help BC kids sleep at night with these solutions :D
I found your videos while cramming for my exam tomorrow. Oh how I wish I found your channel earlier. These videos are super helpful
Doh! I wish you'd found it sooner, too! Good luck on the exam! Please help spread the word so that others don't have the same experience!
Looking back at this and realizing I made more mistakes than I thought---SMH
Elek Miller bet u didn't make as big of a mistake as using degrees instead of radians :/
I got a 5 on my calc bc test this year studying with your videos! Thank you so much for making them!
Awesome! Congrats on the 5. Thanks for watching!
Hey! Would I get the last question wrong for saying that it is ONLY LESS THAN and not less than or equal to 0.45? Thanks.

Yea I made the exact same mistake because I was super low on time and wasn't able to calculate 54/120 in my head
