Turn in #11 is due Wednesday, Jan. 20, 2016!
This is for discussing assignments from WEEKS 4-6, including homework,
turn-in #11, MIDTERM EXAM REVIEW, in-class
work or lessons, or anything else related to the
class from these weeks. Please be sure to include your
name at the end of your post for credit. When answering a question, DO
NOT GIVE SOLUTIONS! Provide hints or explain a method that you used, but
do not give the final result. As always, RESPECT IS A MUST! Anyone
abusing this forum will be banned from future use (meaning, no extra
credit!!!).
So I'm kind of confused about what information is going to be on the test. I understand the general ideas but explicitly what information should we hold ourselves accountable for knowing? Like logistics and growth and decay, what kind of worksheets might be good ones to practice?
ReplyDeleteAs any professor will tell you next year, "if we spend our limited, valuable time in class covering something, then you are accountable for knowing it." Specifically, tomorrow's quiz is on solving differential equations, of which exponential growth and logistic growth are types, including Euler's approximations. See the review sheet we did in class on Friday 12/18.

ReplyDeleteDo we get to use calculators on the quiz?
ReplyDeleteYes, but only if it has a Pi key.
DeleteCan we use a calculator on 5b of the Turn In to find the limits of the integral?

I'm also stuck on #5b. Can it be done without a calculator?

I explained how to this in class on Thursday...you are not able to solve for the intersection algebraicly, and since a calculator is not allowed your only option is to label the point of intersection (a,b) and use this in your limit of integration.
DeleteI also had trouble on 5, but on the last part. I'm not sure if I'm completely forgetting how to take this integral or what. Does anyone have a clear idea of how to do it?
DeleteI set up the integral as the difference between the y values squared, but I don't know how to integrate it from there... hope this helps?
DeleteOkay if you expand the integral, from there you can integrate by parts!
DeleteBut it has to be integrated in terms of x because that's the axis it is perpendicular to. Right?
DeleteI've been trying #1 on the turn in and I keep getting a negative answer. This obviously doesn't make sense as the problem is area. Would it be appropriate to just take the absolute value in this case or does anyone have any suggestions about how to separate this integral? -Claire Westerlund
ReplyDeleteHow did you set up your integral? Nat and I found it to be positive; we split it up into two from 0 to 4 and then from 4 to 6
DeleteI realized my mistake. We need to set it up as the integrals to the x-axis from 0 to 4 and also from 4 to 6. -Claire Westerlund
DeleteAlso, I was wondering what some good options would be for a favorite mathematical superhero! -Claire Westerlund
ReplyDeleteMr. Awe(sum)!!
DeleteI mean, plenty of good superheroes are scientists. Look at Iron Man. He wouldn't be the badass tin can he is without math.

I have a few questions regarding the Midterm review sheet:
ReplyDeleteIs there an answer key and is it calculator or non-calculator?
-Sarah Mostofizadeh
The test itself has equal parts of calculator and non calculator so I'd assume the same would be true for the review. I also would check on the board in class tomorrow as Coach often has many answer keys clipped together. Hope that helps!
DeleteOn 2b, my infinite limit of an integral ended up with the limit as b approaches infinity of lnb which diverges... I think I might have set the integral up wrong; any ideas of how to do it correctly?
ReplyDeleteI'm not sure how to solve 5c completely by hand without a calculator! Any suggestions?
ReplyDeleteAfter I found the integrals and put in the bounds, I simplified my answer as much as I could and then I just left it. You could stop after putting in the bounds and it would still be correct. You don't have to simplify it all the way.
DeleteHow many questions is the free response section of the midterm?
