Review Session

There will be a review session tomorrow afternoon 4:00-5:15ish PM in Wexler 206

where and when is the final exam?

Prof. Taylor,

I just wanted to make sure when the final exam was. Your syllabus says it is May 2nd, at 7:10pm, but the ASU schedule says it will take place May 3rd, at 9:50am. I just don't want to end up showing up to the wrong exam time and day. 

Thanks in advance,

*****************

Glad you asked.  I have had otherwise smart people miss the final exam on this point, which was disheartening for them. You are looking at the wrong part of the ASU schedule. You need to look at the part that has the common finals, all of the mat267 sections are taking the exam at the same time. The exam will be exactly when and where the syllabus says it is. 

class/review session

do we have class tomorrow?

*******************
no more classes. I will be at my office hour tomorrow and I will arrange a review session, probably Tuesday afternoon.

exam/practice problem 1

Hi Dr. Taylor, In this E-mail I've attached pictures of worked problems from exams 1 through 3 that I did not get 100% correct. I've additionally included one or two questions from the practice final that I am not sure if I did correctly. Any feedback would be greatly appreciated. 

Thanks,

this is good, and nice use of white board.  I'll be getting to the rest of these bit by bit today.  A thought for you and your classmates: these will display on the blog better if you write them so that they can be photographed in portrait rather than landscape mode.  As it is, to read this I suggest you right click (control click for mac users) and download.

13.6 confusion

Hello Professor Taylor,

In your 9:45 lecture this past Friday I thought you mentioned you would extend the due date of WebWorK 13.6 from Friday to Sunday at the popular request of the class. I was struggling to meet deadlines for multiple courses last night, so after confirming what I believe I heard in class with another student, I opted not to prioritize the remainder of the 13.6 assignment. As of today the assignment is closed, and is labeled as being due Friday at midnight. I truly hope my classmate and I did not misinterpret your comment in class, and consequently lose our opportunity to finish the assignment. Please clarify your point of view on this situation and inform me of what the outcome will be.

Hello Professor,

This is *********  from your calc 3 class. I was working on Webwork 13.6. and the due date is tonight April 28. This class morning you changed the date to Sunday. Thank you. 

Sincerely,

***************

Well, maybe. My recollection though is that I left 13.6 alone and changed 13.7 to allow more time.  In any case, since nothing gets done until the last minute, I've changed 13.6 to be due Sunday night as well.

solutions to exams

Hi Dr Taylor,

Could you post the solutions for exams 1-3 for MAT 267 on the blog.

Thanks,

************************

No, because the answers won't help you if you don't do the problems. If you work the problems *again* and send photos of your answer written out on fresh paper, I will discuss your answer and give hints here on the blog.

Practice Final Exam

Practice Final (last year's final)

Office politics and numerical answers

So yah, it's true, this is an engineering class and you get to use your calculator to get the answer on the exam unless I the problem commands exact answer only.

But picture this: you're working in an engineering group meeting roughing out a device design and your boss throws out a rough model and you whip out your cell phone calculator and compute that the net voltage/force/pressure differential answer is 10^-15.  Should you report this number to the group? Or should you report that the number is zero?  Which answer would get you more respect from your cohort?  Under what conditions?  What if the true answer for the model is fairly obviously  exactly zero, even though the model itself is an inexact approximation of the device?

and 13.4 glitch

Hi Dr. Taylor,

WW 13.4 was closed early today at 11:59 am instead of pm. Was this a mistake or was it due at this time?

Thank you,

********

Hey,

<snip>

Was the webwork section 13.4 due sometime earlier than tonight? (Friday, 4/21 at 11:59pm)

I thought all homework was only ever due on Friday nights and even double checked earlier this week

but I could be wrong. Was it due Wednesday?

Thanks

****************

My bad.  Fixed. Now due Saturday night at 11:59PM

exponentials

there are an amazing number of people who think that e^0=0 and/or cos(0)=0

It's that grade your instructor time of year
