Practice quiz due date update

Antonio noticed that I had listed different due dates for the practice quiz on the OpenLab and in an email update. Sorry, my mistake! It was supposed to be due tonight (Monday) but since one of the updates listed the due date as tomorrow (Tuesday), I’ve changed the deadline in Webwork to tomorrow at 11:59pm.

If you need them, the practice quiz instructions are here.

Thursday update: test #2 and quizzes

I hope you are all still remaining safe and are in okay spirits. I know some of you are at home and bored and others are completely overwhelmed with new and sudden responsibilities. This is a difficult time to be a student! I hope you’re taking care of yourselves. I also hope your first online classes (which start today for some of you) go as well as possible! Our first online class is at 8am on Monday.

As usual, any plans we make now may have to change in the future. I really appreciate everyone’s patience and understanding. This will be an interesting experiment to say the least!

Test #2

Originally, Test #2 was scheduled for next Monday, March 23. The test has been postponed until the week of March 30. I’ll let you know more about how you will take your test soon. It will cover the same topics as originally planned on the old schedule.


We will continue having quizzes every Wednesday (unless there’s a test that week). Quizzes will be a combination of Webwork and written work: you will take the Webwork quiz and then email me a picture of your written work.

Academic integrity: Quizzes are “open book” but remember that your work must be your own. This means that you can use your own notes or the online textbook, but you may not work with your classmates or with anyone else, and you may not use any automated problem solvers or websites. You need to be prepared to defend your work orally in case I ask you to (I plan to do this randomly throughout the semester).

While I know most of you have been working hard, we have already had some instances of academic dishonesty in this class, which has been incredibly disappointing. It will obviously be harder for me to supervise you on these quizzes, so I must ask you to be fair to your classmates who are following the rules. Anyone found in violation of the rules will be reported to the college’s Academic Integrity Committee.

  • 1. Webwork component: Webwork has “quiz” features which are a little different from its homework features that you’re used to.
    • You will have a 24 hour window during which you can take your quiz, usually 8:10am Tuesday to 8:10am Wednesday.
    • Once you start the quiz, you will have exactly 10 minutes to complete it (unless you start late).  Webwork starts a timer and won’t let you submit your answers after 10 minutes, even if you log out and log back in again. If you start the quiz later than 8:00am, it will still end at 8:10am.
    • You will have only two attempts to enter the correct answer. So if you notice a typo, you’ll be able to fix it.
  • 2. Written component: The written component of the quiz is almost just like a usual in-class quiz. Your quiz question comes from Webwork, but your paper will look just like it would if you were handing in your quiz in person.
    • You will have 10 minutes from the time you finish your Webwork quiz to email me a photo or PDF of your written work. You may do your work on paper and send me a photo, but if you have a tablet you like to write on, you may send that file instead. If you take a photo, make sure it’s not too dark or blurry.
    • Include MAT 1575 and the quiz number in your email subject line. This is very important so that I can actually find your quiz later. My address is kpoirier@citytech.cuny.edu.
    • As usual there will be a total of 10 points with 1 for style and 3 for checking any antiderivatives by differentiating (where appropriate). If you complete only the Webwork component, you’ll receive a score of 1/10.
    • I’m not crazy about doing this part over email, so I am investigating alternatives for the future.

Quiz #5 and practice quiz:

  • Quiz #5 will be available on Tuesday morning and due by Wednesday morning at 8:10am. Emails with written work are due 10 minutes after you finish the Webwork component. (For example, if you finish the Webwork component at 6:45pm on Tuesday, the email with your written work must arrive by 6:55pm on Tuesday.)
  • A practice quiz is available now. Anyone who completes both components of the practice quiz will earn one participation point. You do not have to get anything correct, you just need to submit something for the Webwork component and send me an email with “MAT 1575 Practice quiz” in the subject line and some attachment that says “MAT 1575 Practice quiz” somewhere on it, even if it’s otherwise a blank piece of paper or a picture of your dog.


Webwork and Monday’s lesson

Here are my notes from and office hours: Note Mar 25, 2020

Here is the link to the video of the lecture: https://www.dropbox.com/s/eu8257lh2hbt2aj/Lecture%2020200325.mp4?dl=0

Here is the link to the video of office hours: https://www.dropbox.com/s/57r5zjw2e1xnq7v/Office%20Hours%2020200325.mp4?dl=0

I’m not sure whether I actually succeeded in recording the session today (sometimes it takes Webex some time to make the videos available). I’ll post the video link here if and when it’s available.

As of right now, in-person classes at CityTech are still scheduled for Monday. Edit: we will not hold in-person classes next week; classes will officially move online next Thursday. More details will be posted when they are available but you can see the Chancellor’s message here. For now, assume that you will be learning the following material yourself, at least initially. More details will posted as soon as they are available. Stay healthy!

For Monday’s lesson, we’ll finish Section 3.7 Improper Integration and cover Section 6.3 Taylor and Maclaurin Polynomials. I’ll include some material here in case we end up needing it. Quiz #5 next Wednesday will cover improper integrals of type 1. Continue reading


Webwork – Partial Fractions is due tomorrow (Tuesday); Improper integrals is due Sunday (we’ve cover about half of the material so far)

Quiz #4 (this Wednesday) will cover Section 3.4 of the text

Test #1 Solutions are due on the OpenLab by next Monday

Test #2 is Monday, March 23 (two weeks from today) on topics in yellow on the schedule

Stay tuned for your Test #2 Review assignment instructions

Updates & reminders

  • Integration by Parts due tomorrow
  • Trigonometric Integrals due Sunday
  • Trigonometric Substitution due March 1
Class Schedule
  • No class this Wednesday
  • No class next Monday
Quiz #2
  • Quiz #2 will be given in class at the beginning of class on Wednesday, February 19. It will cover material from Sessions 3, 4, and 5.
Trigonometric Substitution
  • After next Wednesday’s quiz, we’ll start the next topic: trigonometric substitution. You’ll want to make sure that you remember your trig identities and derivatives to prepare for this topic.
Test #1
  • Trigonometric substitution is the last topic that will appear on Test #1, which will be given in class on Monday, March 3. This might sound far away, but you’ll want to start preparing now. You won’t be told which integration technique to use, like you are in Webwork; you’ll have to decide on the best technique yourself (there may be more than one appropriate technique to choose for a given problem). Make sure to practice exercises where you are not told which technique to use. See the final exam review sheet and the end-of-chapter review exercises in the textbook.
Test #1 Review – OpenLab Assignment

Stay tuned for your next OpenLab assignment (spoiler: you’ll choose and solve one review question for Test #1 and post it to the OpenLab… details TBA).

Welcome, homework, and quiz

Welcome to your MAT 1575 OpenLab site! All course information is posted here. Please take a look around.

OpenLab Homework #1

Your first assignment is to add yourself to our OpenLab course and to submit a post according to the instructions below. Your post is due by 8 am on Monday, February 3. Your post will count toward your participation grade.

  1. Sign up for an OpenLab account using your CityTech email address.
  2. After you’ve logged in, add yourself to our MAT 1575 class.

  1. From the class OpenLab site you can create a new post by clicking the symbol that looks like a + sign inside a circle at the top of the screen.
  2. Title your post “Introducing [your first name] [your last name].” (You may use just initials if you like, as long as there’s enough information for me to locate you on my official roster.)
  3. From the categories on the right-hand side of the screen, make sure to select “Introduce yourself” so that the rest of us can locate your post later.
  4. Tell us anything you’d like us to know about you! Write one paragraph with at least five sentences. Some suggestions are…
    • Your pronouns (examples: she/her/hers or he/him/his or they/them/theirs)
    • Your major
    • How you became interested in your major
    • Which math classes you’ll take after MAT 1575 (if you don’t know, you can check your program requirements in the college catalog here)
    • What you hope to do after you graduate from CityTech; short-term goals, long-term goals, whatever…
    • Other interests/hobbies you have
    • Something you’re good at
    • Something you’re proud of
    • A time when you overcame something difficult
    • Your favorite book
    • Your favorite animal
  5. Read and comment on at least one your classmates’ posts. (Note: the administrator will have to approve your comments, so don’t worry if they don’t appear right away.)
  6. If you have anything private that you’d like to share with me but not with the whole class (for example, if you are to receive a testing accommodation through Student Support Services), please email me directly.

Webwork #1:

Your first Webwork assignment consists of two short sets. Answers are due by Sunday, February 2, 2020 at 11:59pm

  • Review-ChainRule
  • Review-PowerRule
  • Review-ProductRule
  • Review-QuotientRule
  • Antiderivatives

To log into Webwork, follow this link.

  • Your username is your first initial +  your last name. For example, if your name is Barack Obama, your login name is bobama. (If your last name has a space or a hyphen, delete it.) All letters are lower case. Both username and password are case sensitive.
  • Your password is your CUNY EMPLID number.
  • If you can’t log in, let me know after class.

Click on the homework set’s name to view the problems. Click on individual problems and enter your answer. After you have entered an answer, the system will tell you if it is correct. Make sure you have entered all your answers before the deadline. There is nothing else for you to do after that.
