My name is Jyoti Sundaram. I was part of the Calculus Study Group from August 3 to 21 with Devendrá and Cassidy. I was just wondering if you got all three of my quizzes. I just did it today. My email is jyotimeera@icloud.com. When will the certificate come?
POSTED BY: Jyoti Sundaram

Hi @Jyoti Sundaram. Today is the quiz deadline, and we will run our final results report on Monday. Certificates will be sent by Friday, next week. If you don't hear from us by then, please contact wolfram-u@wolfram.com to inquire about the status of your quiz results. Thank you for participating in the calculus study group!

Hello there! Can some one please help me know how would the "Track my Progress" Page appear once you have completed watching the videos and attempted the Quizzes ?

Though I have completed watching about 4 Videos, the Video Progress Bar shows only 2% ( 1 video) completed !!

Thanks.

Hello Lori !

Thanks for your reply. I too had tried the above technique but the system is still not registering it. However, I have reported the issue at wolfram-u@wolfram.com.
POSTED BY: Bijal Amlani

Hi, Bijal!

Frustrating, isn't it?! It is difficult to know if the problem is on our end, or the browser, or WolframU. I always managed to get it going. In fact, I just finished the final yesterday. You'll be successful!

P.S. What time is it where you are, if you don't mind my asking? It's 0430 here.

Quiz 10 from Introduction to Calculus course has been re-deployed. You should be able to access it and take it now. Let us know if you continue to face issues.

In some cases you may have to take the following steps to ensure the latest version is loading in your course:

  • Clear out the browser cache
  • Go to My Files -> Copied Files on your Wolfram Cloud account and delete any copies of Quiz 10
  • Go to My Files -> Trash on your Wolfram Cloud account and delete any copies of Quiz 10
  • Close and reopen browser
POSTED BY: Abrita Chakravarty

@Abrita Chakravarty

Thanks for this update. I completed the Quiz 10 just before, and I want you to do the double check for the following two questions:

The question 2: I think the correct answer is 1.108 (rounded from 1.10763); The question 5: There is a TYPO in the first choice ("A." is inserted).

Please see the attached as well.

Thanks.

Is it possible to get the remaining notebooks and Lessons from the Intro to Calculus course that were not provided during the Study Group. One of the surveys towards the end of the study group sesssions asked if there was interest in obtaining these notebooks.The study group was excellent and I would like to finish the online course. Thanks again for a great Study Group and all of them offered this year!

Hello there! I am trying to catch up on the course. I wasn't able to attend some of the days. I've been watching the recordings on https://www.gotostage.com/channel/daily-study-group but it's missing Days 13 to 15. Will these be uploaded soon for us to catch up before taking the last quiz?

Thanks so much!

Hi Veronica, we will have the recordings available shortly. Meanwhile you can also take a look at the lecture videos in the online course Introduction to Calculus.

POSTED BY: Hee-Young Shin

We are redeploying Quiz 10. It should resolve the issue. I'll post when its ready.

Meanwhile, for those who have not been able to view the updated Quiz 8, one more thing to try: In addition to deleting the copy of 08_quiz.nb from your "Copied Files" directory in your "Cloud Files"/"My Files" directory, please delete any existing copy of the file you may find in "Trash" as well.

Hello,

You are correct. There is an error in the multiple-choice answer to this question (#5 in Quiz 8 (in Introduction to Calculus)). We will have this fixed soon. Thanks.
POSTED BY: Devendra Kapadia

Dear @Devendra and @Abrita,

Here is another call. For some reason, the Quiz 10 (in Introduction to Calculus) does not allow me to click (mark on) the answer among the multiple choice. I suspect that is something to do with 'interactivity' funtionality issue (Not internet connection issue on my part, but something in the program that prevents a user (like me) from choosing a correct answer). Could you please quickly check? (Cf. See also the attached work).

Attachments:
Quiz10.nb
POSTED BY: Hee-Young Shin

Hi Hee-Young, I just tested the quiz. The interactivity seems to be working ok i.e. I am able to select the answers by clicking on the radio-buttons. Note, you may sometimes have to wait a bit to allow the notebook to load completely and become interactive. Initially a non-interactive version of the notebook is displayed.

![notation question][1]

I have encountered an odd square root symbol in the results of a Solve statement as shown in the attached. Can anyone explain this for me?

POSTED BY: Joseph Smith

It stands for the Root symbol. 

Root[f,k]

represents the exact kth root of the polynomial equation f[x]==0.

This was updated in version 12 and more info can be found here http://reference.wolfram.com/language/ref/Root.html

The second root from your solution looks like this in InputForm

Root[-5 - 12 # + #^3& , 1, 0]

You can get the corresponding numeric value with:

Root[-5 - 12*#1 + #1^3 & , 1, 0]//N

Hi Joseph,

They represent the roots of a polynomial. Check the documentation for details. If you are just interested in the numeric values then

sol = Solve[f'[x] == 0, x]
N@sol
(* {{x -> 0.}, {x -> -3.23319}, {x -> -0.422973}, {x -> 3.65617}} *)
POSTED BY: Rohit Namjoshi

In the "Introduction to Calculus" online course, Quiz 7 is the same as Quiz 8. And now, I'm catching up on other posts and see that this issue has been mentioned. Feel free to ignore.

One thing IS certain: one feels much less crazy when the developers have trouble getting code the give the desired results.

Hello Everyone,

The following issues have been resolved for the online course Introduction to Calculus:

  • Quiz 4 Problem 4
  • Quiz 5 Problem 2
  • Quiz 7 Problem 2
  • Quiz 7 Problem 3
  • Quiz 8

In addition, a minor correction has been made to the text of Problem 7 in Quiz 2 released last week for the Calculus Study Group.
POSTED BY: Abrita Chakravarty

Dear @Abrita,

I quickly checked, but for some reason the problem still persists:

  1. Both Quiz 7 and 8 are the same as before, with the answer to the Quiz 8 are wrongly indicated.
  2. The answers to both question #2 and #3 in the Quiz 7 are not accurate.

Best wishes,
POSTED BY: Hee-Young Shin

Hi Hee-Young, Would you try a couple of things and see if it helps?

  • Clear out the browser cache
  • Go to My Files -> Copied Files on your Wolfram Cloud account and delete any copies of Quiz 7 and Quiz 8

Please feel free to let us know if these steps do not help.

Thank you.
POSTED BY: Abrita Chakravarty

It is now working for me, @Abrita. Thank you.

For your reference: It turned out that I needed to close and reopen the browser. Therefore, 1. Clear out the browser cache; 2. Go to Wolfram Cloud -> My Files -> Home -> Copied Files and delete any copies of Quiz 7 and Quiz 8; 3. Close the browser completely and reopen it.
POSTED BY: Hee-Young Shin

Great! Thanks for including the third step of "Closing and re-opening the browser". We'll share it with other users facing similar issues.
POSTED BY: Abrita Chakravarty

Dear Devendra and Jamie,

I have been working on the Introduction to Calculus (https://www.wolfram.com/wolfram-u/introduction-to-calculus/), while taking this daily study group.

I have personally sent to you a number of comments (through the "Feedback" menu) regarding the Wolfram U calculus course including what I think some errors and/or incorrect answers in the Exercises and Quizzes.

For example, most questions in Quiz 8 are repetitions from the previous Quiz (rather than asking to calculate the area or volume of solids), and the question number 2, 3 and 5 do not have an accuract answer.

Could you please quickly check these comments that I sent to you (Please see the attached as well)?

Hi Juergen, The entire course (containing all the lecture videos as well as transcript and full text notebooks) is available online at https://www.wolfram.com/wolfram-u/introduction-to-calculus/what-is-calculus.html. Are you requesting stand-alone notebooks containing the "Full Text" for each lecture?
POSTED BY: Abrita Chakravarty

Hi Abrita,

Yes, please. I would like to have those stand-alone notebooks for units that we do not discuss in the daily study Group. I prefer to add some notes and to extract the online content by copy and paste cost a lot of extra time.
POSTED BY: Jürgen Kanz

We will try to make these available when we send out the updated download link for this week - along with the Q&A and example notebooks.
POSTED BY: Abrita Chakravarty

Hi Jamie,

Is it possible to get also all notebooks of the original online course that we do not discuss in daily study group?
POSTED BY: Jürgen Kanz

Hi,

I have a problem with the result interval of Problem 2, Quiz 5, Online Course. The task is as follows: enter image description here

In my opinion none of the given answers are correct. According to my calculations the result must be c = 1.527525232. Please check.
POSTED BY: Jürgen Kanz

Hello, Juergen!

It's not you. I got a different and the correct answer, also, using Mathematica of course. These WSGs are very popular and since I got a passing score I didn't report it. BUT, QUIZ 8 of the online course just blew up and now only 2 of my answers are correct whereas YESTERDAY I had only missed one: none of the choices on #2 are accepted but one of the IS the correct answer.

How far have you pregressed?
POSTED BY: Lori Johnson

Hi Lori,

Thank you so much for support. I have selected the "correct" answer in the quiz, but I do not believe it is correct.

Reasoning:

  1. Mathematica calculates the "correct" answer according to the quiz.

  2. If you take the "correct" result and you try to draw a parallel line of the secant through the calculated point, it becomes obvious there is a mistake.

  3. I have done the calculation with Maple as well (sorry Wolfram Team).

Here are the results which look correct and logical to me:

Tools >> Tutors >> Calculus >> Single Variable >> Mean Value Theorem Tutor Math App

My worksheet Part 1 Part 1 of my worksheet

My worksheet Part 2 Part 2 of my worksheet
POSTED BY: Jürgen Kanz

I completely agree with your reasoning and conclusion. I tell my students: if you catch my mistakes, it means that you're paying attention! It applies to us, too :D
POSTED BY: Lori Johnson

My calculation with help of the Wolfram Cloud App on my iPad. Same result as Maple solution.

Formula with odd-looking curly bracket

The attached notebook and image shows a Plot statement from the solution to problemset 2 problem 2. Can anyone identify the odd curly bracket just before x^3 and before 13x^2/4?

POSTED BY: Joseph Smith

The curly bracket is a representation of the Piecewise function. This code can also be written as Plot[{Piecewise[{{x^3 + x, x < 2}}], Piecewise[{{(13*x^2)/4 - 3, x >= 2}}]}, {x, 1, 3}]

Thanks to everyone for your attention to Quiz 1 of this Study Group. Each quiz covers topics that were covered the previous week during Study Group. Check your reminder emails for links to the quizzes and other links to Study Group recordings and notebooks. We will not be reviewing the quizzes as a group.

To further clarify, there will be a total of three weekly quizzes. You must pass all three quizzes with a score of 60% or better to earn a certificate of program completion. All scores are recorded, and your best scores will be counted. Quizzes are due by August 28.

Hi I have really enjoyed the course and have been watching it live (with a few sessions I missed and caught up with).

I am a little confused with quiz and the certification process. Do you only need to complete the 3 quizzes (as in email) to gain the certification or do the 3 quizzes AND watch the 50 course videos, complete the 10 quizzes and the final exam as on https://www.wolfram.com/wolfram-u/introduction-to-calculus/track-my-progress.html ? Thank you.
POSTED BY: Chloe Allen

@Chloe Allen, there are three different Wolfram U certifications available related to calculus! 1) To earn a certificate of program completion for the Study Group, you need to have registered for the Study Group, attended the sessions or watched the videos, and pass the three quizzes. 2) To earn a certificate of course completion for Introduction to Calculus, you must watch the course videos and pass the course quizzes. 3) To earn a Level I certificate in calculus, you must complete the interactive course and pass the final exam. The latter two certificates can be monitored using "Track my Progress" from within the course.

Hi @Jamie Peterson , I just saw this reply here, where the expectation was that we attended all the study group sessions or watched the videos in addition to the quizzes. I was not able to attend all the group sessions when they were live, but I was catching up using the GoToStage website. I also passed all three quizzes. Will I still get a certificate in this course? I really appreciated @Devendra Kapadia 's sessions, with the mini polls between lessons. This was why I used GoToStage instead of Calculus 1 page. Will there be a problem?

Thanks again for this course. I'm a PhD student and really needed this review. It's helped me to overcome my fears. :-) Take care.
POSTED BY: Veronica Frans

Hello @Veronica Frans, it is no problem if you did not attend all sessions but watched the videos instead. If you passed the three quizzes, then you will receive a certificate. These should be sent by the end of the week.

Is there a specific due date to this? It just has to be done by tomorrow, right? Will we go over this? We are allowed to retake right? If we retake, is it still that the initial score on the first trial is the one that is recorded? For example, I took it the first time and I got a 70% but I realized my mistakes and selected different answers and earned a 100%. Which score will be recorded in order to be eligible for the course completion?
