The latest Wolfram Daily Study Group features one of our favorite math instructors, Devendra Kapadia, and focuses on building fundamental concepts in calculus. This is a great opportunity for students to refresh their knowledge or get a head start on the subject. Sign up: https://wolfr.am/od7nlnga
Thank you, Jamie!
I am looking forward to meeting students and learners from all over the world in the study group.
My goal is to provide an easy introduction to AP, high school, or college calculus.
See you all there!

Hello I’m Jonathan
I’m looking to do this to get an idea of how best to help my students.

I am enjoying the conceptual approach to the course. Also, the use of “multiple representations” where the connections between a situation, code, table and graph are made.
Familiarity with the basics of the language can be a tad challenging, however, learning by example is helpful, in addition to introducing options to the examples and to see how things change.
I try to follow with a notebook where I can make annotations and work examples at my own pace. My mother used to say that “Mathematics are learned with a pencil” (not an exact translation, but it gets the message across: practice is important.)
Thank you for the feedback. I am glad that you are enjoying the course, and I agree that practice is important for mastering the subject.
I am having difficulty with an exercise. I do copy/paste to the scratch notebook, and separately to Mathematica and do not see the expected result. Thank you. (apparently I can only add one picture)
Hi Heidi,
I am unable to reproduce the problem. Are you sure you do not have multiple downvalues for f? Try ClearAll@f.
f[x_] := (x^3 - x^2 + 2)/(5 x - 3)
{Limit[f[x], x -> -2], f[-2]}
(* {10/13, 10/13} *)
No luck. I ended up opening a new notebook, setting the default context to Unique, from Evaluation in the Menu Bar. This also allowed me to reset my inputs numeration to 1 and retyped as needed. Is there a way to do that (reset the input numbering) within the same notebook? Thank you!
Hi Heidi,
You can always quit the kernel by evaluating [Quit[]](Quit: Terminate the kernel with optional exit code—Wolfram Documentation).

Hi everyone.
How are you doing the practice exercises? I don’t understand how to use the practice notebook below the videos when I go to the online course. I’m not able to run anything to see the results in there.
Is it possible to receive notebooks of the exercises, similar to how we received copies of the lesson notebooks, so we can work with them in the Mathematica program itself? I just keep struggling going back and forth to try them…
Thanks in advance for your help.
Hi Veronica,
I believe the user has to be signed in into the Cloud for the Scratchbook space to work (?).
I decided to open a second window next to the browser and work the exercises in Mathematica. I need to take my time to type in instead of copy/paste (that did not work for me), it helps me to practice the syntax of the language. I also have a few tabs open at the Documentation Center to look up entries that I do not know about, or not understand, or to alter how graphs render for example.
I am also curious about how others approach the examples and the practice exercises.
I hope this helps. Be well!

FYI, there seems to be an issue with the WSG Calculus week 1 quiz (at least with my copy)…
The wording for question 5 seems to be incorrect (it is the same as for question 6).
Thank you for bringing that to our attention @Dave M ! We will fix this and redeploy the quiz ASAP.
Question 5 should read:
Given that Limit[f[x],x->0,Direction->1] = a and Limit[f[x],x->0,Direction->-1] >> = b, what is the value of Limit[f[x],x->0]?
Properly formatted
Given that
Limit[f[x], x -> 0, Direction -> 1] = a
and
Limit[f[x], x -> 0, Direction -> -1] = b
what is the value of
Limit[f[x], x -> 0]
Where can I get the copy of Quiz 1? I didn’t get it.
I am missing a graph plot in slide 10 of “7DerivativesandRatesofChange.nb”. It is stated: “Plot the function, its derivative and the tangent line”. In my opinion the plot doesn’t show the derivative. I have made the following improvement and would like to get feedback whether it is correct.

Will there be a short overview of the Quiz for Week 1?
Where can I find the link to Quiz 1? Can anyone tell me?
It was sent on the Friday reminder email.
