Open to Either 🙂

I trust the team will make a good decision.

I expect my students to know them but am not opposed to having it on the reference sheet.

Given the number of formulas students are expected to memorize, I think providing this formula could help them focus more on applying concepts rather than memorizing another formula. With that said, I am open to including it or not including it :)

I believe it was mentioned that these questions had low scores on the final the previous semester and was most likely due to students not memorizing the formulas. If giving them the formulas will increase their chances of answering these questions successfully, I'm all for it.

How do you vote? Just add a comment to the category you are choosing? Like Rennard I expect them to know the distance formula but do not object to providing formulas from 2.4 and 2.5.

I'm ok with either option. The formula for arc length can be extracted from the formula for lateral surface area of revolution

On my first exam, I did not allow students to use formula sheets; I expected them to memorize. Since there will be many formulas to memorize by the end of the semester, I will go along with whatever the team decides.

I am ok with both. I did not give these formulas to my students on my exam1. But the questions regarding the arc length and area of revolution surfaces were to setup the integral.
