Previously in my PhD and now at my job I do a lot of handwriting of mathematics, with accompanying text notes, and I have found mechanical pencils to be the most suitable tool for the job, as they combine the comfort of ergonomically fitting products, low effort for the wrist and repeatedly corre...
@darijgrinberg An attempt in the comments does not count unless somebody edits the attempt into the question body. The editor does not have to be the asker. I have "rescued" several questions by relocating such an attempt into the question body when I felt that the question should be preserved/reopened. I believe that this is the best way. Practice what you preach and all that.
@XanderHenderson It was a valiant effort (in gentle) but it really looks now to be a case of self-sustaining intransigence. Let's leave the room to its fate and actually get some things done here :)
Hi stackexchange community,
My question is regarding Steiner's (incomplete) proof for the Isoperimetric problem
Before I ask, I've done the following:
Read the proof as presented in 'What is Mathematics'
Re-read the proof
Searched the stackexchange for similar questions
Now, my question:

I think that the question is overly chatty. Would anyone object to my editing it down a bit? e.g. the list of things done by the asker seems extraneous.
Thank you, @MartinR. It seems that I upvoted this answer at some point in the past. According to that answer, the question I linked above should be closed on the grounds that it lacks context.

Textbook's Answer
$ \big [e^{\int_{0}^{x} e^{-t^2} dt} \big ]' = \int_{0}^{x} e^{-t^2} dt \cdot e^{-x^2} $
My Answer
$ \big [e^{\int_{0}^{x} e^{-t^2} dt} \big ]' = e^{\int_{0}^{x} e^{-t^2} dt} \cdot e^{-x^2} $
