| Oct 15, 2016 at 7:37 | comment | added | Mathieu Baillif | They are first year students in engineering, to be precise, in informatics. In my school the majority has not seen derivatives in their education. But maybe in other countries they would be called something different. | |

| Oct 14, 2016 at 16:24 | comment | added | Mathieu Baillif | Engineers do need derivatives, but I'll introduce them later. Thus I wondered whether I could avoid them for this particular proof. | |
| Oct 14, 2016 at 15:33 | comment | added | Robert Israel | From my experience, engineers are not usually interested in proving things, but they are interested in calculating things. In order to actually find the extrema, they'll want to use derivatives. | |
