Is $e^{i\pi}+1=0$ a good motivation for introducing $e$ or $i$? Why (not)?
Most mathematicians would agree that
$$e^{i\pi}+1=0$$
is one of the most impressive formulas.
Imagine your students have just learned about the definition of $e$ or $i$ (just assume it's $e$, norm …

What are easy examples from daily life of constrained optimization?
This example is maybe the most easy, but in my opinion it does not highlight the necessity to use methods of constrained optimization since the constrained equation is explicitly invertible.
