Usually not. The constants $$e$$ and $$\pi$$ have great applications, which should be their motivation.

Maybe in an algebra class that introduces $$i$$, if you're discussing the geometry of the complex plane might, then Euler's formula could be relevant.

Definitely in a differential equations class, where solutions often involve exponentiating complex numbers, Euler's formula is important.
