okay, so i'm really confused, and i'm not sure where to even start. any direction or advice, would be most appreciated.(adsbygoogle = window.adsbygoogle || []).push({});

for an exercise, we were asked to proove 'euler's formula' (not the polyhedron one)

[tex]e^{-i \phi} = cos \phi + i sin \phi[/tex]

for the 'hint' we were given

[tex]e^x = \sum_{n=0}^\infty \frac{x^n}{n!}[/tex]

so yah, like i said any direction would be most appreciated.
