I just need to know how can Mathematica recognize [itex]e^{-i\theta}[/itex] as the eulers identity. This is, [itex]e^{-i\theta} = cos \theta + sin \theta [/itex].(adsbygoogle = window.adsbygoogle || []).push({});

When i plot a function like [itex]e^{i\theta}[/itex], nothings appear in the graph.

Help is appreciated.
