I'm currently learning complex analysis, and there's something I can't quite get...(adsbygoogle = window.adsbygoogle || []).push({});

Usually:

So why is that:Code (Text):e^2 * e^3 = e^(2+3) = e^5

?Code (Text):e^(i*PI*t) * e^(i*PI) = -e^(i*PI*t)

I was able to get the solution from:

But, what am I missing?Code (Text):e^(i*PI*t) * e^(i*PI) =

= (Cos(PI*t) + iSin(PI*t)) * (Cos(PI) + iSin(PI)) =

= (Cos(PI*t) + iSin(PI*t)) * (-1) =

= -e^(i*PI*t)

Thanks!
