Can anyone explain in simple terms on how they are equal? graphs are welcome.(adsbygoogle = window.adsbygoogle || []).push({});

The thing I don't understand is why exp(jwt) is sinusoidal. Wouldn't exp(jwt) go to infinity when t increases? I don't know how to understand the exp term as sinusoidal? in my mind they simply go to zero or infinity.
