Determine following signal is periodic if a signal is periodic,specify its fundamental period. In the class I just learn sin,cos signal In H.w. complex exponential signal..... and without fourier transform I need solution Thank you

In the class I just learn sin,cos signal In H.w. complex exponential signal..... and without fourier transform I need solution Thank you $e^{(-1+\jmath)t}=e^{-t}e^{\jmath t}$ $e^{\jmath t}=\cos(t)+\jmath \sin(t)$ That should be all you need to determine if $x(t)$ is periodic or not.
