$ x(t)=4\cos(t)+4\jmath\sin(t) $

$ |x(t)|=|4\cos(t)+4\jmath\sin(t)| $

 $ |x(t)|=\sqrt{16\cos^2(t)+16\sin^2(t)} $
 
 $ |x(t)|=4 $

Compute $ E\infty $

 $ E\infty=\int_{-\infty}^\infty |4|^2\,dt=16t|_{-\infty}^\infty $
 $ E\infty=\infty $

Compute $ P\infty $

 $ P\infty=lim_{T \to \infty} \ \frac{1}{(2T)}\int|4|^2dt $
 $ P\infty=lim_{T \to \infty} \ \frac{1}{(2T)}*16|_{-T}^T $
 $ P\infty=lim_{T \to \infty} \ \frac{1}{(2T)}*16(T-(-T)) $
 $ P\infty=lim_{T \to \infty} \ 16 $
 $ P\infty=16 $
