Energy and Power
$ x(t)=x^2\! $
and the limits are from 1 to 3.
Energy calculation
$ E=\int_{1}^{3}\ |x ^2|^2\, dx , \,\! $
$ E=\int_{1}^{3}\ x ^4\, dx , \,\! $ $ E=\frac{1}{5}\! $ *$ ((3^5)\! $ - $ (1^5))\! $ $ E=\frac{1}{5}\! $*$ (243-1)\! $ $ E=48.4\! $
Power calculation
$ P=\frac{1}{(3-2)}\int_{1}^{3}\|x^2|^2\,dx,\,\! $
