Answer
We can see the table of values below.
Both $L(t)$ and $C(t)$ fluctuate continuously between the values of 3 and 0. It is interesting to note that $E(t)$ stays at a constant value of 3.
Work Step by Step
We can see the table of values below.
$L(t) = 3cos^2(6,000,000~t)$
$C(t) = 3sin^2(6,000,000~t)$
$E(t) = L(t)+C(t)$
Both $L(t)$ and $C(t)$ fluctuate continuously between the values of 3 and 0. It is interesting to note that $E(t)$ stays at a constant value of 3.
