The waveform for the current in the 2 -H inductor shown in Fig. $P 6.36 a$ is given in Fig. $P 6.36 b .$ Determine the following quantities:
(a) the energy stored in the inductor at $t=1.5 \mathrm{ms}$
(b) the energy stored in the inductor at $t=7.5 \mathrm{ms}$
(c) $v_{L}(t)$ at $t=1.5 \mathrm{ms},$ (d) $v_{L}(t)$ at $t=6.25 \mathrm{ms},$ and (e) $v_{L}(t)$
at $t=2.75 \mathrm{ms}$
