The current through an inductor of `1H` is given by `i =3t sin t`. Find the voltage across the inductor.

Explanation

To find the voltage across the inductor, we will use the formula for the voltage across an inductor, which is given by:

\[ V_L = L \frac{di}{dt} \]

where:
- \( V_L \) is the voltage across the inductor,
- \( L \) is the inductance (in henries),
- \( \frac{di}{dt} \) is the rate of change of current with respect to time.
