(c) If $v_s(t) = e^{-2t}$ for $t > 0$ and $v(0) = 1V$, find the value of $v_r(0)$ (i.e., the value of $v_r(t)$ immediately after $t = 0$). P6-2 Find the solution of each of the following differential equations for $t > 0$. (a) $\frac{dy(t)}{dt} + 2y(t) = 3$, $y(0) = 0$ (b) $2\frac{dy(t)}{dt} + y(t) = e^{-t}$, $y(0) = 0$ (c) $\frac{dy(t)}{dt} + \frac{1}{5}y(t) = e^{-t}e^{j t}$, $y(0) = 1$
