Find the formula for the Laplace transform of the derivative of a function $y$. Use the initial condition $y(0) = y_0$, use $y$ and $y'$ respectively for $y(t)$ and $y'(t)$ and $Y$ for the Laplace transform of $y$. $L\{y'(t)\}(s) = \int_0^\infty e^{-st}y'(t)dt$ $u = e^{-st}$ $dv = y'(t)dt$ $du = -se^{-st}dt$ $v = y(t)$ $= 0 - y(0) + \int_0^\infty sY(s)$ $= sY(s) - y(0)$
