Use centered difference approximations to estimate the second derivatives of $y={0\mathrm{.}3}^{**}sin((7\mathrm{.}4+x{)}^2)$ at $x=6\mathrm{.}1$ for $h=0\mathrm{.}03.($argument in radians$)$ Employ $)$ formula for estimating the results. $($Round the final answers to four decimal places.$)$

Attention! sin function in Matlab uses argument in radians
