Problem $6(18$ points$)$ Compare the responses of the nonlinear and linearized systems using Matlab function

ODE $23.$ Assume that the system is at the NOP initially. This means plot the responses and compare them.

For part $c,$ let $u\frac{?}{b}=ar(u)+$hat$(u),$ where hat$(u)=-\mathrm{.}06sint.$

Use a time span of $2$ seconds starting at $0.$

You will need to create an $m-$file for the linear system, an $m-$file for the nonlinear system, and a third

$m-$file to call the first two and to create the plot$($s$).$
