Problem $(3)$:

Use MATLAB script file ode $(45$ and $23)$ and MATLAB$/$Simulink to compute and plot the solution of the following first order differential equation then compare the three results by added the solution $(y(t))$ in one graph and the legend for each curve $.$

Note: add the Simulink model in your report.

$3\frac{dy}{dt}-5y=7+3cos(6t),y(0)=4$
