Need help programming in MATLAB. Please solve programming in MATLAB.

Using MATLAB, solve the following differential equations numerically. Use an interval of $0,1$ to find your results. You will need to submit the following:

each of the functions used as an input to the ode solver

the commands used to call the ode solver

the commands used to create a plot of your results

a plot of your results showing the numeric solution to the differential equation

Use only one $.$mlx file to complete your work $(5$ points for each problem.$)$

$1$ Solve the equation:

$\frac{dy}{dt}=4-y^2,y(0)=1$

$2$ Solve the equation:

$Dy=y(t)+4\mathrm{.}2sin(y),y(0)=1$

$3$ Solve the equation:

$D^{2}y+4Dy+40y=0,y(0)=1,y^{\text{'}}(0)=4$

$4$ Solve the equation:

$D^{2}y=Dy+y(t)$

$y(0)=1,y^{\text{'}}(0)=1$
