Use Matlab to calculate the derivative of the function $()=$ exp$(2)$ at the point $=0.$

Use the diff function, applied to the interval $[0,1],$ with different increments:

$\backslash$Delta $=0\mathrm{.}5,0\mathrm{.}1,0\mathrm{.}05,0\mathrm{.}002,0\mathrm{.}0001$

What is the true derivative? Calculate it by pen and paper!
