You may want to define a function, to do more complex items. For instance, let us compute the function beta, which will give you the value of beta. To do so$,$ we need the

following code:

def beta$($x$)$:

return x $/299792$

print$($beta$(299792))$

print$($beta$(149896))$

$1\mathrm{.}0$

$0\mathrm{.}5$

Using the function defined above, create a new function computing the Lorentz factor, and plot the Lorentz factor as a function of the speed. You can use as many new entries

as needed; remember to explain what you are doing by adding some markdown entries when relevant.
