You try. Use SymPy to put

$2$cos$=3$

in state space form. For consistency, use the same convention we followed before, defining

$=$

and ordering the elements of the nonlinear state as

$[].$

Please also choose your equilibrium point so that

$=0.$

Your result should be two matrices $$

and $$

that are described as NumPy arrays with floating$-$point values.
