please solve part b in PYTHON code

3. Given f(x)=2xcos(x) (a) Find the first 8 derivatives of f (NOTE: this can be easily done using list comprehension!). (b) Given a number n that is divisible by 4 , in separate print commands, state the formula for the nth derivative, the (n+1)th derivative, the (n+2)th derivative, and the (n+3)th derivative of f (i.e, f(n)(x),f(n+1)(x),f(n+2)(x), and f(n+3)(x))
