Survey on the internet to see is it possible to have a Turing machine that can compute an ODE equation (ordinary differential equation). If yes, use a preferred programing language to code such a machine and include some example results.

Create a formal definition of the language that a Turing machine can understand by writing it out using the set notation.

Design a Turing machine that computes the function for x, a positive integer represented in unary f(x)=(x−2) if  x>2 and f(x)=0  if  x≤2.the image provided is example of similar TM where the function is f(x) = x+1, I'd like the answer and TM to be in similar format as well thank you.
