Write a script that implements the two-dimensional Newton method for the function f: R^2→ R^2 defined by f(x1+ x2)= (x1^2+ x2^2 -1, cos(πx1)). You may compute the explicit expression of the Jacobian matrix and its inverse to implement it directly. Store your solution in a column vector named . Store the final values of f(x) in a column vector named .
