Matlab

 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 x.
Store the final values of f(x) in a column vector named .


WARNING: BE SURE YOUR INITIAL CHOICE OF X_0 DOES NOT RESULT IN A SINGULAR JACOBIAN MATRIX
