Formulate Newton’s method for the system
x^3 = y
y^3 = x
Note that this system has three real roots (−1, −1), (0, 0) and
(1, 1). By taking various initial points in the square −2 < x, y
< 2, try to obtain the attraction regions of these three
roots.
P.S. An attraction region of a root is defined as the set of all
initial points which will eventually converge to the root.
