Q: The Rosenbrock function
f(x,y) = (1 - x)^2 + 100(y - x^2)^2
is a well known test function for optimization methods.
Write a C program which implements 2-D Newton's method to find the minimum of the Rosenbrock function, starting from the point (-2,2). The functions E1(x,y) and E2(x,y) and their x and y partial derivatives should all be coded as functions outside main().
