Hello, I've been bashing my head against this problem for around 2 hours, looking everywhere to see if I can find a solution in the forums and elsewhere, but I can't.  I'd appreciate it if someone could give me some guidance on how to do the following:

Approximate f(x, y) = (y^2) / (x^3) by a polynomial of degree 6 in x - 1 and y + 1.
