I've had a read through some of the topics about this but I am struggling to understand how to apply it.(adsbygoogle = window.adsbygoogle || []).push({});

(1) Is it possible to apply the inverse function theorem to a function like f(x,y)=-xye(-(x^2+y^2)/2) or f(x,y)=2x^2+y^2-xy-7y

(2) I am confused about how to compute the jacobian matrix when differentating only gives two terms and my matrix needs four?

Any help would be great
