Given that the surface x^8y^7+y^3z^6+z^8x63+6xyz=9 has the equation z=f(x,y) in a neighbourhod of the point (1,1,1) with f(x,y) differentiable, find the derivatives
fx(1,1)=
fy(1,1)=
Attempt: I tried plugging (1,1,1) in fx but it wasnt rigth. We haven't seen this in class and I don't know what to do.
Thanks
