Homework Statement
Show that the equations
xy^2+zu+v^2=3
x^3z+2y-uv=2
xu+yu-xyz=1
can be solved for (x,y,z) as functions of (u,v) near the point (x,y,z,u,v)=(1,1,1,1,1) and find dy/du at (u,v)=(1,1)
Homework Equations
Multivariable calculus differentiation
3. The Attempt at a Solution
I want to know if I'm doing this correctly (I don't think I am). What I did was find the Jacobian and plug the point into that to get a numerical matrix. Then I take determinants of matrices consisting of [x/y/z u v] (or is it [x y z]?) and show that none of them are zero.
Then I find the inverse of [u v] and do [u v]^-1 * [x y z]
I'm not very good at this.
