Rearranging equation using implicit function thm HELP watch

    • Thread Starter

    Anyone know how to do this?

    Determine whether or not the equation x^2 + y + sin(xy)=0 can be written in the form
    y = f(x) or in the form x = g(y) in some small open disc about the origin for some
    suitable continuously differentiable functions f,g.

    See page 29 here.

    The theorem tells you whether there is a 'solution' y=f(x). It does not help you write such a solution, even if that is possible.

    I think.
Do you agree with the PM's proposal to cut tuition fees for some courses?
